Remarks

When this method is called, the class will close the current archive and release all resources.

Config Method (Officedoc Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

ExtractPart Method (Officedoc Class)

Reads the contents of the currently selected part.

Syntax

public void extractPart();

Remarks

If the part specified by the PartName property exists, the corresponding physical file will be extracted from the archive and will be available through the PartData property.

If the part doesn't exists, or it's stored in interleaved format, an error will be raised.

FindPartByType Method (Officedoc Class)

Looks up a part in the current relationships file by it's type namespace URI.

Syntax

public String findPartByType(String typeURI);

Remarks

If a matching part can be found, it's part name is returned. Otherwise, an empty string is returned.

GetPropertyValue Method (Officedoc Class)

Returns the value of the specified package property.

Syntax

public String getPropertyValue(String propName, String propNamespace);

Remarks

Looks up a package property named PropName in namespace PropNamespace in the core and app properties tables and returns it's value, if found.

If the property doesn't exists, an empty string is returned.

For custom properties. use an empty string ("") as the value of the PropNamespace parameter.

ListParts Method (Officedoc Class)

List all the parts contained in the document and their relationships.

Syntax

public void listParts();

Remarks

When this method is called, the class will read all the relationships in the document, recursively, and populate the Relationships collection.

Open Method (Officedoc Class)

Opens the Open XML package archive.

Syntax

public void open();

Remarks

When this method is called, the class will attempt to open the archive specified in PackagePath and extract package properties, content types and parse the master relationships file in the archive.

ParsePart Method (Officedoc Class)

Parses the specified part as XML.

Syntax

public void parsePart();

Remarks

If the part specified by PartName exists, the corresponding physical file will be extracted from the archive and parsed as XML. If BuildDOM is enabled, the DOM will be built internally and you can use XPath to query the resulting document, using the XPath property. If BuildDOM is disabled, only the XML parser-related events will be fired.

ReadRelationships Method (Officedoc Class)

Reads the relationships file in the archive associated with the specified part.

Syntax

public void readRelationships();

Remarks

When this method is called, the class will look for a .rels file associated with the part specified by the PartName property. If found, the Relationships collection will now expose the contents of the relationships for that part.

ReplacePart Method (Officedoc Class)

Replaces the contents of the specified part in the package.

Syntax

public void replacePart();

Remarks

If the part specified by the PartName property exists, the corresponding physical file will be replaced with the contents of the PartData property. The package file will be modified in place right away.

If the part doesn't exists, it's stored in interleaved format, or PartData is null or empty, an error will be raised.

Reset Method (Officedoc Class)

Resets the class.

Syntax

public void reset();

Remarks

Reset resets the state of the class. All properties will be set to their default values, and any files open will be closed.

ResolveContentType Method (Officedoc Class)

Returns the content type of the specified part.

Syntax

public String resolveContentType();

Remarks

Applies the content type resolution rules specified in the Open XML packaging specification and returns the content type associated with PartName in the archive.

If there's no content type mapped for the part or for the extension, an empty string is returned.

BeginFile Event (Officedoc Class)

Fired before each file is processed.

Syntax

public class DefaultOfficedocEventListener implements OfficedocEventListener {
  ...
  public void beginFile(OfficedocBeginFileEvent e) {}
  ...
}

public class OfficedocBeginFileEvent {
  public int index;
  public boolean skip;
}

Remarks

BeginFile is fired before each file is processed by the compressor or decompressor, as appropriate. Index contains the array index of the file about to be processed, and the CompressedName, DecompressedName, CompressedSize (decompression only), and DecompressedSize fields of the Files collection for this index contain more detailed information about the file about to be processed.

When extracting, an alternate location may be specified by trapping the event, and modifying DecompressedName and/or ExtractToPath. If the appropriate value of DecompressedName is set to an empty string, the file will not be written to disk. If WriteToProgressEvent is true, the file will still be decompressed, and the data may be extracted through the Progress event.

This event may also be trapped while compressing. CompressedName and DecompressedName may be changed.

You may set the Skip parameter to true in order to skip the file completely while compressing or extracting.

}

public class OfficedocOverwriteEvent {
  public String filename;
  public boolean overwrite;
}

Remarks

Overwrite is fired when a file is about to be overwritten, and would overwrite an existing file. The event is fired during decompression.

Filename contains the full name of the file, specified with its pathname.

Overwrite specifies whether or not the file will be overwritten. For Zip, Jar, and Tar, this is equal by default to the value of the OverwriteFiles property. For Gzip, this value defaults to true.

Either of the parameters may be changed when the event is fired. Changing the value of Overwrite will override the default behavior of the class, and cause the file to be overwritten or not overwritten, depending on the value set. If Filename is changed, the value of Overwrite will be ignored, and the file will be written with the specified name. If a file of the new name also exists this file will be silently overwritten.

PI Event (Officedoc Class)

Fired when a processing instruction section is encountered.

Syntax

public class DefaultOfficedocEventListener implements OfficedocEventListener {

}

public class OfficedocProgressEvent {
  public byte[] data;
  public String filename;
  public long bytesProcessed;
  public int percentProcessed;
}

Remarks

The Progress event is automatically fired as compression or decompression is performed. When WriteToProgressEvent is true, the output data is provided through the Data parameter, allowing for it to be streamed out.

Filename contains the name of the file being written. If no file is being written, Filename will contain an empty string, and the output data will be provided exclusively through this event.

BytesProcessed contains the total number of uncompressed bytes processed. PercentProcessed contains the percent of uncompressed bytes processed, corresponding roughly to the running time of the operation.

For Gzip extraction only, BytesProcessed and PercentProcessed will reflect the number of compressed bytes extracted, as it is generally impossible to predetermine the total uncompressed size.

If WriteToProgressEvent is false, Data will contain null.

SpecialSection Event (Officedoc Class)

Fired when a special section is encountered.

Syntax

public class DefaultOfficedocEventListener implements OfficedocEventListener {
  ...
  public void specialSection(OfficedocSpecialSectionEvent e) {}
  ...
}

public class OfficedocSpecialSectionEvent {

Configuration Settings (Officedoc Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

OfficeDoc Configuration Settings

NormalizePartName:   Whether to normalize Part Names.

Sometimes the Part Names retrieved from a document will be of a format that is not directly usable in the PartName property when retrieving the part. For example: /ppt/slides/../media/image1.jpeg

When this option is set to True the component will automatically normalize these Part Names so that they can be directly used in the PartName property for retrieving the part. For example, the above would become: /ppt/media/image1.jpeg

The default is True.

RelationshipIsExternal[x]:   Whether the relationship part is internal or external.

Some relationships in an Office document may be external items, such as URLs and files on disk. These relationships are not directly accessible via ExtractPart. This configuration option will return "True" if the relationship at index "x" of Relationships is an external part. Otherwise it will return "False"

Base Configuration Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Tells the class whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
UseDaemonThreads:   Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions where applicable. Setting this to true tells the class to use the internal implementation instead of using the system's security API.

Trappable Errors (Officedoc Class)

Errors

The following errors may be generated by the class. Note that frequently the error message will contain more specific information than what is listed here.

Note that some non-fatal errors may be trapped and explicitly ignored in the Error event. This will allow the class to continue operation even in case of error.

OfficeDoc Errors

268   The specified part name could not be found on the package, or the part is stored in interleaved format.
