Values

[.NET] [C++]	[Pascal]	Description
msoaNone = 0	msoaNone	Object will always be accessed
msoaIfModifiedSince = 1	msoaIfModifiedSince	Object will be accessed only if it has been modified since modification time passed to the Read function
msoaIfUnmodifiedSince = 2	msoaIfUnmodifiedSince	Object will be accessed only if it has not been modified since modification time passed to the Read function
msoaIfMatch = 3	msoaIfMatch	Object will be accessed only if its ETag matches the value passed to the Read function
msoaIfNoneMatch = 4	msoaIfNoneMatch	Object will be accessed only if its ETag does not match the value passed to the Read function
msoaIfSequenceNumberIsLessThanOrEqual = 5	msoaIfSequenceNumberIsLessThanOrEqual	Object will be accessed only if its sequence number is less than or equal to the value passed to the Read function
msoaIfSequenceNumberIsLess = 6	msoaIfSequenceNumberIsLess	Object will be accessed only if its sequence number is less than the value passed to the Read function
msoaIfSequenceNumberIsEqual = 7	msoaIfSequenceNumberIsEqual	Object will be accessed only if its sequence number is equal to the value passed to the Read function
