Description

Record of optional conditional restrictions.

TBlobActionConditional is a record of optional conditional restrictions. These restrictions can be used, for example, when copying a blob or when creating a blob snapshot. They provide a way to specify under which conditions the action should happen or not happen.

The fields of the TBlobActionConditional record are listed in the following table:

Field	Meaning
IfSourceModifiedSince	A DateTime value that specifies to copy the blob only if the source blob has been modified since the specified date/time.
IfSourceUnmodifiedSince	A DateTime value that specifies to copy the blob only if the source blob has not been modified since the specified date/time.
IfSourceMatch	Specifies to this conditional header to copy the source blob only if its ETag matches the value specified.
IfSourceNoneMatch	Specifies to this conditional header to copy the blob only if its ETag does not match the value specified.
IfModifiedSince	A DateTime value that specifies to this conditional header to perform one of the following actions: Copying a Blob: only if the destination blob has been modified since the specified date/time. Creating a Snapshot: only if the blob has been modified since the specified date/time.
IfUnmodifiedSince	A DateTime value that specifies to this conditional header to perform the action. Copying a Blob: only if the destination blob has not been modified since the specified date/time. Creating a Snapshot: only if the blob has not been modified since the specified date/time.
IfMatch	Specifies an ETag value to perform the action only if the blob's ETag value matches the value specified. The blob checked is either the destination blob (when copying a blob) or the blob being snapshot (when creating a snapshot).
IfNoneMatch	Specifies an ETag value to perform the action only if the blob's ETag value does not match the value specified. The blob checked is either the destination blob (when copying a blob) or the blob being snapshot (when creating a snapshot).
IfSequenceNumberLessThanOrEqual	Specifies a number that must be greater than or equal to the sequence number. IfSequenceNumberLessThanOrEqual is used in the PutPage action.
IfSequenceNumberLessThan	Specifies a number that must be greater than the sequence number. IfSequenceNumberLessThan is used in the PutPage action.
IfSequenceNumberEquals	Specifies a number that must be equal to the sequence number. IfSequenceNumberEquals is used in the PutPage action.
Create	Creates a new instance of TBlobActionConditional.
PopulateHeaders	Populates the given header list with the key/value pair of any field with an assigned value. Note that the keys used will be the header names, as required by Azure requests. The Headers parameter specifies the headers list to populate.
