Detailed Description

BlockRef attribute. Identifies the type of encryption, if the WHIP data is encrypted.

Deprecated:
This class is only used in the context of a WT_BlockRef object, which has been deprecated. Further, this opcode was primarily intended for future data encryption support that was never realized. This remains in the toolkit only for backward compatability with DWF version 00.55.
Examples:

WhipExamples/WriteRedline.cpp.

Member Function Documentation

WT_Result WT_Encryption::materialize WT_Opcode const &  opcode,
WT_File file
[virtual]
 

Materializes the contents of the object from the file and the given opcode.

Reads in the object data and causes the file reading to proceed to the end of this object.

Warning:
This is used by the framework and should not be called by client code.
Return values:
WT_Result::Success The operation was successful.
WT_Result::Opcode_Not_Valid_For_This_Object The object does not support the opcode type.
WT_Result::Internal_Error Something went very wrong.

Implements WT_Object.

WT_Result WT_Encryption::process WT_File file  )  [virtual]
 

Calls the configured action handler for this object (passes in the file reference.).

Warning:
This is used by the framework and should not be called by client code.

Implements WT_Object.

WT_Result WT_Encryption::serialize WT_File file  )  const [virtual]
 

Causes the serialization of the object to the file.

If this is a WT_Drawable derived object, this method may cause the object to be delayed (in case a coincident like-object follows) and/or merged (in case a coincident like-object preceeded) so as to optimize the output.

Return values:
WT_Result::Success The operation was successful.

Implements WT_Object.

WT_Result WT_Encryption::skip_operand WT_Opcode const &  opcode,
WT_File file
[virtual]
 

Causes the file reading to proceed to the end of this object.

Warning:
This is used by the framework and should not be called by client code.
Bug:
Not all objects perform skip_operand() correctly; this is a known problem. For best results, if client code must use WT_File::get_next_object_shell() manually, it should also call the corresponding WT_Object::materialize() method to avoid this problem.
See also:
WT_File::get_next_object_shell(), WT_File_Heuristics::set_deferred_delete().

Reimplemented from WT_Object.
