Project: Stream Extension Classes
Applies to: ~>3.0
This class wraps a stream of type THandleStream or its sub-classes (such as TFileStream) and provides an IStream interface to the stream.
TPJHandleIStreamWrapper descends from, and acts the same as, TPJIStreamWrapper with the exception that the TStatStg structure returned by the Stat method also returns information about file creation, modification and access dates where available.
|Clone||Method of IStream. Creates a new IStream object that accesses the same physical stream. Not supported in this implementation.|
|Commit||Method of IStream. Commits pending changes.|
|CopyTo||Method of IStream. Copies data from the wrapped stream into another stream.|
|Create||Object constructor. Creates a new wrapper object for a given THandleStream instance.|
|LockRegion||Method of IStream. Restricts access to a specified range of bytes in the stream. Not supported in this implementation.|
|Read||Method of IStream. Reads data from the wrapped stream.|
|Revert||Method of IStream. Discards un-committed changes in a transacted stream.|
|Seek||Method of IStream. Changes the seek pointer to a new location.|
|SetSize||Method of IStream. Changes the size of the stream.|
|Stat||Method of IStream. Retrieves the TStatStg structure that provides information about the wrapped stream.|
|UnlockRegion||Method of IStream. Removes access restrictions from a range of bytes in the stream. Not supported in this implementation.|
|Write||Method of IStream. Writes data to the wrapped stream.|
[~>3.0.0] Methods of IStream have protected visibility in TPJHandleIStreamWrapper and cannot be accessed from an object instance referenced by a variable of type TPJHandleIStreamWrapper. The methods can only be accessed via the object’s IStream interface.
[~>3.1] Methods of IStream have public visibility.
TPJHandleIStreamWrapper exposes no properties.
TPJHandleIStreamWrapper exposes no events.
