TMemoryStream.LoadFromStream procedure
Loads the contents of a stream into memory.
Declaration
procedure LoadFromStream(Stream: TStream)Description
LoadFromStream loads the contents of
Stream into
the memorybuffer of the stream. Any previous contents of the memory
stream are overwritten. Memory is allocated as needed.
The LoadFromStream uses the Size
property of Stream to determine how much memory must be
allocated. Some streams do not allow the stream size to be determined, so
care must be taken when using this method.
This method will work much faster than the use of the CopyFrom method:
Seek(0,soFromBeginning); CopyFrom(Stream,Stream.Size);
because the CopyFrom method copies the contents in blocks, while
LoadFromStream reads the contents of the stream as one big block.
Errors
If an error occurs when reading from the stream, an EStreamError may occur.
