Detailed Description

Base class for private data of stream implementations in C++.

Member Function Documentation

check()

DLLLOCAL bool StreamBase::check ( ExceptionSink *  xsink )

inline

Checks that the current thread is the same as when the instance was created or assigned via unassignThread() and reassignThread() and that the stream has not yet been closed.

Parameters

xsink

the exception sink

Returns

true if the checks passed, false if an exception has been raised

Exceptions

STREAM-THREAD-ERROR

if the current thread is not the same as when the instance was created

getName()

virtual DLLLOCAL const char* StreamBase::getName ( )

pure virtual

Returns the name of the class.

Returns

the name of the class

Implemented in PipeOutputStream, InputStreamWrapper, PipeInputStream, OutputStreamWrapper, FileOutputStream, FileInputStream, StringOutputStream, EncodingConversionInputStream, EncodingConversionOutputStream, BinaryOutputStream, BinaryInputStream, StderrOutputStream, StdoutOutputStream, and StringInputStream.

reassignThread()

DLLLOCAL void StreamBase::reassignThread ( ExceptionSink *  xsink )

inline

Reassigns current thread as thread used for stream manipulation, see check()

Parameters

xsink

the exception sink

Exceptions

STREAM-THREAD-ERROR

if the current thread is already assigned to another thread

unassignThread()

DLLLOCAL void StreamBase::unassignThread ( ExceptionSink *  xsink )

inline

Unassigns current thread as thread used for stream manipulation, see check()

Parameters

xsink

the exception sink

Exceptions

STREAM-THREAD-ERROR

if the current thread is not the same as assigned
