Detailed Description

Stream writer classes provide a specialized write-interface for a stream. This is the abstract base class for all stream writers. It is possible to attach any number of readers and writers to the same stream.

void IO::StreamWriter::SetStream ( const Ptr< Stream > &  s  ) 

set stream to write to

Attaches the writer to a stream. This will imcrement the refcount of the stream.

Reimplemented in Messaging::MessageWriter.

const Ptr< Stream > & IO::StreamWriter::GetStream (  )  const

get currently set stream

Get pointer to the attached stream. If there is no stream attached, an assertion will be thrown. Use HasStream() to determine if a stream is attached.

bool IO::StreamWriter::HasStream (  )  const

return true if a stream is set

Returns true if a stream is attached to the writer.

int Core::RefCounted::GetRefCount (  )  const [inline, inherited]

get the current refcount

Return the current refcount of the object.

void Core::RefCounted::AddRef (  )  [inline, inherited]

increment refcount by one

Increment the refcount of the object.

void Core::RefCounted::Release (  )  [inline, inherited]

decrement refcount and destroy object if refcount is zero

Decrement the refcount and destroy object if refcount is zero.

const Util::String & Core::RefCounted::GetClassName (  )  const [inline, inherited]

get the class name

Get the class name of the object.

Util::FourCC Core::RefCounted::GetClassFourCC (  )  const [inline, inherited]

get the class FourCC code

Get the class FourCC of the object.

void Core::RefCounted::DumpRefCountingLeaks (  )  [static, inherited]

dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)

This method should be called as the very last before an application exits.
