Inheritance diagram for IO::BinaryReader:

IO::StreamReader Core::RefCounted


Detailed Description

A friendly interface to read binary data from a stream. Optionally the reader can use memory mapping for optimal read performance. Performs automatic byte order conversion if necessary.

Todo:
convert endianess!

Member Function Documentation

void IO::StreamReader::SetStream ( const Ptr< Stream > &  s  )  [inherited]

set stream to read from

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

Reimplemented in Messaging::MessageReader.

const Ptr< Stream > & IO::StreamReader::GetStream (  )  const [inherited]

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::StreamReader::HasStream (  )  const [inherited]

return true if a stream is set

Returns true if a stream is attached to the reader.

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.
