Detailed Description

Input stream based on AByteBuffer with memory control, clears byte buffer on destruction.

Member Function Documentation

isEof()

bool AStrongByteBufferInputStream::isEof ( )

overridevirtual

returns true if end of stream has been reached

Returns

true if end of stream has been reached

Implements ISeekableInputStream.

read()

size_t AStrongByteBufferInputStream::read ( char * dst, size_t size )

overridevirtual

Reads up to size bytes from stream. Blocking (waiting for new data) is allowed.

Sneaky exceptions

An implementation can throw any exception that subclasses AIOException.

Parameters

dst	destination buffer
size	destination buffer's size. > 0

Returns

number of read bytes (including 0)

Implements IInputStream.

seek()

void AStrongByteBufferInputStream::seek ( std::streamoff offset, std::ios::seekdir seekDir )

overridevirtual

change reading position, a way of changing depends on seekDir parameter

Implements ISeekableInputStream.

tell()

size_t AStrongByteBufferInputStream::tell ( )

overridevirtual

return current reading position

Returns

current reading pos

Implements ISeekableInputStream.
