Constructor & Destructor Documentation

AbstractBufferInput ( AbstractReadBuffer::View  vBuf  )  [protected]

Create a new AbstractBufferInput instance that delegates to the given AbstractReadBuffer.

Parameters:
vBuf  the delegate AbstractReadBuffer

Member Function Documentation

virtual void setOffsetInternal ( size32_t  of  )  [protected, virtual]

Update the internal stream offset.

Parameters:
of  the new offset

virtual String::View readUTF ( size32_t  cb  )  [protected, virtual]

Reads the specified-length UTF-8 data and converts it to a String value.

Parameters:
cb  the number of bytes that the UTF data takes up in the stream
Returns:
a String value
Exceptions:
UTFDataFormatException  if the bytes that were read were not a valid UTF-8 encoded string
EOFException  if the value could not be read because no more data remains to be read
IOException  if an I/O error occurs

virtual String::View convertUTF ( size32_t  of,
size32_t  cb  
) const [protected, virtual]

Convert a UTF-8 encoded section of the binary stream into a String.

Parameters:
of  the offset within the stream
cb  the length in bytes within the stream
Returns:
the String value
Exceptions:
IOException  on convertion error
