Constructor Detail

PushBufferStreamAdapter

public PushBufferStreamAdapter(javax.media.protocol.PushSourceStream stream,
                               javax.media.Format format)

Initializes a new PushBufferStreamAdapter instance which reads its data from a specific PushSourceStream with a specific Format

Parameters:

stream - the PushSourceStream the new instance is to read its data from

format - the Format of the specified input stream and of the new instance

Method Detail

read

public void read(javax.media.Buffer buffer)
          throws IOException

Implements PushBufferStream#read(Buffer). Delegates to the wrapped PushSourceStream by allocating a new byte[] buffer of size equal to PushSourceStream#getMinimumTransferSize().

Specified by:

read in interface javax.media.protocol.PushBufferStream

Parameters:

buffer - the Buffer to read

Throws:

IOException - if I/O related errors occurred during read operation

read

protected int read(byte[] buffer,
                   int offset,
                   int length)
            throws IOException

Implements BufferStreamAdapter#read(byte[], int, int). Delegates to the wrapped PushSourceStream.

Specified by:

read in class BufferStreamAdapter<javax.media.protocol.PushSourceStream>

Parameters:

buffer - byte array to read

offset - offset to start reading

length - length to read

Returns:

number of bytes read

Throws:

IOException - if I/O related errors occurred during read operation

setTransferHandler

public void setTransferHandler(javax.media.protocol.BufferTransferHandler transferHandler)

Implements PushBufferStream#setTransferHandler(BufferTransferHandler). Delegates to the wrapped PushSourceStream by translating the specified BufferTransferHandler to a SourceTransferHandler.

Specified by:

setTransferHandler in interface javax.media.protocol.PushBufferStream

Parameters:

transferHandler - a BufferTransferHandler to set
