Constructor Detail

PullBufferStreamAdapter

public PullBufferStreamAdapter(javax.media.protocol.PullSourceStream stream,
                               javax.media.Format format)

Initializes a new PullBufferStreamAdapter instance which reads its data from a specific PullSourceStream with a specific Format

Parameters:

stream - the PullSourceStream 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 PullBufferStream#read(Buffer). Delegates to the wrapped PullSourceStream by either allocating a new byte[] buffer or using the existing one in the specified Buffer.

Specified by:

read in interface javax.media.protocol.PullBufferStream

Parameters:

buffer - Buffer to read

Throws:

IOException - if I/O 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 PullSourceStream.

Specified by:

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

Parameters:

buffer - byte array to read

offset - to start reading

length - length to read

Returns:

number of bytes read

Throws:

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

willReadBlock

public boolean willReadBlock()

Implements PullBufferStream#willReadBlock(). Delegates to the wrapped PullSourceStream.

Specified by:

willReadBlock in interface javax.media.protocol.PullBufferStream

Returns:

true if this stream will block on read operation, false otherwise
