Constructor Detail

AbstractPullBufferStream

protected AbstractPullBufferStream(javax.media.protocol.PullBufferDataSource dataSource,
                                   javax.media.control.FormatControl formatControl)

Initializes a new AbstractPullBufferStream instance which is to have its Format-related information abstracted by a specific FormatControl.

Parameters:

dataSource - the PullBufferDataSource which is creating the new instance so that it becomes one of its streams

formatControl - the FormatControl which is to abstract the Format-related information of the new instance

Method Detail

willReadBlock

public boolean willReadBlock()

Determines if PullBufferStream.read(Buffer) will block.

Specified by:

willReadBlock in interface javax.media.protocol.PullBufferStream

Returns:

true if read block, false otherwise
