Method Summary | |
---|---|
java.nio.channels.ReadableByteChannel |
getChannel()
Returns a channel with the representation's content. If it is supported by a file, a read-only instance of FileChannel is returned. This method is ensured to return a fresh channel for each invocation unless it is a transient representation, in which case null is returned. |
void |
release()
Closes and releases the readable channel. |
void |
setChannel(java.nio.channels.ReadableByteChannel channel)
Sets the readable channel. |
void |
write(java.nio.channels.WritableByteChannel writableChannel)
Writes the representation to a byte channel. |
