Method Detail

newBufferInput

public static MessageBufferInput newBufferInput(java.io.InputStream in)

reset

public java.io.InputStream reset(java.io.InputStream in)
                          throws java.io.IOException

Reset Stream. This method doesn't close the old resource.

Parameters:

in - new stream

Returns:

the old resource

Throws:

java.io.IOException

next

public MessageBuffer next()
                   throws java.io.IOException

Description copied from interface: MessageBufferInput

Returns a next buffer to read.

This method should return a MessageBuffer instance that has data filled in. When this method is called twice, the previously returned buffer is no longer used. Thus implementation of this method can safely discard it. This is useful when it uses a memory pool.

Specified by:

next in interface MessageBufferInput

Returns:

the next MessageBuffer, or return null if no more buffer is available.

Throws:

java.io.IOException - when IO error occurred when reading the data

close

public void close()
           throws java.io.IOException

Description copied from interface: MessageBufferInput

Closes the input.

When this method is called, the buffer previously returned from MessageBufferInput.next() method is no longer used. Thus implementation of this method can safely discard it.

If the input is already closed then invoking this method has no effect.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface MessageBufferInput

Throws:

java.io.IOException - when IO error occurred when closing the data source
