public ObjectSerializationDecoder()

Creates a new instance with the ClassLoader of the current thread.

ObjectSerializationDecoder

public ObjectSerializationDecoder(java.lang.ClassLoader classLoader)

Creates a new instance with the specified ClassLoader.

Method Detail

getMaxObjectSize

public int getMaxObjectSize()

Returns the allowed maximum size of the object to be decoded. If the size of the object to be decoded exceeds this value, this decoder will throw a BufferDataException. The default value is 1048576 (1MB).

setMaxObjectSize

public void setMaxObjectSize(int maxObjectSize)

Sets the allowed maximum size of the object to be decoded. If the size of the object to be decoded exceeds this value, this decoder will throw a BufferDataException. The default value is 1048576 (1MB).

doDecode

protected boolean doDecode(IoSession session,
               ByteBuffer in,
               ProtocolDecoderOutput out)
                    throws java.lang.Exception

Description copied from class: CumulativeProtocolDecoder

Implement this method to consume the specified cumulative buffer and decode its content into message(s).

Specified by:

doDecode in class CumulativeProtocolDecoder

in - the cumulative buffer

Returns:

true if and only if there's more to decode in the buffer and you want to have doDecode method invoked again. Return false if remaining data is not enough to decode, then this method will be invoked again when more data is cumulated.

Throws:

java.lang.Exception - if cannot decode in.
