Member Function Documentation

void org.ccnx.ccn.protocol.WirePacket.decode ( XMLDecoder  decoder  )  throws ContentDecodingException [virtual]

Decode this object as the top-level item in a new XML document, reading it from a network buffer.

Reads document start and end. Assumes default encoding.

Parameters:
buf input stream to read from
Exceptions:
ContentDecodingException if there is an error decoding the content Decode this object as the top-level item in a new XML document, reading it from a network buffer. Reads document start and end.
Parameters:
buf input stream to read from
codec the codec to use; must be recognized by XMLCodecFactory
Exceptions:
ContentDecodingException if there is an error decoding the content
See also:
XMLCodecFactory Decode this object during an ongoing decoding pass; this is what subclasses generally need to know how to implement. Reads just the object itself, higher-level processes have handled start and end document if need be. Allows object to be read using the same code whether it is a top-level element written alone, or nested inside another element.
Parameters:
decoder the decoder being used; encapsulates state including the codec being used as well as the input source and current offset

Implements org.ccnx.ccn.impl.encoding.GenericXMLEncodable.

void org.ccnx.ccn.protocol.WirePacket.encode ( XMLEncoder  encoder  )  throws ContentEncodingException [virtual]

Encode this object during an ongoing encoding pass; this is what subclasses generally need to know how to implement.

Writes just the object itself, higher-level processes have handled start and end document if need be. Allows object to be written using the same code whether it is a top-level element written alone, or nested inside another element.

Parameters:
encoder the encoder being used; encapsulates state including the codec being used as well as the output destination and current offset

Implements org.ccnx.ccn.impl.encoding.GenericXMLEncodable.

boolean org.ccnx.ccn.protocol.WirePacket.validate (  )  [virtual]

Make sure all of the necessary fields are filled in prior to attempting to encode.

All implementations of encode(XMLEncoder) should call this for their classes prior to encoding.

Returns:
true if object is valid and can be encoded, false if there is a problem; for example mandatory fields are uninitialized

Implements org.ccnx.ccn.impl.encoding.GenericXMLEncodable.

long org.ccnx.ccn.protocol.WirePacket.getElementLabel (  )  [virtual]

Allow the encoder/decoder to retrieve the top-level element name programmatically.

This allows subclasses to rename elements without changing their encoder/decoders.

Returns:
the element label to use, as a key in a loaded encoding dictionary

Implements org.ccnx.ccn.impl.encoding.GenericXMLEncodable.
