All Implemented Interfaces:

Marshaller

public class ApacheAvroMarshaller
extends AbstractMarshaller

This is a portable serialization marshaller based on Apache Avro. It supports basic type and collection marshalling. Basic types include UTF-8 String, int long, float, double, boolean and null, and the collections supported include arrays, list, map and set composed of basic types. Primitive types short and byte are not supported per se. Instead, pass integers which will be encoded efficiently using variable-length (http://lucene.apache.org/java/2_4_0/fileformats.html#VInt) zig zag (http://code.google.com/apis/protocolbuffers/docs/encoding.html#types) coding. Primitive arrays not supported except byte arrays. Instead, use their object counter partners, i.e. Integer...etc. For more detailed information, go to: http://community.jboss.org/docs/DOC-15774

Method Detail

objectToBuffer

protected ByteBuffer objectToBuffer(Object o,
                                    int estimatedSize)
                             throws IOException

Description copied from class: AbstractMarshaller

This is a convenience method for converting an object into a ByteBuffer which takes an estimated size as parameter. A ByteBuffer allows direct access to the byte array with minimal array copying

Specified by:

objectToBuffer in class AbstractMarshaller

Parameters:

o - object to marshall

estimatedSize - an estimate of how large the resulting byte array may be

Returns:

a ByteBuffer

Throws:

IOException

objectFromByteBuffer

public Object objectFromByteBuffer(byte[] buf,
                                   int offset,
                                   int length)
                            throws IOException

Description copied from interface: Marshaller

Unmarshalls an object from a specific portion of a byte array.

Parameters:

buf - byte array containing the binary representation of an object. Must not be null.

offset - point in buffer to start reading

length - number of bytes to consider

Returns:

an object

Throws:

IOException - if unmarshalling cannot complete due to some I/O error

isMarshallable

public boolean isMarshallable(Object o)

Description copied from interface: Marshaller

A method that checks whether the given object is marshallable as per the rules of this marshaller.

Parameters:

o - object to verify whether it's marshallable or not

Returns:

true if the object is marshallable, otherwise false
