Type Parameters:

T - the type of the value encoded/decoded or wrapped by this

All Implemented Interfaces:

XdrType

Direct Known Subclasses:

XdrSimple, XdrStructType, XdrUnion

public abstract class AbstractXdrType<T>
extends Object
implements XdrType

Method Detail

encode

public byte[] encode()
              throws IOException

Description copied from interface: XdrType

Encode the type, by recursively.

Specified by:

encode in interface XdrType

Returns:

encoded bytes

Throws:

IOException - e

encode

public void encode(ByteBuffer buffer)
            throws IOException

Description copied from interface: XdrType

Encode the type, by recursively, using the provided buffer.

Specified by:

encode in interface XdrType

Parameters:

buffer - The byte buffer

Throws:

IOException - e

encodeBody

protected abstract void encodeBody(ByteBuffer buffer)
                            throws IOException

Throws:

IOException

decode

public void decode(byte[] content)
            throws IOException

Description copied from interface: XdrType

Decode the content bytes into this type.

Specified by:

decode in interface XdrType

Parameters:

content - The content bytes

Throws:

IOException - e

encodingLength

public int encodingLength()
                   throws IOException

Description copied from interface: XdrType

            throws IOException

Description copied from interface: XdrType

Decode the content bytes into this type.

Specified by:

decode in interface XdrType

Parameters:

content - The content bytes

Throws:

IOException - e

getValue

public T getValue()

setValue

public void setValue(T value)

getDataType

public XdrDataType getDataType()
