All Implemented Interfaces:

PofValue

Enclosing class:

PofSparseArray

protected static class PofSparseArray.NilPofValue

extends SimplePofValue

NilPofValue represents a value that does not exist in the original POF stream.

Constructor Summary

PofSparseArray.NilPofValue(PofValue valueParent, PofContext ctx, int of, int nType, int nIndex)
Construct a NilPofValue instance.

Method Summary

ReadBuffer	getSerializedValue() Return this value's serialized form.
Object	getValue(int nType) Return the deserialized value which this PofValue represents.
void	setValue(Object oValue) Update this PofValue. <p/> The changes made using this method will be immediately reflected in the result of PofValue.getValue() method, but will not be applied to the underlying POF stream until the PofValue.applyChanges() method is invoked on the root PofValue.

Constructor Detail

PofSparseArray.NilPofValue

public PofSparseArray.NilPofValue(PofValue valueParent,
                                  PofContext ctx,
                                  int of,

                                  int nIndex)

Construct a NilPofValue instance.

Parameters:

valueParent - parent value within the POF stream

ctx - POF context to use when reading or writing properties

of - offset of this value from the beginning of POF stream

nType - POF type identifier for this value

nIndex - index of this value within the parent sparse array

Method Detail

getValue

public Object getValue(int nType)

Return the deserialized value which this PofValue represents.

Specified by:

getValue in interface PofValue

Overrides:

getValue in class AbstractPofValue

Parameters:

nType - the required Pof type of the returned value or PofConstants.T_UNKNOWN if the type is to be inferred from the serialized state

Returns:

the deserialized value

setValue

public void setValue(Object oValue)

Update this PofValue. <p/> The changes made using this method will be immediately reflected in the result of PofValue.getValue() method, but will not be applied to the underlying POF stream until the PofValue.applyChanges() method is invoked on the root PofValue.

Specified by:

setValue in interface PofValue

Overrides:

setValue in class AbstractPofValue

Parameters:

oValue - new deserialized value for this PofValue

getSerializedValue

public ReadBuffer getSerializedValue()

Return this value's serialized form.

Overrides:

getSerializedValue in class AbstractPofValue

Returns:

this value's serialized form
