Method Detail

hasDelta

public boolean hasDelta()

Specified by:

hasDelta in interface com.gemstone.gemfire.Delta

toDelta

public void toDelta(DataOutput out)
             throws IOException

Specified by:

toDelta in interface com.gemstone.gemfire.Delta

Throws:

IOException

fromDelta

public void fromDelta(DataInput in)
               throws IOException

Specified by:

fromDelta in interface com.gemstone.gemfire.Delta

Throws:

IOException

equals

public boolean equals(Object o)

Two DeltaPSTObjects are considered to be equal if they have the same values for field1, field2 and timestamp. This provides stronger validation than the PSTObject.validate(int) method that only considers the index.

Overrides:

equals in class PSTObject

clone

public Object clone()
             throws CloneNotSupportedException

Makes a deep copy of this object.

Overrides:

clone in class Object

Throws:

CloneNotSupportedException
