hasDelta

public boolean hasDelta()

Description copied from interface: Delta

Returns true if this object has pending changes it can write out.

Specified by:

hasDelta in interface Delta

toDelta

public void toDelta(java.io.DataOutput out)
             throws java.io.IOException

Description copied from interface: Delta

This method is invoked on an application object at the delta sender, if GemFire determines the presence of a delta by calling Delta.hasDelta() on the object. The delta is written to the DataOutput object provided by GemFire. Any delta state should be reset in this method.

Specified by:

toDelta in interface Delta

Throws:

java.io.IOException

fromDelta

public void fromDelta(java.io.DataInput in)
               throws java.io.IOException,

Description copied from interface: Delta

This method is invoked on an existing application object when an update is received as a delta. This method throws an InvalidDeltaException when the delta in the DataInput cannot be applied to the object. GemFire automatically handles an InvalidDeltaException by reattempting the update by sending the full application object.

Specified by:

fromDelta in interface Delta

Throws:

java.io.IOException

InvalidDeltaException

Since 5.7 it is possible for any method call to the specified DataOutput to throw GemFireRethrowable. It should not be caught by user code. If it is it must be rethrown.

Specified by:

toData in interface DataSerializable

Specified by:

toData in interface DeltaSessionInterface

Throws:

java.io.IOException - A problem occurs while writing to out

fromData
