public void fromDelta(java.io.DataInput in)

```
    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
  - hasDelta
```
public boolean hasDelta()
```
    Description copied from interface: Delta
    
    Returns true if this object has pending changes it can write out.

    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
  - fromData
```
public void fromData(java.io.DataInput in)
              throws java.io.IOException,
                     java.lang.ClassNotFoundException
```
    Description copied from interface: DataSerializable
    
    Reads the state of this object as primitive data from the given DataInput.
    
    Specified by:
    
    fromData in interface DataSerializable
    
    Throws:
    
    java.io.IOException - A problem occurs while reading from in
    
    java.lang.ClassNotFoundException - A class could not be loaded while reading from in
  - toData
```
public void toData(java.io.DataOutput out)
            throws java.io.IOException
```
    Description copied from interface: DataSerializable
    
    Writes the state of this object as primitive data to the given DataOutput.
    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
    
    Throws:
    
    java.io.IOException - A problem occurs while writing to out
