Field Detail

m_aProcessor

protected InvocableMap.EntryProcessor<K,V,?>[] m_aProcessor

The underlying entry processor array.

Constructor Detail

CompositeProcessor

public CompositeProcessor()

Default constructor (necessary for the ExternalizableLite interface).

CompositeProcessor

public CompositeProcessor(InvocableMap.EntryProcessor<K,V,?>[] aProcessor)

Construct a CompositeProcessor for the specified array of individual entry processors.

The result of the CompositeProcessor execution is an array of results returned by the individual EntryProcessor invocations.

Parameters:

aProcessor - the entry processor array

Method Detail

process

public Object process(InvocableMap.Entry<K,V> entry)

Process a Map.Entry object.

Note: if this method throws an exception, all modifications to the supplied entry or any other entries retrieved via the BackingMapContext.getBackingMapEntry(java.lang.Object) API will be rolled back leaving all underlying values unchanged.

Specified by:

process in interface InvocableMap.EntryProcessor<K,V,Object>

Parameters:

entry - the Entry to process

Returns:

the result of the processing, if any

equals

public boolean equals(Object o)

Compare the ConditionalProcessor with another object to determine equality.

Overrides:

equals in class Object

Returns:

true iff this ConditionalProcessor and the passed object are equivalent ConditionalProcessors

hashCode

public int hashCode()

Determine a hash value for the ConditionalProcessor object according to the general Object.hashCode() contract.

Overrides:

hashCode in class Object

Returns:

an integer hash value for this ConditionalProcessor object

toString

public String toString()

Return a human-readable description for this ConditionalProcessor.

Overrides:

toString in class Object

Returns:

a String description of the ConditionalProcessor

readExternal

public void readExternal(DataInput in)
                  throws IOException

Restore the contents of this object by loading the object's state from the passed DataInput object.

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

IOException - if an I/O exception occurs

NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(DataOutput out)
                   throws IOException

Save the contents of this object by storing the object's state into the passed DataOutput object.

Specified by:

writeExternal in interface ExternalizableLite

Parameters:

out - the DataOutput stream to write the state of this object to

Throws:

IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

in - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

out - the PofWriter to which to write the object's state

Throws:

IOException - if an I/O error occurs
