Class CompositeProcessor

java.lang.Object
  extended by com.tangosol.util.Base
      extended by com.tangosol.util.processor.AbstractProcessor
          extended by com.tangosol.util.processor.CompositeProcessor

All Implemented Interfaces:
ExternalizableLite, PortableObject, InvocableMap.EntryProcessor, java.io.Serializable

public class CompositeProcessor
extends AbstractProcessor
implements ExternalizableLite, PortableObject

The CompositeProcessor represents a collection of entry processors that are invoked sequentially against the same Entry.

Author:
gg/jh 2005.10.31

Field Summary
protected  InvocableMap.EntryProcessor[] m_aProcessor
          The underlying entry processor array.

 

Constructor Summary
CompositeProcessor()
          Default constructor (necessary for the ExternalizableLite interface).
CompositeProcessor(InvocableMap.EntryProcessor[] aProcessor)
          Construct a CompositeProcessor for the specified array of individual entry processors.

 

Method Summary
 boolean equals(java.lang.Object o)
          Compare the ConditionalProcessor with another object to determine equality.
 int hashCode()
          Determine a hash value for the ConditionalProcessor object according to the general Object.hashCode() contract.
 java.lang.Object process(InvocableMap.Entry entry)
          Process a Map.Entry object.
 void readExternal(java.io.DataInput in)
          Restore the contents of this object by loading the object's state from the passed DataInput object.
 void readExternal(PofReader in)
          Restore the contents of a user type instance by reading its state using the specified PofReader object.
 java.lang.String toString()
          Return a human-readable description for this ConditionalProcessor.
 void writeExternal(java.io.DataOutput out)
          Save the contents of this object by storing the object's state into the passed DataOutput object.
 void writeExternal(PofWriter out)
          Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Field Detail

m_aProcessor

protected InvocableMap.EntryProcessor[] m_aProcessor
The underlying entry processor array.

Constructor Detail

CompositeProcessor

public CompositeProcessor()
Default constructor (necessary for the ExternalizableLite interface).

CompositeProcessor

public CompositeProcessor(InvocableMap.EntryProcessor[] 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 java.lang.Object process(InvocableMap.Entry entry)
Process a Map.Entry object.
Specified by:
process in interface InvocableMap.EntryProcessor
Parameters:
entry - the Entry to process
Returns:
the result of the processing, if any

equals

public boolean equals(java.lang.Object o)
Compare the ConditionalProcessor with another object to determine equality.
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.
Returns:
an integer hash value for this ConditionalProcessor object

toString

public java.lang.String toString()
Return a human-readable description for this ConditionalProcessor.
Returns:
a String description of the ConditionalProcessor

readExternal

public void readExternal(java.io.DataInput in)
                  throws java.io.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:
java.io.IOException - if an I/O exception occurs
java.io.NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(java.io.DataOutput out)
                   throws java.io.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:
java.io.IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws java.io.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:
java.io.IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws java.io.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:
java.io.IOException - if an I/O error occurs
