## com.tangosol.util.processor
Class CompositeProcessor

    java.lang.Object
      com.tangosol.util.Base
          com.tangosol.util.processor.AbstractProcessor
              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
