Field Detail

m_aExtractor

protected ValueExtractor[] m_aExtractor
The ValueExtractor array.

Constructor Detail

AbstractCompositeExtractor

public AbstractCompositeExtractor()
Default constructor

AbstractCompositeExtractor

public AbstractCompositeExtractor(ValueExtractor[] aExtractor)
Construct a AbstractCompositeExtractor based on the specified ValueExtractor array.
Parameters:
aExtractor - the ValueExtractor array

Method Detail

getExtractors

public ValueExtractor[] getExtractors()
Obtain the ValueExtractor array.
Returns:
the ValueExtractor array

equals

public boolean equals(java.lang.Object o)
Compare the AbstractCompositeExtractor with another object to determine equality. Two AbstractCompositeExtractor objects are considered equal iff they belong to the same class and their underlying ValueExtractor arrays are deep-equal.
Specified by:
equals in interface ValueExtractor
Specified by:
equals in interface java.util.Comparator
Parameters:
o - the reference object with which to compare
Returns:
true iff this AbstractCompositeExtractor and the passed object are equivalent
See Also:
Object.equals(java.lang.Object), Object.hashCode()

hashCode

public int hashCode()
Determine a hash value for the MultiExtractor object according to the general Object.hashCode() contract.
Specified by:
hashCode in interface ValueExtractor
Returns:
an integer hash value for this ValueExtractor object

toString

public java.lang.String toString()
Return a human-readable description for this ValueExtractor.
Specified by:
toString in interface ValueExtractor
Returns:
a String description of the ValueExtractor

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
