Field Detail

m_predicate

protected Predicate<? super E> m_predicate

The Predicate for filtering extracted values.

Constructor Detail

PredicateFilter

public PredicateFilter()

Deserialization constructor.

PredicateFilter

public PredicateFilter(Predicate<? super E> predicate)

Constructs a PredicateFilter.

Parameters:

predicate - predicate for testing the value

PredicateFilter

public PredicateFilter(ValueExtractor<? super T,? extends E> extractor,
                       Predicate<? super E> predicate)

Constructs a PredicateFilter.

Parameters:

extractor - the ValueExtractor for extracting a value

predicate - predicate for testing the extracted value

PredicateFilter

public PredicateFilter(String sMethodName,
                       Predicate<? super E> predicate)

Constructs a PredicateFilter.

Parameters:

sMethodName - the method to extract a value for testing

predicate - predicate for testing the extracted value

Method Detail

evaluateExtracted

protected boolean evaluateExtracted(E extracted)

Description copied from class: ExtractorFilter

Evaluate the specified extracted value.

Specified by:

evaluateExtracted in class ExtractorFilter<T,E>

Parameters:

extracted - an extracted value to evaluate

Returns:

true iff the test passes

readExternal

public void readExternal(DataInput in)
                  throws IOException

Description copied from interface: ExternalizableLite

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

Specified by:

readExternal in interface ExternalizableLite

Overrides:

readExternal in class ExtractorFilter<T,E>

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

Description copied from interface: ExternalizableLite

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

Specified by:

writeExternal in interface ExternalizableLite

Overrides:

writeExternal in class ExtractorFilter<T,E>

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 reader)
                  throws IOException

Description copied from interface: PortableObject

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

Specified by:

readExternal in interface PortableObject

Overrides:

readExternal in class ExtractorFilter<T,E>

Parameters:

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

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter writer)
                   throws IOException

Description copied from interface: PortableObject

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

Specified by:

writeExternal in interface PortableObject

Overrides:

writeExternal in class ExtractorFilter<T,E>

Parameters:

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

Throws:

IOException - if an I/O error occurs
