Method Detail

apply

public boolean apply(Map.Entry mapEntry)

Description copied from interface: Predicate

Applies this predicate to the given map entry.

Implementations must be thread-safe, since this method may be called by multiple threads concurrently.

Specified by:

apply in interface Predicate

Parameters:

mapEntry - the map entry to apply this predicate to.

Returns:

true if the given map entry matches this predicate, false otherwise.

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.

toString

public String toString()

Overrides:

toString in class Object

accept

public Predicate accept(Visitor visitor,
                        Indexes indexes)

Description copied from interface: VisitablePredicate

Accept visitor. Predicate can either return it's own instance if no modification was done as a result of the visit. In the case there is a change needed then the predicate has to return changed copy of itself. Predicates has to be treated as immutable for optimization purposes.

Specified by:

accept in interface VisitablePredicate

Parameters:

visitor - visitor to accept

indexes - indexes

Returns:

itself or its changed copy

negate

public Predicate negate()

Description copied from interface: NegatablePredicate

Create logical negation of itself.

Specified by:

negate in interface NegatablePredicate

Returns:

A predicate which is a logical negation of itself.

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
