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

Overrides:

apply in class AbstractPredicate

Parameters:

mapEntry - the map entry to apply this predicate to.

Returns:

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

applyForSingleAttributeValue

protected boolean applyForSingleAttributeValue(Comparable attributeValue)

Specified by:

applyForSingleAttributeValue in class AbstractPredicate

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

Overrides:

writeData in class AbstractPredicate

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

Overrides:

readData in class AbstractPredicate

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.

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractPredicate

canEqual

public boolean canEqual(Object other)

Overrides:

canEqual in class AbstractPredicate

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractPredicate

toString

public String toString()

Overrides:

toString in class Object

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.

getClassId

public int getClassId()

Description copied from interface: IdentifiedDataSerializable

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

Specified by:

getClassId in interface IdentifiedDataSerializable

Returns:

type ID
