Method Detail

display

public void display(ValueWriter w)
             throws java.io.IOException

Specified by:

display in class Value

Throws:

java.io.IOException

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Description copied from class: Value

Compares this Value to another. By default equal to eqv.

Overrides:

equals in class Value

Parameters:

o - the other Value

serialize

public void serialize(Serializer s)
               throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to be serialized to a heap must implement both this and the deserialize method. The Expression may use any method of the Serializer, which implements java.io.DataOutput to write its state.

Overrides:

serialize in class Expression

Parameters:

s - the Serializer

Throws:

java.io.IOException

deserialize

public void deserialize(Deserializer s)
                 throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to b serialized to a heap must implement both this and the serialize method. The Expression may use any method of the DataInput stream and the Deserializer serialization context to read its state.

Overrides:

deserialize in class Expression

Parameters:

s - the Deserializer

Throws:

java.io.IOException

singletonValue

public Value singletonValue()

Specified by:

singletonValue in interface Singleton
