is

greater

eqv

public boolean eqv(java.lang.Object v)

Description copied from class: Value

Compares this Value to another for equality according to the rules of Scheme's eqv?. In SISC, this differs from eq? in that eq? is strict pointer equality.

Overrides:

eqv in class Value

Parameters:

v - the other Value

equals

public boolean equals(java.lang.Object v)

Description copied from class: Value

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

Overrides:

equals in class Value

Parameters:

v - the other Value

valueEqual

public boolean valueEqual(Value v)

Description copied from class: Value

Compares this value to another for semantic equality. Used to implement Scheme's 'equal?'. Subclasses must test for pointer equality as well as semantic equality, so that infinite loops on recursive structures are less likely.

Overrides:

valueEqual in class Value

Parameters:

v - the other Value

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

display

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

Specified by:

display in class Value

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class Value

zeroTrim

protected static java.lang.String zeroTrim(java.lang.String s)

toString

public java.lang.String toString(int radix)

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

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

singletonValue

public Value singletonValue()

Specified by:

singletonValue in interface Singleton
