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.

Specified by:

serialize in interface SymbolicEnvironment

Overrides:

serialize in class Expression

Parameters:

s - the Serializer

Throws:

java.io.IOException

serializeSidecar

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

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.

Specified by:

deserialize in interface SymbolicEnvironment

Overrides:

deserialize in class Expression

Parameters:

s - the Deserializer

Throws:

java.io.IOException

deserializeSidecar

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

Throws:

java.io.IOException

visit

public boolean visit(ExpressionVisitor v)

Specified by:

visit in interface ExpressionVisitee

Overrides:

visit in class Expression

visitSidecar

public boolean visitSidecar(ExpressionVisitor v)
