Constructor Detail

CandidateClassImpl

public CandidateClassImpl()
The noarg constructor is needed for ANTLR support and deserialization. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.


CandidateClassImpl

public CandidateClassImpl(antlr.Token token)
The noarg constructor is needed for ANTLR support. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.

Method Detail

setCandidateClass

public void setCandidateClass(java.lang.Class clazz)
Sets the candidate class for this instance. This method is used by semantic analysis only.

clazz - the candidate clazz

arrive

public void arrive(NodeVisitor visitor)
Delegates to the argument visitor.

Specified by:
arrive in interface Node
Overrides:
arrive in class NodeImpl
Parameters:
visitor - the node visitor

leave

public java.lang.Object leave(NodeVisitor visitor,
                              java.lang.Object[] results)
Delegates to the argument visitor.

Specified by:
leave in interface Node
Overrides:
leave in class NodeImpl
Parameters:
visitor - the node visitor
results - the result array
Returns:
the object returned by the visitor instance
