Constructor Detail

ParameterAccessExpr

public ParameterAccessExpr()
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.


ParameterAccessExpr

public ParameterAccessExpr(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.


ParameterAccessExpr

ParameterAccessExpr(java.lang.Class clazz,
                    java.lang.String name)
This constructor is called by the query tree instance. It delegates to the super class constructor.

Parameters:
clazz - the Java type of this identifier
name - the name of this identifier
Method Detail

arrive

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

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