public class IdentifierExpr

extends Expr

implements IdentifierExpression

This node represents an identifier expression. Examples of identifier expressions are FieldAccessExpression, ParameterAccessExpression, ThisExpressionor VariableAccessExpression. This class is not defined abstract to allow the syntactical analysis to construct general nodes, which are replaced by the semantic analysis with their specialized counterparts.

Constructor Detail

IdentifierExpr

public IdentifierExpr()

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.

IdentifierExpr

public IdentifierExpr(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.

IdentifierExpr

IdentifierExpr(int tokenType,
               java.lang.String name,
               java.lang.Class clazz)

This constructor is called by specialized nodes. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.

Parameters:

tokenType - the token type

name - the name of this identifier

clazz - the Java type of this identifier

Method Detail

getName

public java.lang.String getName()

Returns the name of the specialized identifier.

Specified by:

getName in interface IdentifierExpression

Returns:

the name

getTypeName

public java.lang.String getTypeName()

Returns the Java type name of the specialized identifier.

Specified by:

getTypeName in interface IdentifierExpression

Returns:

the Java type name

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
