All Implemented Interfaces:

ParseNode

public class TailActualsNode

extends MinimLParseNode

Represents an actual parameter within the actual parameter list of a tail call (a function call that is the last thing the caller does). A little more precisely, a TailActualsNode represents the head node in the actual parameter list, which contains one actual parameter expression and a reference to the remainder of the list.

Constructor Summary

TailActualsNode(MinimLParseNode actual, MinimLParseNode next)
Initialize a tail call's actual parameter node from the actual parameter expression and the list of actuals that follow it.

Method Summary

void	acceptVisit(MinimLParseVisitor visitor) Allow a visitor object to process a tail call's actual parameter list.
MinimLParseNode	getActual() Retrieve the actual parameter expression from a tail call actual parameter node.
MinimLParseNode	getNext() Retrieve the tail of a tail call's actual parameter list.
void	setActual(MinimLParseNode newActual) Change the actual parameter expression contained in a tail call's actual parameter node.
java.lang.String	toString() Generate a string representation of a tail call's actual parameter list.

Constructor Detail

TailActualsNode

public TailActualsNode(MinimLParseNode actual,
                       MinimLParseNode next)

Initialize a tail call's actual parameter node from the actual parameter expression and the list of actuals that follow it.

Parameters:

actual - The root of the syntax tree for the actual parameter expression.

next - The next actual parameter node in the parameter list.

Method Detail

getActual

public MinimLParseNode getActual()

Retrieve the actual parameter expression from a tail call actual parameter node.

Returns:

The root of the syntax tree for the actual parameter expression.

setActual

public void setActual(MinimLParseNode newActual)

Change the actual parameter expression contained in a tail call's actual parameter node.

Parameters:

newActual - The root of the syntax tree for the new actual parameter expression.

getNext

public MinimLParseNode getNext()

Retrieve the tail of a tail call's actual parameter list.

Returns:

The actual parameter node for the second (and thus subsequent) nodes in the actual parameter list.

acceptVisit

public void acceptVisit(MinimLParseVisitor visitor)
                 throws CompilerException

Allow a visitor object to process a tail call's actual parameter list. Exactly what the visitor does to the list is up to the visitor.

Overrides:

acceptVisit in class MinimLParseNode

Parameters:

visitor - The visitor object that wishes to process the parameter list.

Throws:

CompilerException - If thrown by the visitor.

toString

public java.lang.String toString()

Generate a string representation of a tail call's actual parameter list.

Overrides:

toString in class java.lang.Object

Returns:

A string that identifies a syntax tree node as the head of an actual parameter list.
