Constructor Detail

LEqNode

public LEqNode(MinimLParseNode left,
               MinimLParseNode right)

Initializes a less-than-or-equal node.

Parameters:

left - The root of the syntax tree for the left operand.

right - The root of the syntax tree for the right operand.

Method Detail

getLeft

public MinimLParseNode getLeft()

Retrieve the left operand of a less-than-or-equal node.

Returns:

The root of the syntax tree for the left operand.

setLeft

public void setLeft(MinimLParseNode newLeft)

Change a less-than-or-equal node's left operand.

Parameters:

newLeft - The root of the syntax tree for the new left operand.

getRight

public MinimLParseNode getRight()

Retrieve a less-than-or-equal node's right operand.

Returns:

The root of the syntax tree for the right operand.

setRight

public void setRight(MinimLParseNode newRight)

Change a less-than-or-equal node's right operand.

Parameters:

newRight - The root of the syntax tree for the new right operand.

acceptVisit

public void acceptVisit(MinimLParseVisitor visitor)
                 throws CompilerException

Allow a visitor object to process a less-than-or-equal node in some way. Exactly how the visitor processes the node is up to the visitor.

Overrides:

acceptVisit in class MinimLParseNode

Parameters:

visitor - The visitor object that wishes to process the comparison node.

Throws:

CompilerException - If thrown by the visitor.

toString

public java.lang.String toString()

Generate a string representation of a less-than-or-equal node.

Overrides:

toString in class java.lang.Object

Returns:

A string that indicates the presence of a less-than-or-equal comparison.
