Field Detail

operation

public Operator operation

(¬ø) The binary operation.

left

public ConstraintExpression left

(¬ø) The left hand side of the binary expression.

right

public ConstraintExpression right

(¬ø) The right hand side of the binary expression.

Constructor Detail

BinaryConstraintExpression

public BinaryConstraintExpression(Operator op,
                                  ConstraintExpression l,
                                  ConstraintExpression r)

Initializing constructor. Line and byte offset information are taken from the representation of the operator.

Parameters:

op - Reference to the operator's representation.

l - Reference to the left hand side's representation.

r - Reference to the right hand side's representation.

Method Detail

iterator

public ASTNodeIterator iterator()

Returns an iterator used to successively access the children of this node.

Specified by:

iterator in class ASTNode

Returns:

An iterator used to successively access the children of this node.

clone

public Object clone()

Creates a new object with the same primitive data, and recursively creates new member data objects as well.

Overrides:

clone in class ASTNode

Returns:

The clone node.

runPass

public void runPass(Pass pass)

Ensures that the correct run() method is called for this type of node.

Specified by:

runPass in class ASTNode

Parameters:

pass - The pass whose run() method should be called.

write

public void write(StringBuffer buffer)

Writes a string representation of this ASTNode to the specified buffer. The representation written is parsable by the LBJava compiler, but not very readable.

Specified by:

write in class ASTNode

Parameters:

buffer - The buffer to write to.
