Field Detail

constraint

public ConstraintExpression constraint

(¬ø) The expression representing the constraint.

Constructor Detail

ConstraintStatementExpression

public ConstraintStatementExpression(ConstraintExpression c)

Full constructor. Line and byte offset information is taken from the lone argument.

Parameters:

c - The expression representing a constraint.

Method Detail

getVariableTypes

public HashSet<Argument> getVariableTypes()

Returns a set of Arguments storing the name and type of each variable that is a subexpression of this expression. This method cannot be run before SemanticAnalysis runs.

Overrides:

getVariableTypes in class Expression

containsQuantifiedVariable

public boolean containsQuantifiedVariable()

Determines if there are any quantified variables in this expression. This method cannot be run before SemanticAnalysis runs.

Overrides:

containsQuantifiedVariable in class Expression

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.
