C# Class PclUnit.Constraints.Pieces.ConstraintBuilder

ConstraintBuilder maintains the stacks that are used in processing a ConstraintExpression. An OperatorStack is used to hold operators that are waiting for their operands to be reognized. a ConstraintStack holds input constraints as well as the results of each operator applied.

Public Methods

Method	Description
Append ( Constraint constraint ) : void	Appends the specified constraint to the expresson by pushing it on the constraint stack.
Append ( ConstraintOperator op ) : void	Appends the specified operator to the expression by first reducing the operator stack and then pushing the new operator on the stack.
ConstraintBuilder ( ) : System	Initializes a new instance of the T:ConstraintBuilder class.
Resolve ( ) : Constraint	Resolves this instance, returning a Constraint. If the builder is not currently in a resolvable state, an exception is thrown.

Private Methods

Method	Description
ReduceOperatorStack ( int targetPrecedence ) : void	Reduces the operator stack until the topmost item precedence is greater than or equal to the target precedence.
SetTopOperatorRightContext ( object rightContext ) : void	Sets the top operator right context.
