Constructor Detail

UnaryOperatorExpression

public UnaryOperatorExpression(java.lang.String operator,
                               TypedExpression baseExpression)
Creates a UnaryOperatorExpression that represents the operation specified by the unary operator upon the base expression.
Parameters:
operator - The constant of this class, which iss UnaryOperatorExpression.MINUS.
baseExpression - A TypedExpression upon which the unary operator acts.

Method Detail

visit

public java.lang.Object visit(SyntaxObjectVisitor visitor,
                              java.lang.Object context)

Specified by:
visit in class SyntaxObject
Parameters:
visitor - A SyntaxObjectVisitor.
context - An Object.
Returns:
The Object returned by the visitUnaryOperatorExpression method.

getOperator

public java.lang.String getOperator()
Gets the operator that is associated with this UnaryOperatorExpression.
Returns:
A String that contains the operator of this UnaryOperatorExpression.

getBaseExpression

public TypedExpression getBaseExpression()
Gets the base expression of this UnaryOperatorExpression.
Returns:
A String that contains the base expression of this UnaryOperatorExpression.
