Method Detail

computeConstantExpression

public java.lang.Object computeConstantExpression(PsiElement expression)

Description copied from class: PsiConstantEvaluationHelper

Evaluates the value of the specified expression.

Overrides:

computeConstantExpression in class PsiConstantEvaluationHelper

Parameters:

expression - the expression to evaluate.

Returns:

the result of the evaluation, or null if the expression is not a constant expression.

                                                  boolean throwExceptionOnOverflow)

Description copied from class: PsiConstantEvaluationHelper

Evaluates the value of the specified expression and optionally throws ConstantEvaluationOverflowException if an overflow is detected during the evaluation.

Specified by:

computeConstantExpression in class PsiConstantEvaluationHelper

Parameters:

expression - the expression to evaluate.

throwExceptionOnOverflow - if true, an exception is thrown if an overflow is detected during the evaluation.

Returns:

the result of the evaluation, or null if the expression is not a constant expression.
