Methods Summary
public java.lang.Object	evaluate(java.lang.Object pContext, VariableResolver pResolver, java.util.Map functions, java.lang.String defaultPrefix, Logger pLogger) Evaluates to the literal value Object value = mExpression.evaluate (pContext, pResolver, functions, defaultPrefix, pLogger); if (mOperator != null) { value = mOperator.apply (value, pContext, pLogger); } else { for (int i = mOperators.size () - 1; i >= 0; i--) { UnaryOperator operator = (UnaryOperator) mOperators.get (i); value = operator.apply (value, pContext, pLogger); } } return value;
public Expression	getExpression() return mExpression;
public java.lang.String	getExpressionString() Returns the expression in the expression language syntax StringBuffer buf = new StringBuffer (); buf.append ("("); if (mOperator != null) { buf.append (mOperator.getOperatorSymbol ()); buf.append (" "); } else { for (int i = 0; i < mOperators.size (); i++) { UnaryOperator operator = (UnaryOperator) mOperators.get (i); buf.append (operator.getOperatorSymbol ()); buf.append (" "); } } buf.append (mExpression.getExpressionString ()); buf.append (")"); return buf.toString ();
