Method Detail

evaluate

public OwExprValue evaluate(OwExprNumericValue v1_p,
                   OwExprNumericValue v2_p)
                     throws OwExprEvaluationException

Evaluates numeric values using Java's Comparable implementations

Overrides:

evaluate in class OwExprBinaryOperator

Parameters:

v1_p - leftside operand

v2_p - rightside operand

Returns:

a true OwExprBooleanValue if leftside operand is equal to or less than the right side operand

Throws:

OwExprEvaluationException

evaluate

public OwExprValue evaluate(OwExprDateValue v1_p,
                   OwExprDateValue v2_p)
                     throws OwExprEvaluationException

Evaluates date values using Java's Comparable implementations

Overrides:

evaluate in class OwExprBinaryOperator

Parameters:

v1_p - leftside operand

v2_p - rightside operand

Returns:

a true OwExprBooleanValue if leftside date operand is equal to or less than ...

Throws:

OwExprEvaluationException

evaluate

public OwExprValue evaluate(OwExprTimeValue v1_p,
                   OwExprTimeValue v2_p)
                     throws OwExprEvaluationException

Evaluates time values using Java's Comparable implementations

Overrides:

evaluate in class OwExprBinaryOperator

Parameters:

v1_p - leftside operand

v2_p - rightside operand

Returns:

a true OwExprBooleanValue if leftside timespan operand is equal to or less that right side timespan operand

Throws:

OwExprEvaluationException
