Modifier and Type	Method and Description
AbstractMathOperator	clone() Clones the Addon.
void	compile(ICompilationContext ctxt, IReadAccessor left, IReadAccessor right) Does nothing except logging in basic implementation
protected void	compileOperator(ICompilationContext ctxt, IReadAccessor left, IReadAccessor right) Does nothing in basic implementation
protected abstract BigDecimal	compute(BigDecimal nleft, BigDecimal nright)
Number	compute(IExecutionContext ctxt, IReadAccessor left, IReadAccessor right) Evaluate result for this operator.
protected abstract int	compute(int nleft, int nright)
protected abstract long	compute(long nleft, long nright)
protected Number	compute(Number nleft, Number nright) Chooses between compute implementations.
boolean	equals(Object o)
protected boolean	forceUseOfBigDecimal()
int	hashCode()
protected Number	redirectToBigDecimal(Number nleft, Number nright) If no specific applicable implem of compute has been found, this method is called and default implem redirects to BigDecimal computation.

compile

public final void compile(ICompilationContext ctxt,
                          IReadAccessor left,
                          IReadAccessor right)
                   throws MRuleValidationException

Does nothing except logging in basic implementation

Specified by:

compile in interface IMathOperator

left - If known, left operand. If unknown, null value is handled.

right - If known, right operand. If unknown, null value is handled.

Throws:

MRuleValidationException

compute

public Number compute(IExecutionContext ctxt,
                      IReadAccessor left,
                      IReadAccessor right)
               throws MAccessorException

Description copied from interface: IMathOperator

Evaluate result for this operator.

Specified by:

compute in interface IMathOperator

Throws:

MAccessorException

compute

protected Number compute(Number nleft,
                         Number nright)
                  throws MAccessorException
