Method Detail

compileValue

public void compileValue(ICompilationContext ctxt,
                         Class<?> expectedType)
                  throws MRuleValidationException

Checks that decimals property is present.

Overrides:

compileValue in class MArithmeticAccessor

Throws:

MRuleValidationException

evaluate

                           MArithmeticAccessor.InternalIterator values)
                    throws MAccessorException

Description copied from class: MArithmeticAccessor

Performs the arithmetic operation.

Specified by:

evaluate in class MArithmeticAccessor

Throws:

MAccessorException

lastDivision

protected BigDecimal lastDivision(BigDecimal ret,
                                  BigDecimal bd)

Performs last division, with correct formatting.

shouldFormatResult

protected boolean shouldFormatResult()

Returns false, as Divide formats results by default.

Overrides:

shouldFormatResult in class MArithmeticAccessor

getImplementationId

public String getImplementationId()

Description copied from interface: IAddon

Unique addon implementation ID. In case of conflict, an Class Initialization error will be raised.
