Method Detail

compileOperator

protected void compileOperator(ICompilationContext ctxt,
                               IEvaluationCondition condition)
                        throws MRuleValidationException

Description copied from class: AbstractEvaluationOperator

Does nothing in basic implementation

Overrides:

compileOperator in class AbstractEvaluationOperator

Throws:

MRuleValidationException

evaluate

public boolean evaluate(IExecutionContext ctxt,
                        IEvaluationCondition condition)
                 throws MConditionEvaluationException

Description copied from interface: IEvaluationOperator

Evaluate result for this operator.

Throws:

MConditionEvaluationException

getInverted

public IEvaluationOperator getInverted()

Description copied from interface: IEvaluationOperator

Returns a new instance instance of Evaluation operator, allowing to invert the operands.
For example, "a < b" inverted gives "b > a", and is strictly equivalent.
This feature is used by optimization process, so a null result by default while the operator could be inverted might lead to less efficient performance.

Returns:

new operator instance or null if inversion is not possible.

getNegated

public IEvaluationOperator getNegated()

Description copied from interface: IEvaluationOperator

Returns a new instance instance of Evaluation operator, allowing to negate the operands.
For example, "a < b" negated gives "a >= b", and is strictly equivalent to "! (a < b)". This feature is used by optimization process, so a null result by default while the operator could be negated might lead to less efficient performance.

Returns:

new operator instance or null if negation is not possible.

getRepresentation

public String getRepresentation()

Description copied from interface: IEvaluationOperator

String representation for human read

getImplementationId

public String getImplementationId()

Description copied from interface: IAddon

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

toString

public void toString(OuterWithLevel outer)
              throws IOException

Description copied from interface: Outable

Method used to send String representation of the current object to the OuterWithLevel.

Specified by:

toString in interface Outable

Overrides:

toString in class AbstractEvaluationOperator

Throws:

IOException

getSourceExpectedType

public Class<?> getSourceExpectedType()

Description copied from class: AbstractEvaluationOperator

Returns null in basic implementation.

Specified by:

getSourceExpectedType in interface IEvaluationOperator

Overrides:

getSourceExpectedType in class AbstractEvaluationOperator

getReferenceExpectedType

public Class<?> getReferenceExpectedType(Class<?> srcType,
                                         Class<?> srcGenericType)

Description copied from class: AbstractEvaluationOperator

Returns null in basic implementation.

Specified by:

getReferenceExpectedType in interface IEvaluationOperator

Overrides:

getReferenceExpectedType in class AbstractEvaluationOperator

Parameters:

srcType - If known, the source accessor type should be provided to make better prevision.

srcGenericType - If known, the source accessor generic type should be provided to make better prevision.

clone

public BETWEEN clone()

Description copied from interface: IAddon

Clones the Addon.
The general contract is that the clone of a compiled Addon is still compiled.

Specified by:

clone in interface IAddon

Specified by:

clone in interface IMRulesObject

Specified by:

clone in interface IEvaluationOperator

Overrides:

clone in class AbstractEvaluationOperator

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractEvaluationOperator

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractEvaluationOperator

getMin

public IReadAccessor getMin()

setMin

public void setMin(IReadAccessor min)

getMax

public IReadAccessor getMax()

setMax

public void setMax(IReadAccessor max)
