All Implemented Interfaces:

IAddon, IMRulesObject, ICondition, Outable, Serializable, Cloneable

public class MHardCodedCondition
extends AbstractCondition

This implementation allows to specify a condition with a constant result.
It's mainly intended for internal optimization.

Constructor Detail

MHardCodedCondition

public MHardCodedCondition()

MHardCodedCondition

public MHardCodedCondition(boolean val)

Method Detail

getImplementationId

public String getImplementationId()

Description copied from interface: IAddon

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

compile

public void compile(ICompilationContext ctxt)
             throws MRuleValidationException

Description copied from interface: ICondition

Compiles condition and validates data.

Throws:

MRuleValidationException - if validation problem detected.

getEstimatedCost

public CostInfo getEstimatedCost(ICompilationContext ctxt)

Description copied from interface: ICondition

Estimates the condition complexity, to allow callers to optimize calls. Calls to this method should be done on a compiled condition, so that all information is available to compute complexity.
Calls to non-compiled instance may return non-accurate results.

isConstantValue

public boolean isConstantValue()

Description copied from interface: ICondition

Tells if this condition returns a constant result for all executions.

isShouldBeWrappedToConstantValue

public boolean isShouldBeWrappedToConstantValue()

Description copied from class: AbstractCondition

Default implementation returns ICondition.isConstantValue().

Specified by:

isShouldBeWrappedToConstantValue in interface ICondition

Overrides:

isShouldBeWrappedToConstantValue in class AbstractCondition

pEvaluate

protected boolean pEvaluate(IExecutionContext ctxt)
                     throws MConditionEvaluationException

Specified by:

pEvaluate in class AbstractCondition

Throws:

MConditionEvaluationException

pEquals

protected boolean pEquals(AbstractCondition o)

Description copied from class: AbstractCondition

Tests equality on other parameters than "not".

Specified by:

pEquals in class AbstractCondition

pHashCode

protected int pHashCode()

Description copied from class: AbstractCondition

Computes hashCode on other parameters than "not".

Specified by:

pHashCode in class AbstractCondition

clone

public MHardCodedCondition 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 ICondition

Overrides:

clone in class AbstractCondition

pToString

protected void pToString(OuterWithLevel outer)
                  throws IOException

Description copied from class: AbstractCondition

Finishes toString output.

Specified by:

pToString in class AbstractCondition

Throws:

IOException

isCacheUsed

public boolean isCacheUsed()

Description copied from class: AbstractAddon

Returns false by default.

Specified by:

isCacheUsed in interface IAddon

Overrides:

isCacheUsed in class AbstractAddon

internalIsEquivalent

protected ConditionEquivalence internalIsEquivalent(ICondition o)

Description copied from class: AbstractCondition

Called by AbstractCondition.internalIsEquivalent(ICondition) if the other condition is not an instance of MConditionNot.

Specified by:

internalIsEquivalent in class AbstractCondition

isVal

public boolean isVal()

setVal

public void setVal(boolean val)
