Constructor Detail

BuildExecutionApplicator

public BuildExecutionApplicator(RuntimeEnvironment environment,
                                RuleExecutionContext context,
                                RuleBodyExecutor executor)

Creates the applicator.

Parameters:

environment - the actual runtime environment

context - the actual rule execution context

executor - the actual rule executor

Method Detail

apply

public void apply(java.lang.Object expectedLhsValue,
                  java.lang.Object rhsValue,
                  int index)
           throws VilException

Description copied from class: Applicator

Apply this applicator for one combination which requires building. This may be due to the fact that rhsValue

• is newer than expectedLhsValue
• exists but expectedLhsValue does not exist
• exists but no LHS is specified (expectedLhsValue is null)

Specified by:

apply in class Applicator

Parameters:

expectedLhsValue - the expected result after building rhsValue (may be null)

rhsValue - the value determined for the right side as part of a match

index - the 0-based index of the RHS match condition in the specifying rule (Applicator.getElementCount()

Throws:

VilException - in case that executing parts of a rule or setting variable values fails

getStatus

public RuleExecutionResult.Status getStatus()

Returns the status of the execution.

Returns:

the status

stopMatchLoop

public boolean stopMatchLoop()

Description copied from class: Applicator

Enables a pre-exit of the match loop.

Overrides:

stopMatchLoop in class Applicator

Returns:

true if the match loop shall exit before the next iteration, false if the loop shall continue (default)

stopConditionLoop

public boolean stopConditionLoop()

Description copied from class: Applicator

Enables a pre-exit of the condition loop.

Overrides:

stopConditionLoop in class Applicator

Returns:

true if the condition loop shall exit before the next iteration, false if the loop shall continue (default)
