Class MReturnStatementOptimizer

java.lang.Object

com.massa.mrules.optimizer.AbstractOptimizer

com.massa.mrules.optimizer.AbstractRecursiveOptimizer

com.massa.mrules.optimizer.MReturnStatementOptimizer

All Implemented Interfaces:

IMOptimizer

public class MReturnStatementOptimizer
extends AbstractRecursiveOptimizer

Optimizer which will check that return statements are at the end of a list of executable addons.
Applies for parents which ids are in the "appliesToIds" property.
This optimizer has parameters :

• blocking: if true, throws an Exception if return statements are invalid. Otherwise deletes the following addons. Default is true.
• appliesToIds: ids of parents to analyse.

Since:

2.0.0

Method Detail

pOptimize

protected void pOptimize(ICompilationContext ctxt,
                         IAddon addon)
                  throws MRuleValidationException

Description copied from class: AbstractRecursiveOptimizer

Intermediate method between optimizer's entry point and recursive method, allowing for example to implement easily multi-pass optimizers. Default implementation simply redirects to recursive method.

Overrides:

pOptimize in class AbstractRecursiveOptimizer

Throws:

MRuleValidationException

doBeforeChildren

protected IAddon doBeforeChildren(ICompilationContext ctxt,
                                  IAddon parent,
                                  PersistantPropertyInfo parentProp,
                                  IAddon addon)
                           throws MRuleValidationException

Does nothing.

Specified by:

doBeforeChildren in class AbstractRecursiveOptimizer

Returns:

A new addon instance if the addon should be replaced in the parent. Null if not.

Throws:

MRuleValidationException

doAfterChildren

protected IAddon doAfterChildren(ICompilationContext ctxt,
                                 IAddon parent,
                                 PersistantPropertyInfo parentProp,
                                 IAddon addon)
                          throws MRuleValidationException

Does nothing.

Specified by:

doAfterChildren in class AbstractRecursiveOptimizer

Returns:

A new addon instance if the addon should be replaced in the parent. Null if not.

Throws:

MRuleValidationException

pOptimizeInCollection

protected void pOptimizeInCollection(ICompilationContext ctxt,
                                     IAddon parent,
                                     PersistantPropertyInfo parentProp,
                                     Collection<Object> propValues)
                              throws MRuleValidationException

Checks the addons collection to check that the return statement is in last position.
If blocking, an Exception is thrown.
If not, the addons following the return statement are deleted.

Overrides:

pOptimizeInCollection in class AbstractRecursiveOptimizer

Throws:

MRuleValidationException
