org.jboss.windup.config.ruleprovider

Class IteratingRuleProvider<PAYLOADTYPE extends WindupVertexFrame>

java.lang.Object

org.ocpsoft.rewrite.context.ContextBase

org.jboss.windup.config.AbstractRuleProvider

org.jboss.windup.config.ruleprovider.IteratingRuleProvider<PAYLOADTYPE>

All Implemented Interfaces:

RuleProvider, org.ocpsoft.common.pattern.Specialized<Object>, org.ocpsoft.common.pattern.Weighted, org.ocpsoft.rewrite.config.ConfigurationProvider<RuleLoaderContext>, org.ocpsoft.rewrite.context.Context

public abstract class IteratingRuleProvider<PAYLOADTYPE extends WindupVertexFrame>
extends AbstractRuleProvider

This provides a simplified way to extend AbstractRuleProvider for cases where the rule simply needs to provide some query, and wants to execute a function over each resulting row.

Description copied from interface: RuleProvider

KEEP - The purpose of this override is to make sure that reflection (interface.getClass().getMethods()) keeps a method with the specific type. Otherwise, type erasure will get rid of it and callers will get ClassCastExceptions in some obscure cases.
