public class RuleGenerateWith
extends Rule

A rule to replace the type being rebound with a class whose name is determined by a generator class. Generators usually generate new classes during the deferred binding process, but it is not required.

Method Summary

Modifier and Type	Method and Description
boolean	caresAboutProperties(Set<String> propertyNames) Returns whether the output of the Generator being managed by this rule is modified by or whether the rules embedded condition is judging any of the properties whose names have been passed. Makes it possible for external callers to watch the changing property environment and only trigger Generators within Rules whose output might have changed.
boolean	contentDependsOnTypes() Returns whether the output of the Generator being managed by this rule depends on access to the global set of types to be able to run accurately.
boolean	equals(Object obj)
void	generate(TreeLogger logger, Properties moduleProperties, GeneratorContext context, String typeName) Generate all possible Generator output for the wrapped Generator in combination with the scope of Properties and values known about by the passed GeneratorContext.
protected String	generateCreateInstanceExpression() Generate and return a String of Java source that will create an instance of whatever type this Rule intends to rebind to.
protected String	generateMatchesExpression() Generate and return a String of Java source that will act as a condition to filter the runtime environment and only pass when the Rule's intended conditions are met.
static Set<String>	getAccessedPropertyNames(Class<? extends Generator> generatorClass) Returns a Set of the names of properties that will be accessed by the given Generator.
protected Generator	getGenerator()
String	getName() Returns the name of the class of Generator being managed here.

Method Detail

getAccessedPropertyNames

public static Set<String> getAccessedPropertyNames(Class<? extends Generator> generatorClass)

Returns a Set of the names of properties that will be accessed by the given Generator.

caresAboutProperties

public boolean caresAboutProperties(Set<String> propertyNames)

Returns whether the output of the Generator being managed by this rule is modified by or whether the rules embedded condition is judging any of the properties whose names have been passed.
Makes it possible for external callers to watch the changing property environment and only trigger Generators within Rules whose output might have changed.

contentDependsOnTypes

public boolean contentDependsOnTypes()

Returns whether the output of the Generator being managed by this rule depends on access to the global set of types to be able to run accurately.
