Method Detail

addClosureCode

protected void addClosureCode(InnerClassNode node)

addConstructor

protected void addConstructor(Parameter[] newParams, ConstructorNode ctor, Statement code, ClassNode node)

addCovariantMethods

protected void addCovariantMethods(ClassNode classNode)

addDefaultConstructor

protected void addDefaultConstructor(ClassNode node)

addDefaultParameterConstructors

protected void addDefaultParameterConstructors(ClassNode node)
Creates a new helper method for each combination of default parameter expressions

addDefaultParameterMethods

protected void addDefaultParameterMethods(ClassNode node)

addDefaultParameters

protected void addDefaultParameters(java.util.List methods, Verifier.DefaultArgsAction action)

addDefaultParameters

protected void addDefaultParameters(Verifier.DefaultArgsAction action, MethodNode method)

addFieldInitialization

protected void addFieldInitialization(java.util.List list, java.util.List staticList, FieldNode fieldNode, boolean isEnumClassNode, java.util.List initStmtsAfterEnumValuesInit, java.util.Set explicitStaticPropsInEnum)

addGroovyObjectInterfaceAndMethods

protected void addGroovyObjectInterfaceAndMethods(ClassNode node, java.lang.String classInternalName)

addInitialization

protected void addInitialization(ClassNode node)

addInitialization

protected void addInitialization(ClassNode node, ConstructorNode constructorNode)

addMethod

protected void addMethod(ClassNode node, boolean shouldBeSynthetic, java.lang.String name, int modifiers, ClassNode returnType, Parameter[] parameters, ClassNode[] exceptions, Statement code)
the code is: if (this.metaClass==null) { this.metaClass = this.$getStaticMetaClass return this.metaClass } else { return this.metaClass } with the optimization that the result of the first this.metaClass is duped on the operand stack and reused for the return in the else part

protected void addPropertyMethod(MethodNode method)

addReturnIfNeeded

protected void addReturnIfNeeded(MethodNode node)

addTimeStamp

protected void addTimeStamp(ClassNode node)

capitalize

public static java.lang.String capitalize(java.lang.String name)
Capitalizes the start of the given bean property name

createGetterBlock
