Method Detail

• public void addMetaBeanProperty(MetaBeanProperty mp)

  Adds a new MetaBeanProperty to this MetaClass

  Parameters:

  mp - The MetaBeanProperty

• public void addMetaMethod(MetaMethod method)

  adds a MetaMethod to this class. WARNING: this method will not do the neccessary steps for multimethod logic and using this method doesn't mean, that a method added here is replacing another method from a parent class completely. These steps are usually done by initialize, which means if you need these steps, you have to add the method before running initialize the first time.

  Parameters:

  method - the MetaMethod

  See Also:

  initialize()

• protected void addMetaMethodToIndex(MetaMethod method, Header header)

• public void addNewInstanceMethod(Method method)

• public void addNewStaticMethod(Method method)

• protected void applyPropertyDescriptors(PropertyDescriptor[] propertyDescriptors)

• protected final void checkIfGroovyObjectMethod(MetaMethod metaMethod)

  Checks if the metaMethod is a method from the GroovyObject interface such as setProperty, getProperty and invokeMethod

  Parameters:

  metaMethod - The metaMethod instance

  See Also:

  GroovyObject

• protected void checkInitalised()

  checks if the initialisation of the class id complete. This method should be called as a form of assert, it is no way to test if there is still initialisation work to be done. Such logic must be implemented in a different way.

  throws:

  IllegalStateException if the initialisation is incomplete yet

• protected Object chooseMethod(String methodName, Object methodOrList, Class[] arguments)

  Chooses the correct method to use from a list of methods which match by name.

  Parameters:

  methodOrList - the possible methods to choose from

  arguments

• protected void clearInvocationCaches()

  remove all method call cache entries. This should be done if a method is added during runtime, but not by using a category.

  todo there is no CompileUnit in scope so class name checking won't work but that mostly affects the bytecode generation rather than viewing the AST
