Method Detail

addMetaBeanProperty

public void addMetaBeanProperty(MetaBeanProperty mp)

addMetaMethod

public void addMetaMethod(MetaMethod method)
Returns:
the matching method which should be found

checkIfGroovyObjectMethod

protected final void checkIfGroovyObjectMethod(MetaMethod metaMethod)
Chooses the correct method to use from a list of methods which match by name.
Parameters:
methodOrList - the possible methods to choose from
arguments

checkInitalised

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
