Constructors in java.beans that throw IntrospectionException
Modifier
Constructor
Description
``
`EventSetDescriptor(Class<?> sourceClass, String eventSetName, Class<?> listenerType, String listenerMethodName)`
Creates an `EventSetDescriptor` assuming that you are following the most simple standard design pattern where a named event "fred" is (1) delivered as a call on the single method of interface FredListener, (2) has a single argument of type FredEvent, and (3) where the FredListener may be registered with a call on an addFredListener method of the source component and removed with a call on a removeFredListener method.
``
`EventSetDescriptor(Class<?> sourceClass, String eventSetName, Class<?> listenerType, String[] listenerMethodNames, String addListenerMethodName, String removeListenerMethodName)`
Creates an `EventSetDescriptor` from scratch using string names.
``
`EventSetDescriptor(Class<?> sourceClass, String eventSetName, Class<?> listenerType, String[] listenerMethodNames, String addListenerMethodName, String removeListenerMethodName, String getListenerMethodName)`
This constructor creates an EventSetDescriptor from scratch using string names.
``
`EventSetDescriptor(String eventSetName, Class<?> listenerType, MethodDescriptor[] listenerMethodDescriptors, Method addListenerMethod, Method removeListenerMethod)`
Creates an `EventSetDescriptor` from scratch using `java.lang.reflect.MethodDescriptor` and `java.lang.Class` objects.
``
`EventSetDescriptor(String eventSetName, Class<?> listenerType, Method[] listenerMethods, Method addListenerMethod, Method removeListenerMethod)`
Creates an `EventSetDescriptor` from scratch using `java.lang.reflect.Method` and `java.lang.Class` objects.
``
`EventSetDescriptor(String eventSetName, Class<?> listenerType, Method[] listenerMethods, Method addListenerMethod, Method removeListenerMethod, Method getListenerMethod)`
This constructor creates an EventSetDescriptor from scratch using java.lang.reflect.Method and java.lang.Class objects.
``
`IndexedPropertyDescriptor(String propertyName, Class<?> beanClass)`
This constructor constructs an IndexedPropertyDescriptor for a property that follows the standard Java conventions by having getFoo and setFoo accessor methods, for both indexed access and array access.
``
`IndexedPropertyDescriptor(String propertyName, Class<?> beanClass, String readMethodName, String writeMethodName, String indexedReadMethodName, String indexedWriteMethodName)`
This constructor takes the name of a simple property, and method names for reading and writing the property, both indexed and non-indexed.
``
`IndexedPropertyDescriptor(String propertyName, Method readMethod, Method writeMethod, Method indexedReadMethod, Method indexedWriteMethod)`
This constructor takes the name of a simple property, and Method objects for reading and writing the property.
``
`PropertyDescriptor(String propertyName, Class<?> beanClass)`
