public static EventPropertyGetterSPI getGetter(Method method,
 EventBeanTypedEventFactory eventBeanTypedEventFactory,
 BeanEventTypeFactory beanEventTypeFactory)

Return getter for the given method.

Parameters:

method - to return getter for

eventBeanTypedEventFactory - factory for event beans and event types

beanEventTypeFactory - bean facory

Returns:

property getter

getProperties

public static List<PropertyStem> getProperties(Class clazz)

Introspects the given class and returns event property descriptors for each property found in the class itself, it's superclasses and all interfaces this class and the superclasses implements.

Parameters:

clazz - is the Class to introspect

Returns:

list of properties

getWritableProperties

public static Set<WriteablePropertyDescriptor> getWritableProperties(Class clazz)

Introspects the given class and returns event property descriptors for each writable property found in the class itself, it's superclasses and all interfaces this class and the superclasses implements.

Parameters:

clazz - is the Class to introspect

Returns:

list of properties

removeJavaProperties

public static void removeJavaProperties(List<PropertyStem> properties)

Remove Java language specific properties from the given list of property descriptors.

Parameters:

properties - is the list of property descriptors

removeDuplicateProperties

protected static void removeDuplicateProperties(List<PropertyStem> properties)

Removed duplicate properties using the property name to find unique properties.

Parameters:

properties - is a list of property descriptors

addIntrospectProperties

protected static void addIntrospectProperties(Class clazz,
 List<PropertyStem> result)

Adds to the given list of property descriptors the properties of the given class using the Introspector to introspect properties. This also finds array and indexed properties.

Parameters:

clazz - to introspect

result - is the list to add to

addMappedProperties

protected static void addMappedProperties(Class clazz,
 List<PropertyStem> result)

Adds to the given list of property descriptors the mapped properties, ie. properties that have a getter method taking a single String value as a parameter.

Parameters:

clazz - to introspect

result - is the list to add to

introspect

protected static PropertyDescriptor[] introspect(Class clazz)

Using the Java Introspector class the method returns the property descriptors obtained through introspection.

Parameters:

clazz - to introspect

Returns:

array of property descriptors

getGetterMethodName

public static String getGetterMethodName(String propertyName)

getSetterMethodName

public static String getSetterMethodName(String propertyName)

getIsMethodName

public static String getIsMethodName(String propertyName)
