Constructor Details

ListenerConfig

public ListenerConfig()

Creates a ListenerConfig without className/implementation.

ListenerConfig

public ListenerConfig(String className)

Creates a ListenerConfig with the given className.

Parameters:

className - the name of the EventListener class

Throws:

IllegalArgumentException - if className is null or an empty String

ListenerConfig

public ListenerConfig(EventListener implementation)

Creates a ListenerConfig with the given implementation.

Parameters:

implementation - the implementation to use as EventListener

Throws:

IllegalArgumentException - if the implementation is null

ListenerConfig

public ListenerConfig(ListenerConfig config)

Method Details

getClassName

public String getClassName()

Returns the name of the class of the EventListener. If no class is specified, null is returned.

Returns:

the class name of the EventListener

See Also:

• setClassName(String)

setClassName

public ListenerConfig setClassName(@Nonnull
 String className)

Sets the class name of the EventListener.

If an implementation was set, it will be removed.

Parameters:

className - the name of the class of the EventListener

Returns:

the updated ListenerConfig

Throws:

IllegalArgumentException - if className is null or an empty String

See Also:

• setImplementation(java.util.EventListener)
• getClassName()

getImplementation

public EventListener getImplementation()

Returns the EventListener implementation. If none has been specified, null is returned.

Returns:

the EventListener implementation

See Also:

• setImplementation(java.util.EventListener)

setImplementation

public ListenerConfig setImplementation(EventListener implementation)

Sets the EventListener implementation.

If a className was set, it will be removed.

Parameters:

implementation - the EventListener implementation

Returns:

the updated ListenerConfig

Throws:

IllegalArgumentException - the implementation is null

See Also:

• setClassName(String)
• getImplementation()

isIncludeValue

public boolean isIncludeValue()

isLocal

public boolean isLocal()

toString

public String toString()

Overrides:

toString in class Object

getFactoryId
