Method Detail

setup

public static void setup()

registerDialog

public static void registerDialog(java.lang.Class pEntity,
                                  java.lang.Class pDialogClass)

Add a (property) dialog for a given entity

hasDialog

public static boolean hasDialog(java.lang.Class pEntityClass)

Returns true, if a (property) dialog for given class exists. This methos searches not for dialogs of superclasses.

Parameters:

pEntityClass - Class to search for a dialog

Returns:

true, if a dialog exists

hasDialog

public static boolean hasDialog(java.lang.Class pEntityClass,
                                boolean pSearch)

Returns true, if dialog for given class exists. This methos searches not for dialogs of superclasses.

Parameters:

pEntityClass - Class to search for a dialog

pSearch - If true, hasDialog searches also for dialogs of superclasses

Returns:

true, if a dialog exists

instanceExists

public static boolean instanceExists(java.lang.Class pEntityClass)

Checks, if a dialog instance already exists.

Returns:

true, if an instance already exists. In this case you need not pass an argument array to getDialogForClass.

See Also:

getDialogForClass(Class,Object[])

getDialogForClass

public static javax.swing.JDialog getDialogForClass(java.lang.Class pEntityClass,
                                                    java.lang.Object[] pArgs)

Returns the (cached) dialog instance for a given entity class. Some dialogs may expect arguments in their constructor, they can passeg via the pArgs parameter. If an instance already exists, the existing instance is returned. The argument array is not used in this case.

Parameters:

pEntityClass - Class for which a dialog should be created

pArgs - Arguments which should be passed to the dialog constructor

Returns:

Dialog instance or null, if

• No dialog class could be found
• No matching constructor for given arguments could be found
• No instance could be created (see crossreferences below for these issues)

Guesses a constructor for given parameter types
