Method Detail

init

public static void init()

Sets up just a single collection of bean instances in the first element of the list. This is useful for clients that are using XMLBeans to load beans.

removeAllBeansFromContainer

public static void removeAllBeansFromContainer(javax.swing.JComponent container,
                                               java.lang.Integer... tab)

Removes all beans from containing component

Parameters:

container - a JComponent value

addAllBeansToContainer

public static void addAllBeansToContainer(javax.swing.JComponent container,
                                          java.lang.Integer... tab)

Adds all beans to the supplied component

Parameters:

container - a JComponent value

getBeanInstances

public static java.util.Vector<java.lang.Object> getBeanInstances(java.lang.Integer... tab)

Return the list of displayed beans

Parameters:

tab - varargs parameter specifying the index of the collection of beans to return - if omitted then the first (i.e. primary) collection of beans is returned

Returns:

a vector of beans

setBeanInstances

public static void setBeanInstances(java.util.Vector<java.lang.Object> beanInstances,
                                    javax.swing.JComponent container,
                                    java.lang.Integer... tab)

Adds the supplied collection of beans at the supplied index in the list of collections. If the index is not supplied then the primary collection is set (i.e. index 0). Also adds the beans to the supplied JComponent container (if not null)

Parameters:

beanInstances - a Vector value

container - a JComponent value

addBeanInstances

public static void addBeanInstances(java.util.Vector<java.lang.Object> beanInstances,

Parameters:

beanInstances - the vector of bean instances to add

container -

removeBeanInstances

public static void removeBeanInstances(javax.swing.JComponent container,
