Constructor for OjbMetaCollectionDescriptorNode

Method Detail

_load

protected boolean _load()

Description copied from class: OjbMetaTreeNode

Purpose of this method is to fill the children of the node. It should replace all children in alChildren (the arraylist containing the children) of this node and notify the TreeModel that a change has occurred.

Specified by:

_load in class OjbMetaTreeNode

See Also:

OjbMetaTreeNode._load()

isLeaf

public boolean isLeaf()

Specified by:

isLeaf in interface javax.swing.tree.TreeNode

Specified by:

isLeaf in class OjbMetaTreeNode

See Also:

OjbMetaTreeNode.isLeaf()

getAllowsChildren

public boolean getAllowsChildren()

Specified by:

getAllowsChildren in interface javax.swing.tree.TreeNode

Specified by:

getAllowsChildren in class OjbMetaTreeNode

See Also:

OjbMetaTreeNode.getAllowsChildren()

setAttribute

public void setAttribute(java.lang.String strKey,
                         java.lang.Object value)

Description copied from class: EditableTreeNodeWithProperties

Set an attribute of this node as Object. This method is backed by a HashMap, so all rules of HashMap apply to this method. Fires a PropertyChangeEvent.

Specified by:

setAttribute in interface PropertyEditorTarget

Overrides:

setAttribute in class EditableTreeNodeWithProperties

See Also:

EditableTreeNodeWithProperties.setAttribute(String, Object)

getAttribute

public java.lang.Object getAttribute(java.lang.String strKey)

Description copied from class: EditableTreeNodeWithProperties

Get an attribute of this node as Object. This method is backed by a HashMap, so all rules of HashMap apply to this method.

Specified by:

getAttribute in interface PropertyEditorTarget

Overrides:

getAttribute in class EditableTreeNodeWithProperties

See Also:

EditableTreeNodeWithProperties.getAttribute(String)

getPropertyEditorClass

public java.lang.Class getPropertyEditorClass()

Description copied from interface: PropertyEditorTarget

Return the property editor class for this PropertyEditorTarget. Depending on the GUI implementation this could for example be an extension of JPanel. The Property editor is responsible for the layout, so the property editor has to know which properties this target has.

See Also:

PropertyEditorTarget#getPropertyEditorClass()

toString

public java.lang.String toString()

getActions

public java.util.Iterator getActions()

Description copied from interface: ActionTarget

Get a bunch of java.util.Action objects that this object wants to offer in a context-menu.

Returns:

an Iterator containing all the actions.

See Also:

ActionTarget#getActions()

actionListCachable

public boolean actionListCachable()

Description copied from interface: ActionTarget

Some objects may alter the list of actions they present depending on the state they are in. If this method returns true, the list of actions can be cached (i.e. the resulting GUI object can be cached and doesn't have to be regenerated all the time)

Returns:

true if the result of getActions() may be cached.

See Also:

ActionTarget#actionListCacheable()

actionListStatic

public boolean actionListStatic()

Description copied from interface: ActionTarget

Some objects may return a list of actions depending on the state they are in or the way they have been created. Others always return the same list of actions without any dependency on the state. If this is the case, this method should return true. Other objects may cache the list of actions and the depending GUI objects on a per-class basis instead of a per-object basis. If this method returns true, actionListCacheable has to return true as well, otherwise it would not make any sense to cache the information here.

getAssociatedDescriptor

public java.lang.Object getAssociatedDescriptor()

Return the descriptor object this node is associated with. E.g. if the node displays a class descriptor, the ClassDescriptor describing the class should be returned. Used for creating a Transferable.

Specified by:

getAssociatedDescriptor in class OjbMetaTreeNode
