Enum Constant Summary

Enum Constants

Enum Constant and Description
ALWAYS Specifies that a tree should not show the collapse/expand icon for the node, because this node cannot have any children.
ASYNC Specifies that a tree should show the collapse/expand icon for the node, only if this node have some children.
DEFAULT Specifies that a tree should show the collapse/expand icon for the node, only if this node have some children.
NEVER Specifies that a tree should always show the collapse/expand icon for the node, even if this node have no children.

Method Summary

Modifier and Type	Method and Description
static LeafState	get(java.lang.Object node)
static LeafState	get(java.lang.Object node, javax.swing.tree.TreeModel model)
static LeafState	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static LeafState[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

ALWAYS

public static final LeafState ALWAYS

Specifies that a tree should not show the collapse/expand icon for the node, because this node cannot have any children.

See Also:

AbstractTreeNode.isAlwaysLeaf()

NEVER

public static final LeafState NEVER

Specifies that a tree should always show the collapse/expand icon for the node, even if this node have no children.

See Also:

AbstractTreeNode.isAlwaysShowPlus()

DEFAULT

public static final LeafState DEFAULT

Specifies that a tree should show the collapse/expand icon for the node, only if this node have some children. By default, children are counted immediately that may cause performance problems.

See Also:

TreeModel.getChildCount(Object)

ASYNC

public static final LeafState ASYNC

Specifies that a tree should show the collapse/expand icon for the node, only if this node have some children. In this mode children are counted later that may cause a "blinking" of the collapse/expand icon.

Method Detail

values

public static LeafState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LeafState c : LeafState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LeafState valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

get

public static LeafState get(java.lang.Object node)

Parameters:

node - a tree node, which leaf state interested in

Returns:

a leaf state of the specified tree node, or DEFAULT value

get

public static LeafState get(java.lang.Object node,
                            javax.swing.tree.TreeModel model)

Parameters:

node - a tree node, which leaf state interested in

model - a tree model used to resolve a leaf state of the specified tree node

Returns:

a resolved leaf state of the specified tree node according to the given model
