public class Node
implements NodeInterface

Node is a generic implementation of NodeInterface. Node is a single unit in a hierarchical structure. It provides textual descriptions, children and user specified data.

Constructor Detail

Node

public Node()

Constructs a Node object.

Node

public Node(java.lang.String nodeText)

Constructs a Node object with the specified text. The nodeText property will be initialized with the specified text string.

Parameters:

nodeText - the initial value for the nodeText property

Node

public Node(java.lang.String nodeText,
            java.lang.String nodeType)

Constructs a Node object with the specified text and type. The nodeText and nodeType properties will be initialized with the specified text and type strings.

Parameters:

nodeText - the initial value for the nodeText property

nodeType - the initial value for the nodeType property

Method Detail

getNodeExpandedText

public java.lang.String getNodeExpandedText()

Description copied from interface: NodeInterface

Returns the value of the nodeExpandedText property. The expanded text is usually a more descriptive version of the nodeText property. For example, a node that represents a file can return the file name for the nodeText property and the full path name for the nodeExpandedText property.

Specified by:

getNodeExpandedText in interface NodeInterface

Returns:

the nodeExpandedText property

getNodeType

public java.lang.String getNodeType()

Description copied from interface: NodeInterface

Returns the type of the current node. The type is a text string which allows the user of a node hierarchy to add more information to nodes. For example nodes in a file system viewer could use "file" or "directory" as the type to distinguish between nodes representing files and directories.

Specified by:

getNodeType in interface NodeInterface

Returns:

the type of the current node

getNodeText

public java.lang.String getNodeText()

Description copied from interface: NodeInterface

Returns the value of the nodeText property.

Specified by:

getNodeText in interface NodeInterface

Returns:

the nodeText property

isExternalUpdateSupported

public boolean isExternalUpdateSupported()

Returns the value of the externalUpdateSupported property.

Returns:

true to allow external updates, false otherwise

See Also:

setExternalUpdateSupported(boolean)

getNodeTypes

public java.lang.String[] getNodeTypes()

Returns the complete set of types for a node. NOTE: This property is not currently used.

Returns:

null, or a string array of all the possible node types.

addItems

public void addItems(java.util.Enumeration items)

Appends the enumeration of SimpleNodeInterface objects to the children of the current node.

Parameters:

items - the SimpleNodeInterface objects to add as children

getIndex

public int getIndex(javax.swing.tree.MutableTreeNode item,
                    int startIndex)

Returns the 0-based index associated with the NodeInterface object in the children collection (searches forward)

Parameters:

item - NodeInterface to search for

startIndex - the position where the search should start

Returns:

int the 0-based index corresponding to the NodeInterface object or -1 if the item is not found.

Throws:

java.lang.IndexOutOfBoundsException - if the start index is invalid

getObjectData

public java.lang.Object getObjectData()

Returns user-supplied data for the current node.

Returns:

user data for this node

See Also:

setObjectData(java.lang.Object)

setExternalUpdateSupported

public void setExternalUpdateSupported(boolean newValue)

Sets the value of the externalUpdateSupported property.

Parameters:

newValue - true to allow external updates, false otherwise

See Also:

isExternalUpdateSupported()

setNodeExpandedText

public void setNodeExpandedText(java.lang.String newValue)

Sets the expanded text of the current node.

Parameters:

newValue - the new value for the nodeExpandedText property

See Also:

getNodeExpandedText()

setNodeType

public void setNodeType(java.lang.String newValue)

Sets the type of the current node. The type can be used for categorizing nodes.

Parameters:

newValue - the new value for the nodeType property

See Also:

getNodeType()

setNodeText

public void setNodeText(java.lang.String newValue)

Sets the text of the current node.

Parameters:

newValue - the new value for the nodeText property

See Also:

getNodeText()

setObjectData

public void setObjectData(java.lang.Object newValue)

Sets the object data for the current node.

Parameters:

newValue - the new value for the objectData property

See Also:

getObjectData()

toString

public java.lang.String toString()

Returns the value of the nodeText property.

Overrides:

toString in class javax.swing.tree.DefaultMutableTreeNode

Returns:

the value of the nodeText property
