Overrides:

addItems in class OrderedCollection

Parameters:

items - an Enumeration of items to add to this collection

index - insert the objects starting before the indexed item. The first of the newly inserted item can be accessed by get(index) afterwards.

Return the Font corresponding to the name provided.

Parameters:

fontName - a String corresponding to the font

Returns:

Font The com.sas.awt.Font associated with fontName.

getFonts

public java.util.Enumeration getFonts()

Returns an enumeration of java.awt.Font objects.

getNodeExpandedText

public java.lang.String getNodeExpandedText()

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

getNodeText

public java.lang.String getNodeText()

Returns the value of the nodeText property.

Specified by:

getNodeText in interface NodeInterface

Returns:

the nodeText property

getNodeType

public java.lang.String getNodeType()

Returns the value of the nodeType property. The type can be used for categorizing nodes.

Specified by:

getNodeType in interface NodeInterface

Returns:

the nodeType property

countNodeChildren

public int countNodeChildren(int maximumChildCount)

Counts the children of the current node. countNodeChildren differs from getNodeChildCount when the number of children is not readily known. In such a case, getNodeChildCount will simply return -1 to indicate that the count is unknown, while countNodeChildren will actually compute the answer; thus countNodeChildren is a potentially expensive operation. To limit this potential overhead, a maximum child count may be passed to this method, such that the implementation will not read more than that many children. If exactly the number of children specified as the maximum count to read exists under the current node then a value equal in magnitude but opposite in sign (-maximumChildCount) should be returned.

Specified by:

countNodeChildren in interface SimpleNodeInterface

Parameters:

maximumChildCount - the maximum number of children to read, or 0 to read indefinitely

Returns:

The number of children known to be available.

getNodeChildCount

public int getNodeChildCount()

Returns the number of children available. If the number of children is unknown, -1 should be returned.

Specified by:

getNodeChildCount in interface SimpleNodeInterface

Returns:

the number of children or -1 if unknown

isLeafNode

public boolean isLeafNode()

Indicates whether the current node is a leaf. A true value indicates that the current node is a leaf and hence will not have any children.

Specified by:

isLeafNode in interface SimpleNodeInterface

Returns:

true if the current node is a leaf, otherwise false

getNodeChild

public SimpleNodeInterface getNodeChild(int index)

Returns the child node at the specified index.

Specified by:

getNodeChild in interface SimpleNodeInterface

Parameters:

index - the 0-based index of the child node to retrieve

Returns:

the child at index or null if the leafNode property value is true.

getNodeChildren

public SimpleNodeInterface[] getNodeChildren(int startIndex,
                                             int count)

Returns the specified range of children for the current node. If there are less children than are queried for, an implementation can return an array whose size if representative of the actual number of children being returned or an array whose size is the same as the number of children asked for. If the resulting array's size is the same as the number asked for and there are fewer children returned than asked for the implementation should assign the unused values in the array to null.

Specified by:

getNodeChildren in interface SimpleNodeInterface

Parameters:

startIndex - 0-based index which identifies the start of the range

count - the amount of children to get

Returns:

an array containing the specified range of children or null if the leafNode property value is true.
