Constructor Detail

TarBranchDataNode

public TarBranchDataNode(TarStreamDataNode tarnode,
                         org.apache.tools.tar.TarEntry entry)
Constructs a TarBranchDataNode from a TarEntry and TarStreamArchive.

Parameters:
tarnode - DataNode representing the tar file within which this entry lives
entry - the TarEntry object represented by this node
Method Detail

getName

public String getName()
Description copied from interface: DataNode
Gets the name of this object. This is an intrinsic property of the object.

Specified by:
getName in interface DataNode
Overrides:
getName in class DefaultDataNode
Returns:
the name of the object

getPathElement

public String getPathElement()
Description copied from class: DefaultDataNode
The DefaultDataNode implementation returns the label as a default path element.

Specified by:
getPathElement in interface DataNode
Overrides:
getPathElement in class DefaultDataNode
Returns:
the node's label

getPathSeparator

public String getPathSeparator()
Description copied from class: DefaultDataNode
Returns a default separator string.

Specified by:
getPathSeparator in interface DataNode
Overrides:
getPathSeparator in class DefaultDataNode
Returns:
"."

getNodeTLA

public String getNodeTLA()
Description copied from class: DefaultDataNode
The DefaultDataNode implementation returns the string "...".

Specified by:
getNodeTLA in interface DataNode
Overrides:
getNodeTLA in class DefaultDataNode
Returns:
"..."

getNodeType

public String getNodeType()
Description copied from interface: DataNode
Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.

Specified by:
getNodeType in interface DataNode
Overrides:
getNodeType in class DefaultDataNode
Returns:
a short description of the type of this DataNode

allowsChildren

public boolean allowsChildren()
Description copied from class: DefaultDataNode
The DefaultDataNode implementation of this method returns false.

Specified by:
allowsChildren in interface DataNode
Overrides:
allowsChildren in class DefaultDataNode
Returns:
true if the node is of a type which can have child nodes, false otherwise

getChildIterator

public Iterator getChildIterator()
Description copied from class: DefaultDataNode
The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).

Specified by:
getChildIterator in interface DataNode
Overrides:
getChildIterator in class DefaultDataNode
Returns:
an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.

configureDetail

public void configureDetail(DetailViewer dv)
Description copied from class: DefaultDataNode
No custom configuration is performed.

Specified by:
configureDetail in interface DataNode
Overrides:
configureDetail in class DefaultDataNode
Parameters:
dv - the detail viewer which this node is given an opportunity to configure
