Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
**For internal use only** Get a cloned LocPathIterator.

size

public int size()
**For internal use only** Get the length of the list.

addElement

public void addElement(Node value)
**For internal use only** Append a Node onto the vector.

push

public final void push(Node value)
**For internal use only** Append a Node onto the vector.

pop

public final Node pop()

insertElementAt

public void insertElementAt(Node value,
                            int at)
**For internal use only** Inserts the specified node in this vector at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted upward to have an index one greater than the value it had previously.

appendNodes

public void appendNodes(NodeVector nodes)
**For internal use only** Append the nodes to the list.

removeAllElements

public void removeAllElements()
**For internal use only** Inserts the specified node in this vector at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted upward to have an index one greater than the value it had previously.

removeElement

public boolean removeElement(Node s)
**For internal use only** Removes the first occurrence of the argument from this vector. If the object is found in this vector, each component in the vector with an index greater or equal to the object's index is shifted downward to have an index one smaller than the value it had previously.

removeElementAt

public void removeElementAt(int i)
**For internal use only** Deletes the component at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted downward to have an index one smaller than the value it had previously.

setElementAt

public void setElementAt(Node node,
                         int index)
**For internal use only** Sets the component at the specified index of this vector to be the specified object. The previous component at that position is discarded. The index must be a value greater than or equal to 0 and less than the current size of the vector.

elementAt

public Node elementAt(int i)
**For internal use only** Get the nth element.

contains

public boolean contains(Node s)
**For internal use only** Tell if the table contains the given node.

indexOf

public int indexOf(Node elem,
                   int index)
**For internal use only** Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.
Returns:
the index of the first occurrence of the object argument in this vector at position index or later in the vector; returns -1 if the object is not found.

indexOf

public int indexOf(Node elem)
**For internal use only** Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.
Returns:
the index of the first occurrence of the object argument in this vector at position index or later in the vector; returns -1 if the object is not found.
