Field Detail

m_firstFree

protected int m_firstFree

Number of nodes in this NodeVector.

Constructor Detail

NodeVector

public NodeVector()

Default constructor.

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

size

public int size()

Get the length of the list.

Returns:

Number of nodes in this NodeVector

addElement

public void addElement(int value)

Append a Node onto the vector.

Parameters:

value - Node to add to the vector

peepOrNull

public final int peepOrNull()

Return the node at the top of the stack without popping the stack. Special purpose method for TransformerImpl, pushElemTemplateElement. Performance critical.

Returns:

Node at the top of the stack or null if stack is empty.

insertElementAt

public void insertElementAt(int value,
                            int at)

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.

Parameters:

value - Node to insert

at - Position where to insert

RemoveAllNoClear

public void RemoveAllNoClear()

Set the length to zero, but don't clear the array.

elementAt

public int elementAt(int i)

Get the nth element.

Parameters:

i - Index of node to get

Returns:

Node at specified index

contains

public boolean contains(int s)

Tell if the table contains the given node.

Parameters:

s - Node to look for

Returns:

True if the given node was found.

indexOf

public int indexOf(int elem,
                   int index)

Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.

Parameters:

elem - Node to look for

index - Index of where to start the search

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(int elem)

Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.

Parameters:

elem - Node to look for

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.
