Constructor Summary

Node()
Construct an empty node.

Node(int nodeType, java.awt.Point location)
Construct and initialize a node.

Method Summary

int	getDialogsCount() Get dialog count
static int	getQueryCount() Get methods for the counters (e.g., getQueryCount for queries).
java.lang.String	getRoot() Return the name of the root of the DTD.
void	incrementDialogsCount() Increment dialog count, i.e.
ParsedData	isParsed(java.lang.String string) Returns the reference of the ParsedData if it occurs more than once in the DTD, so that we dont have infinite looping.
void	loadNode(java.io.ObjectInputStream in) Load this node's state.
void	loadNodeParsedData(java.io.ObjectInputStream in, ParsedData pd) Load this node's Parsed Data state.
void	makeLinks(ParsedData pd) Method to make links for parent element to know its sub elements, if this element has already been parsed before and if it has subelements
ParsedData	recursiveIsParsed(ParsedData pd, java.lang.String string) This is doing the recursive job of traversing through the data structures and returns the answer needed by isParsed
static void	reset() Reset the counters.
void	saveNode(java.io.ObjectOutputStream out) Save this node's state.
void	saveNodeParsedData(java.io.ObjectOutputStream out, ParsedData pd) Save this node's Parsed Data state.
void	setDialogsCount(int c) Set dialog count
static void	setQueryCount(int c) Set methods for the counters (e.g., setQueryCount for queries).
void	unpack() Unpack the node: polyg and color are derivable from nodeType and location.

Constructor Detail

Node

public Node()

Construct an empty node.

Node

public Node(int nodeType,
            java.awt.Point location)

Construct and initialize a node.

Parameters:

nodeType - type of node

location - location (top left) of node

Method Detail

reset

public static void reset()

Reset the counters.

getRoot

public java.lang.String getRoot()

Return the name of the root of the DTD.

setQueryCount

public static void setQueryCount(int c)

Set methods for the counters (e.g., setQueryCount for queries).

getQueryCount

public static int getQueryCount()

Get methods for the counters (e.g., getQueryCount for queries).

unpack

public void unpack()

Unpack the node: polyg and color are derivable from nodeType and location.

saveNode

public void saveNode(java.io.ObjectOutputStream out)
              throws java.io.IOException

Save this node's state.

Parameters:

Get dialog count

setDialogsCount

public void setDialogsCount(int c)

Set dialog count

loadNode

makeLinks

public void makeLinks(ParsedData pd)

Method to make links for parent element to know its sub elements, if this element has already been parsed before and if it has subelements

Parameters:

pd - ParsedData under consideration

isParsed

public ParsedData isParsed(java.lang.String string)

Returns the reference of the ParsedData if it occurs more than once in the DTD, so that we dont have infinite looping. This reference is then cloned and used as needed at runtime

Parameters:

string - name of element as in the DTD

Returns:

ParsedData The ParsedData reference which is the child of the element string, if there is one, else null

string - element name

Returns:

ParsedData The ParsedData reference which is the child of the element string, if there is one, else null
