Class NodeGraphicsParser

java.lang.Object
  y.io.gml.ItemParser
      y.io.gml.NodeGraphicsParser

All Implemented Interfaces:

GMLTokenizer.Callback

public class NodeGraphicsParser
extends ItemParser

This class will parse the node graphics section from a valid GML file and create appropriate NodeRealizers

Constructor Summary

NodeGraphicsParser(java.net.URL contextURL)

Method Summary

void	begin() this method will be called as soon as the parser enters the scope.
void	beginScope(java.lang.String scopeName) Note: subclass implementers should make a super call, if they want to overwrite this method.
protected java.lang.String	decodeType(java.lang.String externalName) Returns the qualified class name for the given external name.
void	end() this method will be called as soon as the parser leaves the scope.
java.lang.Object	getItem() Returns the "product" of this scope.
NodeRealizer	getNodeRealizer() Gets the node realizer that is the result of this parsing process.
static byte	getShape(java.lang.String name) Decodes a ShapeNodeRealizer.getShapeType() given a String representation.
protected java.net.URL	getURL(java.lang.String resource, java.net.URL contextURL) Tries to resolve an resource as an URL using a given context URL.

Method Detail

beginScope

public void beginScope(java.lang.String scopeName)

Description copied from class: ItemParser

Note: subclass implementers should make a super call, if they want to overwrite this method.

Specified by:

beginScope in interface GMLTokenizer.Callback

Overrides:

beginScope in class ItemParser

Parameters:

scopeName - the name of the scope

begin

public void begin()

Description copied from class: ItemParser

this method will be called as soon as the parser enters the scope. This implementation will clear the attribute map. Subclasses should therefore make a super call.

Overrides:

begin in class ItemParser

end

public void end()

Description copied from class: ItemParser

this method will be called as soon as the parser leaves the scope. This implementation does nothing. Subclasses should nevertheless make a super call.

Overrides:

end in class ItemParser

decodeType

protected java.lang.String decodeType(java.lang.String externalName)

Returns the qualified class name for the given external name.

By default, this method delegates to YGFIOHandler.decode(String).

Note: To prevent obfuscation from breaking user data and style property serialization, an explicit class name encoding should be specified for user data types and style property value types.

See Also:

YGFIOHandler.addEncoding(String, String), NodeRealizerObjectEncoder.encodeType(String)

getURL

protected java.net.URL getURL(java.lang.String resource,
                              java.net.URL contextURL)

Tries to resolve an resource as an URL using a given context URL.

getNodeRealizer

public NodeRealizer getNodeRealizer()

Gets the node realizer that is the result of this parsing process.

getItem

public java.lang.Object getItem()

Description copied from class: ItemParser

Returns the "product" of this scope. This method should be called after this parser has left the scope, i.e. after ItemParser.end() has been called. The latter should construct the resulting item from the collected data and this item should be returned by this method. By default, this method return the map of the attributes.

Overrides:

getItem in class ItemParser

Returns:

the result of the parsing, in this case a Map

getShape

public static byte getShape(java.lang.String name)

Decodes a ShapeNodeRealizer.getShapeType() given a String representation.
