Class xe.xe_ParseManager
java.lang.Object
|
+----xe.xe_Tokenizer
|
+----xe.xe_ParseManager
- public class xe_ParseManager
- extends xe_Tokenizer
Perform low-level parsing of an XML source and keep the state of the
current parse (by inheriting from xe_Tokenizer). Also provide access to the
factory for creating parsers and manages the parse listener (if there is
one).
The parsing of the different parts of an XML source are created by an
xe_ParserFactory held herein. Specialised parsers can be added by registering
with xe_TokenType the keywords to which they relate.
-
xe_ParseManager()
- Default constructor.
-
certifyNewNode(xg_Node, xg_Node)
- Add InputNewNode to its parent (hence the name of this method: we're issuing
its birth certificate), and then tell the outside world about this joyous
event.
-
createEntity(String, int, String, String, xg_Node)
-
Create an entity of the type suitable for the entity whose type is
'InputEntityName'.
-
createParser(String, int)
- Create a parser suitable for parser the entity whose name is giving in
InputEntityName.
-
fireEndNodeEvent(xg_Node)
- Send an 'end node' event to the parse listener.
-
fireStartNodeEvent(xg_Node, int)
- Send a 'start node' event to the parse listener.
-
setParseListener(xm_ParseListener)
- Set the parse listener which is to be informed of parse events.
xe_ParseManager
public xe_ParseManager()
- Default constructor.
createParser
public xe_Parser createParser(String InputNodeName,
int InputNodeType) throws xm_ParseException
- Create a parser suitable for parser the entity whose name is giving in
InputEntityName.
- Parameters:
- InputNodeName - The name of the node for which we need a parser
- InputNodeType - The type of node for which we need a parser
- Returns:
- The newly-created parser for the named entity
- Throws: xm_ParseException
- Either no parser class is registered
or it cannot be instantiated
createEntity
public xg_Node createEntity(String InputEntityName,
int InputNodeType,
String InputNodePrecedingWhitespace,
String InputUsualClassName,
xg_Node InputParentNode) throws xm_ParseException
-
Create an entity of the type suitable for the entity whose type is
'InputEntityName'. The entity created is guaranteed to be an instance of
the class whose name is InputUsualClassName - or a derived class.
Non-standard entities can be added by registering with xe_NodeTypeRegistry
the names to which they relate.
- Parameters:
- InputEntityName - The name of the node we to create
- InputNodeType - The type of node we need to create
- InputNodePrecedingWhitespace - The whitespace which precedes the new
node
- InputUsualClassName - The name of the class which is usually used to
represent entities of this type. The class
actually used must be this or a derived from it.
- InputParentNode - The parent of the new entity. The newly-created
entity is added as a child of this parent.
- Returns:
- The newly-created entity
- Throws: xm_ParseException
- XML wellformedness error
certifyNewNode
public void certifyNewNode(xg_Node InputNewNode,
xg_Node InputParentNode) throws xm_ParseException
- Add InputNewNode to its parent (hence the name of this method: we're issuing
its birth certificate), and then tell the outside world about this joyous
event.
- Parameters:
- InputNewNode - The new node being certified.
- InputParentNode - The parent of the new node. The newly-created
node is added as a child of this parent.
- Throws: xm_ParseException
- XML wellformedness error
setParseListener
public void setParseListener(xm_ParseListener InputParseListener)
- Set the parse listener which is to be informed of parse events.
fireStartNodeEvent
public void fireStartNodeEvent(xg_Node InputNewNode,
int InputStartPosition)
- Send a 'start node' event to the parse listener.
- Parameters:
- InputNewNode - The node whose start has just been parsed
- InputStartPosition - The offset from the start of the source at
which this node starts
fireEndNodeEvent
public void fireEndNodeEvent(xg_Node InputNewNode) throws xm_ParseException
- Send an 'end node' event to the parse listener.
- Parameters:
- InputNewNode - The node which has just been parsed
