Method Detail

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

childFinished

public void childFinished(ItemParser child)

Description copied from class: ItemParser

this method will be called, as soon as the a child ItemParser finished and returned from its end() method. This implementation does nothing. Subclasses should nevertheless make a super call.

Overrides:

childFinished in class ItemParser

Parameters:

child - the child ItemParser, which just finished

handleLabels

protected void handleLabels()

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

getItem

public 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
