Class DDParser

java.lang.Object

org.netbeans.modules.schema2beans.DDParser

All Implemented Interfaces:

Iterator

public class DDParser
extends Object
implements Iterator

This class provides an implementation of the Iterator interface. Providing a parsing string (/prop1/prop2/...), the iterator parses the specified BaseBean, searching for the specified properties. As the hasMore()/next() methods are called, the parser goes over all the instances of the BaseBean tree. For example, assuming we have: /Book/Chapters/Title, the iterator would return all the titles of all the Chapters of the book. The iterator always returns elements of the type specified as the last element of the parsing string. In the above example, the parser would return only Title elements. If the parsing string is /EnterpriseBean/Entity, the parser would return all the Entity beans of the tree. Therefore, the type returned can be either a BaseBean or a final property type. Note that in case of a final property value, only objects are returned. Scalar types are wrapped using the appropriate class (int/Integer, ...). TODO: support for attributes, keys and limited arrays (only first element for example).

Constructor Detail

DDParser

public DDParser(BaseBean root,
                String parse)

Build the PropParser from the parsing String. The PropParser class does all the work.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator

next

public Object next()

Specified by:

next in interface Iterator

current

public Object current()

remove

public void remove()

Specified by:

remove in interface Iterator

getLocation

public DDParser.DDLocation getLocation()

Return the current position of the parser. The position is made of a baseBean (parent of the property), the property name, and its index value, if this is an indexed property.
