Class XMLFragmentStreamReaderImpl

java.lang.Object
  org.apache.tuscany.sca.databinding.xml.XMLFragmentStreamReaderImpl

All Implemented Interfaces:: javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader, XMLFragmentStreamReader

public class XMLFragmentStreamReaderImpl
extends java.lang.Object
implements XMLFragmentStreamReader
extends java.lang.Object
implements XMLFragmentStreamReader

This is the new implementation of the XMLFramentStreamReader. The approach here is simple When the pull parser needs to generate events for a particular name-value(s) pair it always hands over (delegates) the task to another pull parser which knows how to deal with it The common types of name value pairs we'll come across are

String name/QName name - String value
String name/QName name - String[] value
QName name/String name - XMLStreamReader value
QName name/String name - XMLStreamable value
QName name/String name - Java bean
QName name/String name - Datahandler

As for the attributes, these are the possible combinations in the array

String name/QName name - String value

Note that certain array methods have been deliberately removed to avoid complications. The generated code will take the trouble to lay the elements of the array in the correct order

Hence there will be a parser impl that knows how to handle these types, and this parent parser will always delegate these tasks to the child pullparasers in effect this is one huge state machine that has only a few states and delegates things down to the child parsers whenever possible

`javax.xml.stream.Location`	`getLocation()`
`javax.xml.namespace.QName`	`getName()`
`javax.xml.namespace.NamespaceContext`	`getNamespaceContext()`

`java.lang.String`	`getText()`
`char[]`	`getTextCharacters()`
`int`	`getTextCharacters(int i, char[] chars, int i1, int i2)`
`int`	`getTextLength()`
`int`	`getTextStart()`
`java.lang.String`	`getVersion()`
`boolean`	`hasName()`
`boolean`	`hasNext()`
`boolean`	`hasText()` check the validity of this implementation
`void`	`init()` we need to split out the calling to the populate namespaces separately since this needs to be done after setting the parent namespace context.
`boolean`	`isAttributeSpecified(int i)`
`boolean`	`isCharacters()`
`boolean`	`isDone()` are we done ?
`boolean`	`isEndElement()`
`boolean`	`isStandalone()`
`boolean`	`isStartElement()`
`boolean`	`isWhiteSpace()`
`int`	`next()` By far this should be the most important method in this class this method changes the state of the parser
`int`	`nextTag()` TODO implement this
`void`	`require(int i, java.lang.String string, java.lang.String string1)`
`void`	`setParentNamespaceContext(javax.xml.namespace.NamespaceContext nsContext)` add the namespace context
`boolean`	`standaloneSet()`
