Class SchemaGenerator

  org.eclipse.persistence.jaxb.compiler.SchemaGenerator

public class SchemaGenerator
extends java.lang.Object

INTERNAL:

Purpose:To generate Schema objects based on a map of TypeInfo objects, and some additional information gathered by the AnnotationsProcessing phase.

Responsibilities:

• Create and maintain a collection of Schema objects based on the provided TypeInfo objects
• Add additional global elements to the schema based on an optional map (for WS integration)
• Should create a schema for each namespace encountered during generation.

This class is used by the Generator to handle the generation of Schemas. The Generator passes in a map of TypeInfo objects, generated by the Annotations processor. The generated Schemas are stored in a map of keyed on Target Namespace.

This method will build element/complexType/typedefparticle components for a given xml-path, and return an XmlPathResult instance containg the sequence that the target should be added to, as well as the current schema - which could be different than the working schema used before calling this method in the case of a prefixed path element from a different namespace. Regarding the path 'target', if the xml-path was "contact-info/address/street", "street" would be the target. In this case the sequence containing the "address" element would be set in the XmlPathResult to be returned. The exception case is an 'any', where we want to process the last path element before returning - this is necessary due to the fact that an Any will be added to the sequence in place of the last path element by the calling method.

Parameters:

frag -

xpr -

isAny -

isChoice -

Returns:

elementExistsInParticle

Convenience method for determining if an element already exists in a given typedefparticle. If an element exists whose ref is equal to 'refString' or its name is equal to 'elementName', it is returned. Null otherwise. Note that ref takes precidence, so if either has a ref set name equality will not be performed.

Parameters:

elementName - the non-null element name to look for

refString - if the element is a ref, this will be the prefix qualified element name

particle - the sequence/choice/all to search for an existing element
