Package oracle.jdeveloper.xml.schema.dependency Description

Provides dependency information for XML Schema.

This package provides declaration classes for XML Schema elements, attributes, attribute groups, model groups, complex types, and simple types. Corresponding reference classes are also provided. These classes are used to provide information about dependencies between XML schemas.

In addition, these declaration and reference classes can be used by other languages that use XML Schema datatypes (for example, WSDL, XSLT, and XQuery). If the language is an XML language, the language provider simply needs to add XDF metadata for their language which maps the attributes in that language to the corresponding reference factory classes in this package. For example, if the language defines a "type" attribute which points to an XML Schema type, the XDF metadata would be as follows:

   <attributeMetadata attributeName="type">
     <mmd:reference>oracle.jdeveloper.xml.schema.dependency.TypeReferenceFactory</mmd:reference>
   </attributeMetadata>
 

If the language uses XML Schema import elements to import schemas, then no further steps should be required. If the language defines its own elements for importing schemas, the language provider must provide XDF references for those elements. These elements should be mapped to SchemaReferenceFactory or a subclass created by the language provider. The language provider can override the getSchemaLocation method to return the URL of the imported schema. This will enable the XML Schema reference classes to locate declarations defined in those schemas. For example, if the langauge defines an import element with a "location" attribute containing the URL of the imported schema, the XDF metadata would be:

   <elementMetadata elementName="import">
     <attributeMetadata attributeName="location">
       <mmd:reference>oracle.jdeveloper.xml.schema.dependency.SchemaReferenceFactory</mmd:reference>
     </attributeMetadata>
   </elementMetadata>
 

For non-XML languages, such as XQuery, the language provider will need to provide its own XDF references which point the XML Schema declarations. See the XDF documentation.
