Overview

This package contains information about xml schemas, and processes to create parse and interpret Schema. One of the more important function is the simplification of a Schema into the interface in the xsi package, as well as compressing some of the heirarchy.

These classes should be used by assessing the SchemaFactory.

Future Work / Caveat

Work can be completed on two fronts, improving the compression algorithms for the Schema compression. The second major work for this schema should be to encode the Schema parsing (this package) as a Schema Object, using the document parser to complete the same task through an xsi extension.

Although it was evident early on that these tasks were similar, the exact nature and method of bootstrapping the process was not evident. Converting these classes to a Schema definition similar to GML would simplify the code, making it easier to maintain.

This represents an 'all' element in an xml schema.

Represents an 'anyAttribute' element in an xml schema

Represents an 'any' element.

Represents an 'attributeGroup' element.

Represents an 'attribute' element

Example Use:

 AttributeHandler x = new AttributeHandler(...);
 

represtents a 'choice' element

Represents a ComplexType element

When a specific method of encoding is not specified then the following output will be returned: ElementValue[]{(null,Attributes),(Element,Value)*,(null,String)?} Where the last element will be included iff there is child text.

Allows the developer to avoid instanceof operators when wishing to compress.

Represtents an 'element' declaration.

Abstract class representing common Facet abilites + attributes.

Represents a 'field' element.

Representa a 'group' element

Used to represent elements which are not important to our parse, basically place holders.

Represents an 'import' element.

Represents an 'include' element

represents a 'key' element.

represents a 'keyref' element.

represents a 'list' element

represents a 'redefine' element

Represents a restriction element

This is intended to bootstrap the schema parsing

represents a Schema element

Represents a selector element

represents a sequence element

represents a simpleType element

represents a union element

represents a unique element.
