Class SchemaTypeLinking

java.lang.Object
  dk.brics.xact.analysis.transformations.SchemaTypeLinking

public class SchemaTypeLinking
extends Object

Loads all XML schemas used by the program and then builds an XML graph containing:

• All types defined in loaded XML schemas.
• The necessary types from the XMLSchema-datatypes namespace.
• The necessary quantified versions of those types (suffixed ?,+, or * accordingly)

Additionally, only ChoiceNodes can have element and attribute nodes as content, and the contents of each element node will be a ChoiceNode.

A quantified type is the name of a type suffixed with ?, + or *, corresponding to the zero-or-one, one-or-more and zero-or-more operators. Quantifiers can appear both inside and outside of gap annotations. For example, these are all types that use quantifiers:

  foo+
  foo[bar* X]
  foo*[bar+ Z]
  foo[bar? X, baz? Y]
