Method Details

• getSchemaValidationContext

  public ValidationContext getSchemaValidationContext()

  Get the validation context used for processing schemas.

  Returns:

  context

• addDefaultSubstitutions

  private static void addDefaultSubstitutions(SchemasetCustom custom)

  Add default type substitutions to set currently defined.

  Parameters:

  custom -

• findSchemaset

  public SchemasetCustom findSchemaset(SchemaElement schema, SchemasetCustom custom)

  Find the most specific schemaset owning a schema. If multiple matches are found which are not in line of containment the first match is returned and the conflict is reported as an error.

  Parameters:

  schema -

  custom - schema set customization

  Returns:

  owning schemaset, null if none

• setDefaultPrefixes

  public void setDefaultPrefixes(Iterator iter)

  Scan schemas to find the default prefixes used for namespaces.

  Parameters:

  iter - schema iterator

• customizeSchemas

  public boolean customizeSchemas(String pack, ProblemHandler handler)

  Validate and apply customizations to loaded schemas.

  Parameters:

  pack - package to be used by default for no-namespaced schemas (non-null)

  handler - validation problem handler

  Returns:

  true if successful, false if error

• processExtensions

  private boolean processExtensions()

  Process substitutions and deletions defined by extensions. This builds the cross-reference information for the global definition components of the schemas while removing references to deleted components.

  Returns:

  true if any changes to the schemas, false if not

• applyAndNormalize

  public void applyAndNormalize()

  Apply extensions and normalize all schemas. This may be a multipass process, since applying extensions may create the opportunity for further normalizations and vice versa.

• pruneDefinitions

  public void pruneDefinitions()

  Processes the schemas to remove unused global definitions.

• checkDirectName

  private String checkDirectName(Item item)

  Check if an item has an associated name. If the component associated with the item has a name, this just returns that name converted to base name form. The only exception is for inlined global type definitions, which are treated as unnamed.

  Parameters:

  item -

  Returns:

  name associated name, or null if none

• deriveName

  private String deriveName(Item item, boolean force)

  Derive the base name for an item. If not forced, the only time a name will be returned is when the item is a reference to a non-type definition. If forced, this will try other alternatives for names including the text "Enumeration" for an enumeration group, the base type name for a type derivation, the schema type name for a value of a schema type, or finally the schema component element name.

  Parameters:

  item -

  force - name forced flag

  Returns:

  name (null if to use inherited name when force == false)

• compactGroups

  private void compactGroups(GroupItem group)

  Compact group structures. This eliminates redundant groupings, in the form of groups with only one child, which child is a group referencing the same schema component as the parent group, from the data structure representation.

  Parameters:

  group -

• assembleName

  private String assembleName(String prefix, String base)

  Assemble a name from a base name and an optional prefix. If the prefix is supplied, this first converts the base name to embedded form, then appends the prefix.

  Parameters:

  prefix -

  base -

  Returns:

  name

• assignNames

  private void assignNames(String prefix, GroupItem group, boolean force)

  Set the basic names to be used for a structure of items. For named components of the schema definition the names used are simply the converted XML local names, for other components more complex rules apply (see deriveName(Item,boolean). This method calls itself recursively to handle nested groups.

  Parameters:

  prefix - text to be prefixed to names within inlined group (null if none)

  group - item group to be assigned

  force - force name derivation flag

• computeComplexity

  private int computeComplexity(GroupItem group, int depth, List defs)

  Compute the complexity of a structure. In order to find the complexity of a structure all items of the structure must first be checked for inlining, which in turn requires checking their complexity. That makes this method mutually recursive with checkInline(DefinitionItem, int, List).

  Parameters:

  group -

  depth - nesting depth

  defs - list of generated definitions

  Returns:

  complexity (0, 1, or 2 for anything more than a single value)

• isSimple

  private boolean isSimple(GroupItem group)

  Check if a group consists only of a single non-repeating item, which is not an enumeration.

  Parameters:

  group -

  Returns:

  true if simple group, false if repeated, multiple, or enumeration

• convertToDefinitions

  private void convertToDefinitions(GroupItem group, List defs)

  Convert nested groups which are not inlined to freestanding definitions. This calls itself recursively to process nested groups, except those nested within groups converted to definitions.

  Parameters:

  group -

  defs - list of generated definitions

• checkInline

  private void checkInline(DefinitionItem def, int depth, List defs)

  Check if a global definition structure is to be inlined. This method is mutually recursive with computeComplexity(GroupItem, int, List). The two methods together determine the inlining status of all items.

  Parameters:

  def -

  depth - nesting depth

  defs - list of generated definitions

• setName

  private void setName(QName qname, MappingElementBase mapping, BindingHolder holder)

  Set the name and namespace URI for a concrete <mapping> binding component. This is the same logic as used in the StructureClassHolder equivalent.

  Parameters:

  qname - qualified name to be set (null if none)

  mapping - concrete mapping definition

  holder - binding containing the mapping

• buildItemStructures

  private ArrayList buildItemStructures()

  Build the structure of items to be used in code generation for each global definition.

  Returns:

  constructed definition items

• convertTypeIsomorphicElements

  private Map convertTypeIsomorphicElements(ArrayList items)

  Convert the item model used for global elements, if they're the only reference to a global type. This just prevents generating two separate classes, one for the type and one for the element.

  Parameters:

  items - global definition items

  Returns:

  map from base type definition to singleton element definition using that type

• inlineReferences

  private ArrayList inlineReferences(ArrayList items)

  Build list of definitions to be generated. Where possible, references are converted to inline definitions. Where they can't be converted, new definitions are created for separate class generation.

  Parameters:

  items -

  Returns:

  definitions to be processed

• checkNoNamespacedUsed

  private boolean checkNoNamespacedUsed()

  Check if no-namespace namespace is used in any of the schemas.

  Returns:

  true if no-namespace used, false if not

• buildClassesAndBindings

  private void buildClassesAndBindings(ArrayList defs, Map typeinst)

  Build classes and bindings for all definitions, except those for singleton element definitions using a type.

  Parameters:

  defs - definitions to be generated

  typeinst - map from base type definition to singleton element definition using that type

• initializeBindings

  private void initializeBindings()

  Initialize the bindings to be generated. This configures the binding directory, then creates the required bindings and sets their prefixes.

• buildDataModel

  public String buildDataModel(boolean verbose, boolean usenns, Map elemmap, Map typemap)

  Generate the data model. This first builds a representation of all the data items from the schema definitions, then determines which items can be inlined and which need separate class representations, and finally builds the actual data model class and binding definitions.

  Parameters:

  verbose - verbose output flag

  usenns - no-namespace namespace used flag

  elemmap - map from qualified name of element to pregenerated mapping definition

  typemap - map from qualified name of type (or attributeGroup, or group) to pregenerated mapping definition

  Returns:

  root package for binding

• getBindingDirectory

  public BindingOrganizer getBindingDirectory()

  Get the binding directory.

  Returns:

  directory

• writeBindings

  public void writeBindings(String name, String pack, List pregens, ProblemHandler handler) throws JiBXException, IOException
