Method Detail

setElementName

public static void setElementName(org.apache.ws.commons.schema.XmlSchemaElement element,
                                  String name)

Wrapper around XmlSchemaElement.setName that checks for inconsistency with refName.

Parameters:

                                     QName name)

Wrapper around XmlSchemaElement.setRefName that checks for inconsistency with name and QName.

Parameters:

element -

name -

isEumeration

public static boolean isEumeration(org.apache.ws.commons.schema.XmlSchemaSimpleType type)

Return true if a simple type is a straightforward XML Schema representation of an enumeration. If we discover schemas that are 'enum-like' with more complex structures, we might make this deal with them.

Parameters:

type - Simple type, possible an enumeration.

Returns:

true for an enumeration.

enumeratorValues

public static List<String> enumeratorValues(org.apache.ws.commons.schema.XmlSchemaSimpleType type)

Retrieve the string values for an enumeration.

Parameters:

type -

Returns:

schemaImportsNamespace

public static boolean schemaImportsNamespace(org.apache.ws.commons.schema.XmlSchema schema,
                                             String namespaceUri)

Is there an import for a particular namespace in a schema?

Parameters:

schema -

namespaceUri -

Returns:

addImportIfNeeded

public static void addImportIfNeeded(org.apache.ws.commons.schema.XmlSchema schema,
                                     String namespaceUri)

Assist in managing the required for imports of peer schemas.

Parameters:

schema -

namespaceUri -

addImportIfNeeded

public static void addImportIfNeeded(org.apache.ws.commons.schema.XmlSchema schema,
                                     QName qname)

For convenience, start from a qname, and add the import if it is non-null and has a namespace.

Parameters:

schema -

qname -

addImportIfNeeded(XmlSchema, String)

findElementByRefName

public static org.apache.ws.commons.schema.XmlSchemaElement findElementByRefName(SchemaCollection xmlSchemaCollection,
                                                                                 QName name,
                                                                                 String referencingURI)

This copes with an observed phenomenon in the schema built by the ReflectionServiceFactoryBean. It is creating element such that: (a) the type is not set. (b) the refName is set. (c) the namespaceURI in the refName is set empty. This apparently indicates 'same Schema' to everyone else, so thus function implements that convention here. It is unclear if that is a correct structure, and it if changes, we can simplify or eliminate this function.

Parameters:

name -

referencingURI -

Returns:

getBaseType

public static QName getBaseType(org.apache.ws.commons.schema.XmlSchemaComplexType type)

getContentAttributes

public static List<org.apache.ws.commons.schema.XmlSchemaAttributeOrGroupRef> getContentAttributes(org.apache.ws.commons.schema.XmlSchemaComplexType type)

getContentAttributes

public static List<org.apache.ws.commons.schema.XmlSchemaAnnotated> getContentAttributes(org.apache.ws.commons.schema.XmlSchemaComplexType type,
                                                                                         SchemaCollection collection)

getContentElements

public static List<org.apache.ws.commons.schema.XmlSchemaObject> getContentElements(org.apache.ws.commons.schema.XmlSchemaComplexType type,
                                                                                    SchemaCollection collection)

getContentSequence

public static org.apache.ws.commons.schema.XmlSchemaSequence getContentSequence(org.apache.ws.commons.schema.XmlSchemaComplexType type)

getElementQualifiedName

public static QName getElementQualifiedName(org.apache.ws.commons.schema.XmlSchemaElement element,
                                            org.apache.ws.commons.schema.XmlSchema schema)

By convention, an element that is named in its schema's TNS can have a 'name' but no QName. This can get inconvenient for consumers who want to think about qualified names. Unfortunately, XmlSchema elements, unlike types, don't store a reference to their containing schema.

Parameters:

element -

schema -

Returns:

getElementType

public static org.apache.ws.commons.schema.XmlSchemaType getElementType(SchemaCollection xmlSchemaCollection,
                                                                        String referencingURI,
                                                                        org.apache.ws.commons.schema.XmlSchemaElement element,
                                                                        org.apache.ws.commons.schema.XmlSchemaType containingType)

Follow a chain of references from element to element until we can obtain a type.

Parameters:

element -

Returns:

getObjectAnnotated

public static org.apache.ws.commons.schema.XmlSchemaAnnotated getObjectAnnotated(org.apache.ws.commons.schema.XmlSchemaObject object,
                                                                                 QName contextName)

If the object is an attribute or an anyAttribute, return the 'Annotated'. If it's not one of those, or it's a group, throw. We're not ready for groups yet.

Parameters:

object -

Returns:

getObjectParticle

public static org.apache.ws.commons.schema.XmlSchemaParticle getObjectParticle(org.apache.ws.commons.schema.XmlSchemaObject object,
                                                                               QName contextName)

If the object is an element or an any, return the particle. If it's not a particle, or it's a group, throw. We're not ready for groups yet.

Parameters:

object -

Returns:

getReferredElement

public static org.apache.ws.commons.schema.XmlSchemaElement getReferredElement(org.apache.ws.commons.schema.XmlSchemaElement element,
                                                                               SchemaCollection xmlSchemaCollection)

getSequence

public static org.apache.ws.commons.schema.XmlSchemaSequence getSequence(org.apache.ws.commons.schema.XmlSchemaComplexType type)

getChoice

public static org.apache.ws.commons.schema.XmlSchemaChoice getChoice(org.apache.ws.commons.schema.XmlSchemaComplexType type)

getAll

public static org.apache.ws.commons.schema.XmlSchemaAll getAll(org.apache.ws.commons.schema.XmlSchemaComplexType type)

isAttributeNameQualified

public static boolean isAttributeNameQualified(org.apache.ws.commons.schema.XmlSchemaAttribute attribute,
                                               org.apache.ws.commons.schema.XmlSchema schema)

isAttributeQualified

public static boolean isAttributeQualified(org.apache.ws.commons.schema.XmlSchemaAttribute attribute,
                                           boolean global,
                                           org.apache.ws.commons.schema.XmlSchema localSchema,
                                           org.apache.ws.commons.schema.XmlSchema attributeSchema)

due to a bug, feature, or just plain oddity of JAXB, it isn't good enough to just check the form of an element and of its schema. If schema 'a' (default unqualified) has a complex type with an element with a ref= to schema (b) (default unqualified), JAXB seems to expect to see a qualifier, anyway.
So, if the element is local to a complex type, all we care about is the default element form of the schema and the local form of the element.
If, on the other hand, the element is global, we might need to compare namespaces.

Parameters:

attribute - the attribute

global - if this element is a global element (complex type ref= to it, or in a part)

localSchema - the schema of the complex type containing the reference, only used for the 'odd case'.

elementSchema - the schema for the element.

Returns:

if the element needs to be qualified.

isComplexType

public static boolean isComplexType(org.apache.ws.commons.schema.XmlSchemaType type)

                                             org.apache.ws.commons.schema.XmlSchema schema)

isElementQualified

public static boolean isElementQualified(org.apache.ws.commons.schema.XmlSchemaElement element,
                                         boolean global,
                                         org.apache.ws.commons.schema.XmlSchema localSchema,
                                         org.apache.ws.commons.schema.XmlSchema elementSchema)

due to a bug, feature, or just plain oddity of JAXB, it isn't good enough to just check the form of an element and of its schema. If schema 'a' (default unqualified) has a complex type with an element with a ref= to schema (b) (default unqualified), JAXB seems to expect to see a qualifier, anyway.
So, if the element is local to a complex type, all we care about is the default element form of the schema and the local form of the element.
If, on the other hand, the element is global, we might need to compare namespaces.

Parameters:

element - the element.

global - if this element is a global element (complex type ref= to it, or in a part)

localSchema - the schema of the complex type containing the reference, only used for the 'odd case'.
