Class SCDResolver

java.lang.Object

org.apache.xerces.impl.scd.SCDResolver

public class SCDResolver
extends Object

Implements XML Schema: Component Designators (SCD) Currently, this implementation has following limitations
1. the Schema Step is not supported
2. the axis types; Extension axis, Assertions axis, Alternative axis, Context axis
are not supported
3. Extension accessors are not supported
4. the top level Identity Constraint Definitions components are not supported.
5. all the other Schema 1.1 constructs that are not listed here, are not supported.
6. the schemaAttribute axis does not work as it is expected in the specification.
7. in some situations, the SCPs that have been reduced by the elided-componet axis do not
produce expected results
8. the fundamental facets are not supported (but the constraining facets are supported).

SCDResolver

public SCDResolver(XSModel xsModel)

Constructor

Parameters:

xsModel - the schema description schema component

Method Detail

resolve

public XSObjectList resolve(String relativeSCD)
                     throws SCDException

Resolves a relative SCD against the schema description schema component (i.e. the XSModel).

Parameters:

relativeSCD - the input relative SCD string in the form of,
[5] RelativeSchemaComponentDesignator ::= XmlnsPointerPart* XscdPointerPart
e.g. xmlns(p=http://www.example.com/schema/po)xscd(/type::p:SKU/facet::pattern)

Returns:

a list of XML schema components that are designated by the SCD, otherwise and empty XSObjectList

Throws:

SCDException

resolve

public XSObjectList resolve(String scp,
                   NamespaceContext nsContext)
                     throws SCDException

Resolves an SCP against the schema description schema component (i.e. the XSModel).

Parameters:

scp - the input SCP to designate the components.
e.g. /type::p:SKU/facet::pattern

nsContext - namespace context details for the component names used in the SCP string

Returns:

a list of XML schema components that are designated by the SCP, otherwise and empty XSObjectList

Throws:

SCDException

resolve

public XSObjectList resolve(String incompleteSCP,
                   NamespaceContext nsContext,
                   XSObject currentComponent)
                     throws SCDException

Resolves an incomplete SCP against a given schema component

Parameters:

incompleteSCP - the incomplete SCP. To emphasize the incompleteness of such paths, the current component step syntax may be used (.) for the head step. For example, if the initial source component is a complex type, the following paths are equivalent and designate the element declaration with the QName my:section within the sequence model group of that type:
model::sequence/schemaElement::my:section
./model::sequence/schemaElement::my:section

nsContext - namespace context details for the component names used in the incomplete SCP string

currentComponent - the initial source component

Returns:

the list of schema components that are designated by the incomplete SCP, otherwise an empty XSObjectList.

Throws:

SCDException

resolve

public XSObjectList resolve(String incompleteSCD,
                   XSObject currentComponent)
                     throws SCDException

Resolves an incomplete SCD against a given schema component

Parameters:

incompleteSCD - the incomplete SCD string. which is in the form of
[5] RelativeSchemaComponentDesignator ::= XmlnsPointerPart* XscdPointerPart
but XscdPointerPart contains an incomplete SCP instead of a complete SCP.
e.g. xmlns(p=http://www.example.com/schema/po)xscd(./type::p:SKU/facet::pattern) or xmlns(p=http://www.example.com/schema/po)xscd(type::p:SKU/facet::pattern)
i.e. an incomplete SCP must not start with a '/'.

currentComponent - the initial source component

Returns:

the list of schema components that are designated by the incomplete SCP, otherwise an empty XSObjectList.

Throws:

SCDException

toString

public String toString()
