Class SDOTypeHelperDelegator

  • All Implemented Interfaces:
    TypeHelper, SDOTypeHelper
    public class SDOTypeHelperDelegator
extends AbstractHelperDelegator
implements SDOTypeHelper

    Purpose: Helper to provide access to declared SDO Types.

    Responsibilities:

    • Finds the appropriate SDOTypeHelperDelegate for the classLoader/application name and delegates work to that
    • Look up a Type given the uri and typeName or interfaceClass.
    • SDO Types are available through the getType("commonj.sdo", typeName) method.
    • Defines Types from DataObjects.

      • getType

        public Type getType​(String uri,
                    String typeName)
        Description copied from interface: TypeHelper
        Return the Type specified by typeName with the given uri, or null if not found. If the XSD uri (in the case of built-in Schema types) or the XSD typeName (in case an sdo:name annotation has been used) are different from the SDO name and uri (as returned by type.getURI()) and type.getName()), only the SDO uri and name are used for the lookup.
        If null or "" is passed as the value of the uri parameter, then a type with no URI will be returned, if found.
        Specified by:
        getType in interface TypeHelper
        Parameters:
        uri - The uri of the Type - type.getURI();
        typeName - The name of the Type - type.getName();
        Returns:
        the Type specified by typeName with the given uri, or null if not found.

      • getType

        public Type getType​(Class interfaceClass)
        Description copied from interface: TypeHelper
        Return the Type for this interfaceClass or null if not found.
        Specified by:
        getType in interface TypeHelper
        Parameters:
        interfaceClass - is the interface for the DataObject's Type - type.getInstanceClass();
        Returns:
        the Type for this interfaceClass or null if not found.

      • define

        public Type define​(DataObject dataObject)
        Description copied from interface: TypeHelper
        Define the DataObject as a Type. The Type is available through TypeHelper.getType(java.lang.String, java.lang.String) methods. If a type with the same name already exists, it is returned and no new definition takes place. If the uri property of the type to be defined is set to "", then the resulting type will have no uri, same as if the uri property was set to null.
        Specified by:
        define in interface TypeHelper
        Parameters:
        dataObject - the DataObject representing the Type.
        Returns:
        the defined Type.

      • define

        public List define​(List types)
        Description copied from interface: TypeHelper
        Define the list of DataObjects as Types. The Types are available through TypeHelper.getType(java.lang.String, java.lang.String) methods. The output list will contain, for every item in the input list, either the Type newly defined or a pre-existing Type in case a Type with the given name already exists, followed by any other types defined as a result of this call.
        Specified by:
        define in interface TypeHelper
        Parameters:
        types - a List of DataObjects representing the Types.
        Returns:
        the defined Types.

      • getWrappersHashMap

        public Map getWrappersHashMap()
        INTERNAL: Return the map of Wrapper objects (SDOWrapperTypes that wrap a primitive document).
        Specified by:
        getWrappersHashMap in interface SDOTypeHelper
        Returns:
        a HashMap of SDOWrapperTypes, keyed on the XSD type that it wraps.

      • setWrappersHashMap

        public void setWrappersHashMap​(Map aMap)
        INTERNAL: Set the map of Wrapper objects (SDOWrapperTypes that wrap a primitive document).
        Specified by:
        setWrappersHashMap in interface SDOTypeHelper
        Parameters:
        aMap - a HashMap of SDOWrapperTypes, keyed on the XSD type that it wraps.

      • defineOpenContentProperty

        public Property defineOpenContentProperty​(String uri,
                                          DataObject property)
        Description copied from interface: TypeHelper
        Define the DataObject as a Property for setting open content. The containing Type of the open content property is not specified by SDO. If the specified uri is not null the defined property is accessible through TypeHelper.getOpenContentProperty(uri, propertyName). If a null uri is specified, the location and management of the open content property is not specified by SDO.
        Specified by:
        defineOpenContentProperty in interface TypeHelper
        Parameters:
        uri - the namespace URI of the open content Property or null.
        Returns:
        the defined open content Property.

      • getOpenContentProperty

        public Property getOpenContentProperty​(String uri,
                                       String propertyName)
        Description copied from interface: TypeHelper
        Get the open content (global) Property with the specified uri and name, or null if not found. If the Schema name of the Property is different than its SDO name, only the SDO name is used for the lookup.
        If null or "" is passed as the value of the uri parameter, then a Property with no URI will be returned. (for example, a property mapped from a global element in an XSD with no target namespace)
        Specified by:
        getOpenContentProperty in interface TypeHelper
        Parameters:
        uri - the namespace URI of the open content Property.
        propertyName - the name of the open content Property.
        Returns:
        the global Property.

      • getPrefix

        public String getPrefix​(String uri)
        INTERNAL: Return the prefix for the given uri, or generate a new one if necessary
        Specified by:
        getPrefix in interface SDOTypeHelper
