Interface Type

    • Method Detail

      • getName

        String getName()
        Returns the name of the type.
        Returns:
        the type name.

      • getURI

        String getURI()
        Returns the namespace URI of the type or null if the type has no URI (for example it was generated from a Schema with no target namespace).
        Returns:
        the namespace URI.

      • getInstanceClass

        Class getInstanceClass()
        Returns the Java class that this type represents.
        Returns:
        the Java class.

      • isInstance

        boolean isInstance​(Object object)
        Returns whether the specified object is an instance of this type.
        Parameters:
        object - the object in question.
        Returns:
        true if the object is an instance.
        See Also:
        Class.isInstance(java.lang.Object)

      • getProperties

        List getProperties()
        Returns the List of the Properties of this type.

        The expression 

           type.getProperties().indexOf(property)
        yields the property's index relative to this type. As such, these expressions are equivalent: 
            dataObject.get(i)
    dataObject.get((Property)dataObject.getType().getProperties().get(i));

        Returns:
        the Properties of the type.
        See Also:
        Property.getContainingType()

      • getProperty

        Property getProperty​(String propertyName)
        Returns from all the Properties of this type, the one with the specified name. As such, these expressions are equivalent: 
            dataObject.get("name")
    dataObject.get(dataObject.getType().getProperty("name"))

        Returns:
        the Property with the specified name.
        See Also:
        getProperties()

      • isDataType

        boolean isDataType()
        Indicates if this Type specifies DataTypes (true) or DataObjects (false). When false, any object that is an instance of this type also implements the DataObject interface. True for simple types such as Strings and numbers. For any object: 
           isInstance(object) && !isDataType() implies
   DataObject.class.isInstance(object) returns true.
        Returns:
        true if Type specifies DataTypes, false for DataObjects.

      • isOpen

        boolean isOpen()
        Indicates if this Type allows any form of open content. If false, dataObject.getInstanceProperties() must be the same as dataObject.getType().getProperties() for any DataObject dataObject of this Type.
        Returns:
        true if this Type allows open content.

      • isSequenced

        boolean isSequenced()
        Indicates if this Type specifies Sequenced DataObjects. Sequenced DataObjects are used when the order of values between Properties must be preserved. When true, a DataObject will return a Sequence. For example, 
          Sequence elements = dataObject.getSequence();
        Returns:
        true if this Type specifies Sequenced DataObjects.

      • isAbstract

        boolean isAbstract()
        Indicates if this Type is abstract. If true, this Type cannot be instantiated. Abstract types cannot be used in DataObject or DataFactory create methods.
        Returns:
        true if this Type is abstract.

      • getBaseTypes

        List getBaseTypes()
        Returns the List of base Types for this Type. The List is empty if there are no base Types. XSD , , and Java extends keyword are mapped to this list.
        Returns:
        the List of base Types for this Type.

      • getDeclaredProperties

        List getDeclaredProperties()
        Returns the Properties declared in this Type as opposed to those declared in base Types.
        Returns:
        the Properties declared in this Type.

      • getAliasNames

        List getAliasNames()
        Return a list of alias names for this Type.
        Returns:
        a list of alias names for this Type.

      • getInstanceProperties

        List getInstanceProperties()
        Returns a read-only List of instance Properties available on this Type.

        This list includes, at a minimum, any open content properties (extensions) added to the object before defining the Type's Type. Implementations may, but are not required to in the 2.1 version of SDO, provide additional instance properties.

        Returns:
        the List of instance Properties on this Type.
