  • Method Details

    • getDescriptor

      public PropertyDescriptor getDescriptor(Name name)
      Description copied from interface: ComplexType
      Describe a single property by name.

      This method returns null if no such property is found.

      Specified by:
      getDescriptor in interface ComplexType
      Parameters:
      name - The name of the property to get.
      Returns:
      The property matching the specified name, or null.

    • getDescriptor

      public PropertyDescriptor getDescriptor(String name)
      Description copied from interface: ComplexType
      Describe a single property by unqualified name.

      Note: Special care should be taken when using this method in the case that two properties with the same local name but different namespace uri exist. For this reason using ComplexType.getDescriptor(Name) is safer.

      This method returns null if no such property is found.

      Specified by:
      getDescriptor in interface ComplexType
      Parameters:
      name - The name of the property to get.
      Returns:
      The property matching the specified name, or null.

    • getDescriptors

      public Collection<PropertyDescriptor> getDescriptors()
      Description copied from interface: ComplexType
      The property descriptor which compose the complex type.

      A complex type can be composed of attributes and associations which means this collection returns instances of AttributeDescriptor and AssociationDescriptor.

      Specified by:
      getDescriptors in interface ComplexType
      Returns:
      Collection of descriptors representing the composition of the complex type.

    • isInline

      public boolean isInline()
      Description copied from interface: ComplexType
      Indicates ability of XPath to notice this attribute.

      This facility is used to "hide" an attribute from XPath searches, while the compelx contents will still be navigated no additional nesting will be considered. It will be as if the content were "folded" inline resulting in a flatter nesting structure.

      Construct described using Java Interfaces: 

      
 interface TestSample {
     String name;
     List measurement;
 }
 interface Measurement {
     long timestamp;
     Point point;
     long reading;
 }
      The above is can hold the following information: 
      
 [ name="survey1",
   measurements=(
       [timestamp=3,point=(2,3), reading=4200],
       [timestamp=9,point=(2,4), reading=445600],
   )
 ]
      Out of the box this is represented to XPath as the following tree: 
      
 root/name: survey1
 root/measurement[0]/timestamp:3
 root/measurement[0]/point: (2,3)
 root/measurement[0]/reading: 4200
 root/measurement[1]/timestamp:9
 root/measurement[2]/point: (2,4)
 root/measurement[3]/reading: 445600
      By inlining Measurement we can achive the following: 
      
 root/name: survey1
 root/timestamp[0]:3
 root/point[0]: (2,3)
 root/reading[0]: 4200
 root/timestamp[1]:9
 root/point[1]: (2,4)
 root/reading[1] 445600
      Specified by:
      isInline in interface ComplexType
      Returns:
      true if attribute is to be considered transparent by XPath queries

    • getBinding

      public Class<Collection<Property>> getBinding()
      Description copied from interface: PropertyType
      The java class that values of properties of the property type are bound to.

      This value is never null.

      Specified by:
      getBinding in interface ComplexType
      Specified by:
      getBinding in interface PropertyType
      Overrides:
      getBinding in class AttributeTypeProxy
      Returns:
      The binding of the property type.
