Class AttributeTypeBuilder

  • public class AttributeTypeBuilder
extends Object
    Builder for attribute types and descriptors.

    Building an attribute type: 

     
  //create the builder
  AttributeTypeBuilder builder = new AttributeTypeBuilder();

  //set type information
  builder.setName( "intType" ):
  builder.setBinding( Integer.class );
  builder.setNillable( false );

  //build the type
  AttributeType type = builder.buildType();

    Building an attribute descriptor: 

     
  //create the builder
  AttributeTypeBuilder builder = new AttributeTypeBuilder();

  //set type information
  builder.setName( "intType" ):
  builder.setBinding( Integer.class );
  builder.setNillable( false );

  //set descriptor information
  builder.setMinOccurs(0);
  builder.setMaxOccurs(1);
  builder.setNillable(true);

  //build the descriptor
  AttributeDescriptor descriptor = builder.buildDescriptor("intProperty");

    This class maintains state and is not thread safe.

      • namespaceURI

        protected String namespaceURI
        namespace used to distingish between otherwise identical type names.

      • isAbstract

        protected boolean isAbstract
        abstract flag

      • restrictions

        protected List<Filter> restrictions
        restrictions

      • isIdentifiable

        protected boolean isIdentifiable
        identifiable flag

      • binding

        protected Class<?> binding
        bound java class

      • defaultValue

        protected Object defaultValue
        default value

      • isDefaultValueSet

        protected boolean isDefaultValueSet

      • isCrsSet

        protected boolean isCrsSet

      • minOccurs

        protected Integer minOccurs
        Minimum number of occurrences allowed. See minOccurs() function for the default value based on nillable if not explicitly set.

      • maxOccurs

        protected Integer maxOccurs
        Maximum number of occurrences allowed. See maxOccurs() function for the default value (of 1).

      • isNillable

        protected boolean isNillable
        True if value is allowed to be null.

        Depending on this value minOccurs, maxOccurs and defaultValue() will return different results.

        The default value is true.

      • length

        protected Integer length
        If this value is set an additional restriction will be added based on the length function.

      • userData

        protected Map<Object,​Object> userData
        User data for the attribute.

    • Constructor Detail

      • AttributeTypeBuilder

        public AttributeTypeBuilder()
        Constructs the builder.

      • AttributeTypeBuilder

        public AttributeTypeBuilder​(FeatureTypeFactory factory)
        Constructs the builder specifying the factory used to build attribute types.
