Class AttributeTypeBuilder

Object
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.

      protected List<Filter> restrictions
      restrictions

    • description

      protected InternationalString description
      string description

    • isIdentifiable

      protected boolean isIdentifiable
      identifiable flag

    • binding

      protected Class<?> binding
      bound java class

    • superType

      protected AttributeType superType
      super type

    • defaultValue

      protected Object defaultValue
      default value

    • isDefaultValueSet

      protected boolean isDefaultValueSet

    • crs

      protected CoordinateReferenceSystem crs

    • 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.

    • ff

      protected FilterFactory ff

  • Constructor Details

    • AttributeTypeBuilder

      public AttributeTypeBuilder()
      Constructs the builder.

    • AttributeTypeBuilder

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