public class AttributeTypeBuilder
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.

This method resets all state after the attribute is built.
protected String typeName()
public GeometryType buildGeometryType()
This method resets all state after the attribute is built.
public AttributeDescriptor buildDescriptor(String name)
If crs
has been set via setCRS(CoordinateReferenceSystem)
the internal attribute type will be built via buildGeometryType()
,
otherwise it will be built via buildType()
.
This method calls through to buildDescriptor(String, AttributeType)
.

- The name of the descriptor.buildDescriptor(String, AttributeType)
public AttributeDescriptor buildDescriptor(String name, AttributeType type)
Internal state is reset after the descriptor is built.

- The type referenced by the descriptor.public GeometryDescriptor buildDescriptor(String name, GeometryType type)
Internal state is reset after the descriptor is built.
