org.geotools.feature.TypeBuilder

Makes building types easier by maintaining state.

For reference the builder captures the following state:

State		Property				Complex	Feature		Builder
scope	state	descriptor()	attribute()	geometry()	association()	complex()	feature()	collection()	init()	reset()	clear()
naming	namespace	x	x	x	x	x	x	x	x
	name	x	x	x	x	x	x	x	x	x
	isIdentified		x	x	x	x	x	x	x
	description		x	x	x	x	x	x	x	x
type	isAbstract		x	x	x	x	x	x	x
	superType		x	x	x	x	x	x	x
	restriction*		x	x	x	x	x	x	x
association	referenceType				x				x
descriptor	minOccurs	x							x		x
	maxOccurs	x							x		x
	isNillable	x							x		x
	propertyType	x							x
atomic	binding		x	x					x
complex	properties*					x	x	x	x	x
spatial	crs			x			x	x	x
spatial	defaultGeom						x	x	x	x
collection	members*							x	x	x

* collection implementation may be specified

There are five state control methods:

{@link init( PropertyType )} - completly load settings from type
{@link init( PropertyDescriptor )} - completly load settings from descriptor
{@link init()} - completly replace settings with builder defaults
- {@link reset()} - called after a type creation methods to reset common type settings
- {@link clear()} - called after an descriptor create method (or add methods) to clear commondescriptor settings

For examples of using this class please see the following type creation methods:

{@link attribute()}
{@link geometry()}
{@link association()}
{@link complex()}
{@link feature()}
{@link collection()}
