Detailed Description

An abstract engine to produce a lot of similar values.

This can be often used for simple (often immutable) types. Such types are built from some properties, don't depend on the current context and don't change often. An example of usage are colors, fonts, etc.

Events are not handled by this engine and the changes to the context are simply accepted.

Source

If this is built from a property or from a component, its value or name respectively is used as the type.

Attributes

• type: overwrites the type from the source

Author:

kma

Parameters:

<T>	The type of the attributes

String metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.getAttributeType

(

)

Gets the type attribute.

Returns:

The type or null

static Set<String> metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.getAttributeTypes

(

)

[static]

Returns the set of supported attribute types.

Returns:

The unmodifiable set of types

abstract AttributeBuilder<T> metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.getBuilder

(

String

type

)

[protected, pure virtual]

Gets a builder for a given type.

Parameters:

type	The type or null

Returns:

The builder or null

abstract AttributeBuilder<T> metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.getDefaultBuilder

(

String

type

)

[protected, pure virtual]

Gets a default builder for a given type.

Parameters:

type	The type or null

Returns:

The builder

void metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.initActionHander

(

)

[protected]

Registers the attribute handlers for events (actions).

Reimplemented from metadone.client.grasyla2.GrasylaEngine.

final boolean metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.isNativeAttribute

(

String

name

)

[protected]

Indicates whether an attribute is handled when building the component.

In other words, a native attribute should not be handled by an attribute handler.

Parameters:

name	The name of the attribute

Returns:

true if name is a native attribute

Reimplemented from metadone.client.grasyla2.GrasylaEngine.

void metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.notifyChildChanged	(	Engine	child,
		ChildComponent	comp
	)		[protected]

Reimplemented from metadone.client.grasyla2.GrasylaEngine.

References metadone.client.grasyla2.GrasylaEngine.ChildComponent.getAttribute().

final void metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.rebuildComponent

(

)

throws BadPreCondition [protected]

Rebuilds the component.

This is nearly the same as refresh, but the children are kept; only the current component is rebuilt.

Exceptions:

BadPreCondition

See also:

refresh()

Component<?> metadone.client.grasyla2.base.GrasylaEngineForAttribute< T >.updateToConcreteObject

(

ConcreteObjectGroupChange

event

)

[protected]

Called when the object group has been changed.

This method MUST be overwritten completely when setCanUpdateObject(boolean) is set to true.

Parameters:

event

The event

Returns:

The new component

Reimplemented from metadone.client.grasyla2.GrasylaEngine.
