+--javax.media.jai.CollectionOp
A node in a CollectionImage chain. A CollectionOp
stores an operation name, a ParameterBlock containing sources
and parameters, and a RenderingHints containing hints which
may be used in rendering the node. A set of nodes may be joined together
via the source Vectors within their respective
ParameterBlocks to form a directed acyclic
graph (DAG). The topology, i.e., connectivity, of the graph may be
altered by changing the node's sources. The operation name, parameters,
and rendering hints may also be changed. A CollectionOp may
be used in either the rendered or the renderable mode for
Collections, i.e., "collection" or "renderableCollection"
mode, respectively.
A CollectionOp may be constructed directly as, for example,
Collection srcCol;
double[] constants;
ParameterBlock pb =
(new ParameterBlock()).addSource(srcCol).add(constants);
CollectionOp node =
new CollectionOp("addConstToCollection", pb, null);
or by the createCollection or createCollectionNS()
"collection" mode methods or the createRenderableCollection()
or createRenderableCollectionNS() "renderableCollection" mode
methods defined in the JAI class. The difference between
direct construction of a node and creation via a convenience method is that
in the latter case:
CollectionImage, a RenderedImage
("collection" mode only), or a RenderableImage
("renderableCollection" mode only).RenderingHints maintained by the JAI
instance are merged with the local RenderingHints with the
local hints taking precedence.validateArguments() method of the associated
OperationDescriptor, the arguments (sources and parameters)
are validated as being compatible with the specified operation in
the appropriate mode.CollectionOp is
created; otherwise any source Collections are
"unwrapped" until a valid argument list is obtained or it is
determined that such is impossible.
isImmediate() method of the corresponding
OperationDescriptor returns true)
then the node is rendered. When a chain of nodes is rendered by any means a "parallel" chain of
CollectionImages is created. Each node in the chain of
CollectionOps corresponds to a node in the chain of
CollectionImages. Collection methods invoked
on the CollectionOp are in general forwarded to the associated
CollectionImage which is referred to as the rendering
of the node. The rendering of the node may be a rendered or renderable
CollectionImage, i.e., eventually contain
RenderedImages or RenderableImages, respectively,
depending on the mode in which the node is used.
The translation between CollectionOp chains and
CollectionImage chains makes use of two levels of
indirection provided by the OperationRegistry and either the
CollectionImageFactory (CIF) or the
RenderableCollectionImageFactory (RCIF) facilities.
First, the local OperationRegistry is used to map the
operation name into a CIF or RCIF. This factory then constructs
a CollectionImage. The local
OperationRegistry is used in order to take advantage
of the best possible implementation of the operation.
A node may be rendered explicitly by invoking the method
getCollection() which also returns the rendering of the
node. A node may be rendered implicitly by invoking any method
defined in the Collection interface. A rendering of a
node may also be obtained by means of the createInstance()
method. This method returns a Collection rendering without
marking the node as having been rendered. If the node is not
marked as rendered then it will not fire
CollectionChangeEvents as described below.
CollectionOp nodes may participate in Java Bean-style
events. The PropertyChangeEmitter methods may be used
to register and unregister PropertyChangeListeners.
CollectionOps are also PropertyChangeListeners
so that they may be registered as listeners of other
PropertyChangeEmitters or the equivalent. Each
CollectionOp also automatically receives any
CollectionChangeEvents emitted by any of its sources which
are also CollectionOps and RenderingChangeEvents
from any RenderedOp sources.
Certain PropertyChangeEvents may be emitted by the
CollectionOp. These include the
PropertyChangeEventJAIs and
PropertySourceChangeEvents required by virtue of implementing
the OperationNode interface. Additionally a
CollectionChangeEvent may be emitted if the node is
operating in the "collection" mode, has already been rendered, and one of
the following conditions is satisfied:
CollectionChangeEvent from one of
its CollectionOp sources or a RenderingChangeEvent
from one if its RenderedOp.CollectionImage will be generated by the
OperationRegistry for the new operation.
CollectionImage by invoking update() on the
CollectionImageFactory which generated it. If this attempt
fails, a new CollectionImage for this operation will be
requested from the OperationRegistry.CollectionChangeEvent will be fired to all registered
listeners of the "Collection" PropertyChangeEvent and to all
sinks which are PropertyChangeListeners. The new and old
values set on the event object correspond to the previous and current
CollectionImages, respectively, associated with this node. CollectionOp nodes are WritablePropertySources
and so manage a name-value database of image meta-data also known as image
properties. Properties may be set on and requested from a node. The
value of a property not explicitly set on the node (via
setProperty()) is obtained from the property environment of
the node. When a property is derived from the property environment it is
cached locally to ensure synchronization, i.e., that properties do not
change spontaneously if for example the same property is modified upstream.
The property environment of a CollectionOp is initially
derived from that of the corresponding OperationDescriptor
as maintained by the OperationRegistry. It may be modified
locally by adding PropertyGenerators, directives to copy
certain properties from specific sources, or requests to suppress certain
properties. These modifications per se cannot be undone directly but
may be eliminated as a side effect of other changes to the node as
described below.
When a property value is requested an attempt will be made to derive it from the several entities in the following order of precedence:
PropertySource;PropertyGenerators, or
setProperty() or due to caching of a
property derived from the property environment.
All dynamically computed properties of a CollectionOp which
have been cached locally, i.e., those cached properties which were not set
by an explicit call to setProperty(), will be cleared when any
of the critical attributes of the node is edited. By implication these
properties will also be cleared when a CollectionChangeEvent
is received from any node source. The property environment or the cached
properties may also be cleared by invoking resetProperties().
