The
CreationPolicy is an AbstractPolicy that
handles the creation of content.
It handles the creation by initiating the adding of a content child to the
content parent via the ContentPolicy of the parent
IContentPart, as well as the attachment of anchored content elements
via the ContentPolicys of anchored IContentParts.
This policy should be registered at an IRootPart. It depends on
ContentPolicys being registered on all IContentParts that are
affected by the creation.

create
public IContentPart<? extends javafx.scene.Node> create(Object content, IVisualPart<? extends javafx.scene.Node> parent, int index, SetMultimap<IContentPart<? extends javafx.scene.Node>, String> anchoreds, boolean doFocus, boolean doSelect) Creates anIContentPartfor the given contentObjectand establishes parent and anchored relationships for the newly created part. Besides, operations are created for the establishment of the parent and anchored relationships within the content model. These operations are part of the operation returned byAbstractPolicy.commit().- Parameters:
content- The contentObjectto be created.parent- TheIContentPartwhere the content is added as a child or theIRootPartfor 'root' content.index- The index for the new element.anchoreds- TheIContentPartwhose content should be attached to the new content under the given roles.doFocus-trueif the newly created part should be focused.doSelect-trueif the newly created part should be selected.- Returns:
- The
IContentPartcontrolling the newly created content.

create
public IContentPart<? extends javafx.scene.Node> create(Object content, IVisualPart<? extends javafx.scene.Node> parent, SetMultimap<IContentPart<? extends javafx.scene.Node>, String> anchoreds) Creates anIContentPartfor the given contentObjectand establishes parent and anchored relationships for the newly created part. The respective content operations are also created. In case the given part is to be created for root contents, the root part is expected to be passed in as parent. The content will then be added to the viewer contents. Besides, operations are created for the establishment of the parent and anchored relationships within the content model. These operations are part of the operation returned byAbstractPolicy.commit().- Parameters:
content- The contentObjectto be created.parent- TheIContentPartwhere the content is added as a child.anchoreds- TheIContentPartwhose content should be attached to the new content under the given roles.- Returns:
- The
IContentPartcontrolling the newly created content.
-
createFocusOperation
protected ITransactionalOperation createFocusOperation(IContentPart<? extends javafx.scene.Node> part) Returns anITransactionalOperationthat adds the givenIContentPartto theFocusModelof the correspondingIViewer.- Parameters:
part- TheIContentPartthat is added to the viewer models.- Returns:
- An
ITransactionalOperationthat changes the viewer models.
-
createOperation
Description copied from class:AbstractPolicyCreates anITransactionalOperationthat is used to encapsulate the changes that are applied by thisAbstractPolicythrough its "work" methods. The created operation should allow forlocal executionat each time.- Specified by:
createOperationin classAbstractPolicy- Returns:
- A new
ITransactionalOperationto encapsulate all applied changes.
-
createSelectOperation
protected ITransactionalOperation createSelectOperation(IContentPart<? extends javafx.scene.Node> part) Returns anITransactionalOperationthat adds the givenIContentPartto theSelectionModelof the correspondingIViewer.- Parameters:
part- TheIContentPartthat is added to the viewer models.- Returns:
- An
ITransactionalOperationthat changes the viewer models.
-
getCompositeOperation
Extracts aAbstractCompositeOperationfrom the operation created bycreateOperation(). The composite operation is used to combine individual content change operations.- Returns:
- The
AbstractCompositeOperationthat is used to combine the individual content change operations.
-
getContentPartFactory
Returns theIContentPartFactoryof the current viewer.- Returns:
- the
IContentPartFactoryof the current viewer.
