Interface CreateFromTemplateDecorator

public interface CreateFromTemplateDecorator

Decorator for templating. The decorator will pre- or post-process the main file creation. Decorators are called by the infrastructure, in the declaration order, before the template file is processed and after it is processed, depending on CreateFromTemplateDecorator.isBeforeCreation() and CreateFromTemplateDecorator.isAfterCreation() return values. A decorator may perform both pre- and post- processing.

First the decorator is asked to CreateFromTemplateDecorator.accept(org.netbeans.api.templates.CreateDescriptor) the creation process; if it does not, it will not be invoked at all. Before/after main file creation the CreateFromTemplateDecorator.decorate(org.netbeans.api.templates.CreateDescriptor, java.util.List<org.openide.filesystems.FileObject>) method is called to perform its magic. Any reported additional files will be returned as part of FileBuilder.build() result.

Since:

1.9

Method Detail

isBeforeCreation

boolean isBeforeCreation()

Determines if the decorator should be called before template processing. Pre-decorators can setup the environment before the main file creation takes place.

Returns:

true, if the decorator should be called before template processing

isAfterCreation

boolean isAfterCreation()

Determines if the decorator should be called after template processing. Post-decorators can make additional (e.g. settings, registrations) adjustments.

Returns:

true, if the decorator should be called after template processing

accept

boolean accept(CreateDescriptor desc)

Determines whether the decorator is willing to participate in creation. If the decorator returns false, its CreateFromTemplateDecorator.decorate(org.netbeans.api.templates.CreateDescriptor, java.util.List<org.openide.filesystems.FileObject>) will not be called. It

Parameters:

desc - describes the request that is about to be performed

Returns:

true if this decorator wants to participate in files creation

decorate

@CheckForNull
List<FileObject> decorate(@NonNull
                                        CreateDescriptor desc,
                                        @NonNull
