org.alfresco.repo.virtual.store.TemplateVirtualizationMethod

All Implemented Interfaces:

VirtualizationMethod

Direct Known Subclasses:

AspectVirtualizationMethod, TypeVirtualizationMethod

public abstract class TemplateVirtualizationMethod
extends Object
implements VirtualizationMethod

Base implementation for virtualization rules defined using template located in the content repository or in a system path.
System paths are custom string references of a resource that can be located either in the repository or in the java classpath - system paths are deprecated and they will be replaced by Encodings.PLAIN encoded Reference strings.
Templates are programmatic or declarative definitions of the rules implemented by this virtualization method.
Supported template formats include JavaScript defined templates and JSON defined templates (JSON templates are also referred as vanilla templates). The extension present in the name of the template is used to determine the nature of the template (*.js for JavaScript and *.json for JSON).
JSON templates processing is done using a configurable JavaScriot processor script (actually a JavaScript template that gets an extra parameter containing the JSON template) that resides in the Java class path.
Templates are processed in order to virtualize NodeRefs using NewVirtualReferenceMethod protocol reference constructor visitor.
