Method Detail

addListener

public static void addListener(MTLTextGenerationListener listener)

Registers a listener to be notified for any text generation that will take place in this engine evaluation process. This will have to be removed manually through removeListener(MTLTextGenerationListener).

Parameters:

listener - The new listener that is to be registered for notification.

doGenerate

public static void doGenerate(java.util.Map<Module,java.util.Set<java.lang.String>> templates,
                              org.eclipse.emf.ecore.EObject model,
                              java.io.File generationRoot)

This can be used to launch the generation of multiple MTL templates given their names and their containing modules.

Keep in mind that this can only be used with single-argument templates. Any attempt to call to a template with more than one argument through this method will throw MTLEvaluationExceptions.

The input model will be iterated over for objects matching the templates' parameter types.

generationRoot will be used as the root of all generated files. For example, a template such as

 [template generate(c:EClass)]
 [file(log.log, true)]processing class [c.name/][/file]
 [/template]
 

evaluated with file:\\c:\ as generationRoot would create the file c:\log.log and generate a line "processing class <className>" for each class of the input model.

Parameters:

templates - This map will be used to locate templates of the given names in the associated module.

model - Input model for this generation.

generationRoot - This will be used as the root for the generated files. This can be null, in which case the user home directory will be used as root.

doGenerate

public static void doGenerate(Module module,
                              java.lang.String templateName,
                              org.eclipse.emf.ecore.EObject model,
                              java.io.File generationRoot)

Launches the generation of an MTL template given its name and containing module.

This is a convenience method that can only be used with single argument templates. The input model will be iterated over for objects matching the template's parameter type.

generationRoot will be used as the root of all generated files. For example, a template such as

 [template generate(c:EClass)]
 [file(log.log, true)]processing class [c.name/][/file]
 [/template]
 

evaluated with file:\\c:\ as generationRoot would create the file c:\log.log and generate a line "processing class <className>" for each class of the input model.

Parameters:

module - The module in which we seek a template templateName.

templateName - Name of the template that is to be generated.

model - Input model for this MTL template.

generationRoot - This will be used as the root for the generated files. This can be null, in which case the user home directory will be used as root.

doGenerate

public static void doGenerate(Module module,
                              java.lang.String templateName,
                              org.eclipse.emf.ecore.EObject model,
                              java.util.List<? extends java.lang.Object> arguments,
                              java.io.File generationRoot)

Launches the generation of an MTL template given its name and containing module.

This is a convenience method that can be used with multiple argument templates. The input model will be iterated over for objects matching the template's first parameter type. The template will then be called with these objects as first arguments, and the given list of arguments for the remaining template parameters.

generationRoot will be used as the root of all generated files. For example, a template such as

 [template generate(c:EClass)]
 [file(log.log, true)]processing class [c.name/][/file]
 [/template]
 

evaluated with file:\\c:\ as generationRoot would create the file c:\log.log and generate a line "processing class <className>" for each class of the input model.

Parameters:

module - The module in which we seek a template templateName.

templateName - Name of the template that is to be generated.

model - Input model for this MTL template.

arguments - Arguments of the template call, excluding the very first one (model object).

generationRoot - This will be used as the root for the generated files. This can be null, in which case the user home directory will be used as root.

doGenerate

public static void doGenerate(Template template,
                              org.eclipse.emf.ecore.EObject model,
                              java.io.File generationRoot)

Launches the generation of a single-argument MTL template for all matching EObjects in the given model.

This is a convenience method that can only be used with single argument templates. Any attempt at calling other templates through this method will throw MTLEvaluationExceptions. The input model will be iterated over for objects matching the template's parameter type.

generationRoot will be used as the root of all generated files. For example, a template such as

 [template generate(c:EClass)]
 [file(log.log, true)]processing class [c.name/][/file]
 [/template]
 

evaluated with file:\\c:\ as generationRoot would create the file c:\log.log and generate a line "processing class <className>" for each class of the input model.

Parameters:

template - The template that is to be generated

model - Input model for this MTL template.

generationRoot - This will be used as the root for the generated files. This can be null, in which case the user home directory will be used as root.

doGenerateTemplate

 [template generate(c:EClass)]
 [file(log.log, true)]processing class [c.name/][/file]
 [/template]

templateName - Name of the template that is to be generated.

arguments - Arguments that must be passed on to the template for evaluation.

generationRoot - This will be used as the root for the generated files. This can be null, in which case the user home directory will be used as root.
