public Generator()

Method Detail

annotations

public Collection<Class<? extends Annotation>> annotations()

load

public void load(ProcessingEnvironment processingEnv)

filename

public String filename(M model)

Generate the file name for the model.

When the returned value

• is null, no file is created
• does not contain / and ends with .java, the file is created as a source file by the annotation processor and the class will be compiled by the current compilation process
• starts with the resources/ prefix, the file is created as a resource file by the annotation processor using the remaining suffix value and the file will likely end in the classes directory
• otherwise the resource will be created as a file on the filesystem, a value not starting with / is created relative to the codegen.output directory

Parameters:

model - the model

Returns:

the filename or null if no generation should happen

render

public String render(M model,
                     int index,
                     int size,
                     Map<String,Object> session)

Render the model

Parameters:

model - the model

index - the index for an incremental generator

size - the number of models for an incremental generator

session - the session

Returns:

the rendered string or null
