Method Details

name

FileSpec name(Generator<String> nameGenerator)

Description copied from interface: PathGeneratorSpec

Generator for the file or directory name.

Generated path names are formed using the following elements:

     [prefix][name][suffix]
 

• Prefix and suffix are optional and are null by default.
• If no generator is supplied using this method, a random 16-character lowercase name will be generated.
• The concatenation of prefix, name, and suffix must not be blank.

Example:

 List<Path> paths = Instancio.ofList(Path.class)
         .generate(all(Path.class), gen -> gen.nio().path()
                 .prefix("queued_")
                 .name(random -> random.alphanumeric(8))
                 .suffix(".csv"))
         .create();

 // Sample paths: queued_t5LG4AUw.csv, queued_o0nBWkej.csv, etc
