Interface CustomInstanceFactory

public interface CustomInstanceFactory

Creates instance of the desired class based on the file. Module providers may register factories to control creation of instances from files that use only file name or instanceClass attribute.

Registered factories are called in the registration order, until one provides a non-null result, which become the file's created instance. If all factories return null, the FileSystems API will create the instance using the default constructor.

Module implementors are encouraged to use the instanceCreate attribute instead.
