Interface ClassFile

public sealed interface ClassFile

ClassFile is a preview API of the Java platform.

Programs can only use ClassFile when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

Represents a context for parsing, transforming, and generating classfiles. A ClassFile has a set of options that condition how parsing and generation is done.
