- Super interfaces: `com.pnfsoftware.jeb.core.units.code.asm.type.INativeType`, `com.pnfsoftware.jeb.core.units.code.ICodePrototype`

A native prototype.  

  A prototype item contains return\- and parameter types, calling convention, as well as other  calling convention attributes.  

  Note: a reference\-item to a prototype\-item is a function\-pointer type.
