Class Structure.FFIType

  • Enclosing class:

    static class Structure.FFIType
    extends Structure
    This class auto-generates an ffi_type structure appropriate for a given structure for use by libffi. The lifecycle of this structure is easier to manage on the Java side than in native code.
    • Method Detail

      • getFieldOrder

        protected List getFieldOrder()
        Description copied from class: Structure
        Return this Structure's field names in their proper order. For example,
         protected List getFieldOrder() {
             return Arrays.asList(new String[] { ... });
        IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.
         protected List getFieldOrder() {
             List fields = new ArrayList(super.getFieldOrder());
             fields.addAll(Arrays.asList(new String[] { ... }));
             return fields;
        Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.
        Specified by:
        getFieldOrder in class Structure
        ordered list of field names
      • get

        static Pointer get(Object obj)
        Obtain a pointer to the native FFI type descriptor for the given object.
