Enum NativeType

All Implemented Interfaces:
Serializable, Comparable<NativeType>

public enum NativeType extends Enum<NativeType>
NativeType defines the primitive types supported internally. Usually you will not use these types directly, and should instead use the standard types such as Pointer, NativeLong, or any of the normal java types such as int, short. All other types are defined in terms of these primitive types.
  • Enum Constant Details

    • VOID

      public static final NativeType VOID
      Void type. Only used for function return types.
    • SCHAR

      public static final NativeType SCHAR
      Signed char. Equivalent to a C char or signed char type. Usually 1 byte in size.
    • UCHAR

      public static final NativeType UCHAR
      Unsigned char. Equivalent to a C unsigned char type. Usually 1 byte in size
    • SSHORT

      public static final NativeType SSHORT
      Signed short integer. Equivalent to a C short or signed short type. Usually 2 bytes in size.
    • USHORT

      public static final NativeType USHORT
      Unsigned short integer. Equivalent to a C unsigned short type. Usually 2 bytes in size.
    • SINT

      public static final NativeType SINT
      Signed integer. Equivalent to a C int or signed int type. Usually 4 bytes in size.
    • UINT

      public static final NativeType UINT
      Unsigned integer. Equivalent to a C unsigned int type. Usually 4 bytes in size.
    • SLONG

      public static final NativeType SLONG
      Signed long integer. Equivalent to a C long or signed long type. Can be either 4 or 8 bytes in size, depending on the platform.
    • ULONG

      public static final NativeType ULONG
      Unsigned long integer. Equivalent to a C unsigned long type. Can be either 4 or 8 bytes in size, depending on the platform.
    • SLONGLONG

      public static final NativeType SLONGLONG
      Signed long long integer. Equivalent to a C long long or signed long long type. Usually 8 bytes in size.
    • ULONGLONG

      public static final NativeType ULONGLONG
      Unsigned long long integer. Equivalent to a C unsigned long long type. Usually 8 bytes in size.
    • FLOAT

      public static final NativeType FLOAT
      Single precision floating point. Equivalent to a C float type. Usually 4 bytes in size.
    • DOUBLE

      public static final NativeType DOUBLE
      Double precision floating point. Equivalent to a C double type. Usually 8 bytes in size.
    • STRUCT

      public static final NativeType STRUCT
      Native struct type
    • ADDRESS

      public static final NativeType ADDRESS
      Native memory address. Equivalent to a C void* or char* pointer type. Can be either 4 or 8 bytes in size, depending on the platform.

  • Method Details

    • values

      public static NativeType[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static NativeType valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
