## Class IntegerType

- java.lang.Object
- - java.lang.Number
  - - com.sun.jna.IntegerType

- All Implemented Interfaces:
    NativeMapped, java.io.Serializable
  Direct Known Subclasses:
    BaseTSD.DWORD_PTR, BaseTSD.LONG_PTR, BaseTSD.ULONG_PTR, NativeLong, OaIdl.VARIANT_BOOL, Structure.FFIType.size_t, WinDef.BOOL, WinDef.CHAR, WinDef.DWORD, WinDef.DWORDLONG, WinDef.INT_PTR, WinDef.LONG, WinDef.LONGLONG, WinDef.SHORT, WinDef.UCHAR, WinDef.UINT, WinDef.UINT_PTR, WinDef.ULONG, WinDef.ULONGLONG, WinDef.USHORT, WinDef.WORD

      public abstract class IntegerType
      extends java.lang.Number
      implements NativeMapped

  Represents a native integer value, which may have a platform-specific size (e.g. `long` on unix-based platforms). May optionally indicate an unsigned attribute, such that when a value is extracted into a larger-sized container (e.g. `int` retrieved via `Number.longValue()`, the value will be unsigned. Default behavior is signed.
