IntegerType (JNA API)

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

All Implemented Interfaces:

NativeMapped, Serializable

Direct Known Subclasses:

BaseTSD.DWORD_PTR, BaseTSD.LONG_PTR, BaseTSD.ULONG_PTR, NativeLong, Structure.FFIType.size_t, WinDef.DWORD, WinDef.DWORDLONG, WinDef.INT_PTR, WinDef.LONG, WinDef.UINT_PTR, WinDef.ULONG, WinDef.ULONGLONG, WinDef.WORD
```
public abstract class IntegerType
extends 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.
