Class JSGFPLib

java.lang.Object
  SecuGen.FDxSDKPro.jni.JSGFPLib

public class JSGFPLib
extends java.lang.Object

This class is the main entrypoint to the SecuGen device and algorithm functionality. When the JSGFPLib class is instantiated, it loads the JNISGFPLIB library which in turn calls the functions in the SecuGen SGFPLIB library. These libraries are required in the system path before the JSGFPLib class can be used.

Field Summary

Constructor Summary

JSGFPLib()
Creates a new instance of JSGFPLib.

Field Detail

jniLoadStatus

public long jniLoadStatus

SecuGen JNI library initialization status. This variable is populated when the JSGFPLib open() method is called. For any values other than SGFDxError.ERROR_NONE, the library is in an unstable state.
Possible values:
♦ SGFDxErrorCode.ERROR_NONE
♦ SGFDxErrorCode.SGFDX_ERROR_JNI_DLLLOAD_FAILED
