public static Variant.VARIANT toVariant(Object value)

Convert a java value into a VARIANT suitable for passing in a COM invocation.

Implementation Notes

  • VARIANTs are not rewrapped, but passed through unmodified
  • A string is wrapped into a BSTR, that is wrapped into the VARIANT. The string is allocated as native memory by the VARIANT constructor. The BSTR needs to be freed by com.sun.jna.platform.win32.OleAuto#SysFreeString.
Parameters
value:Object

to be wrapped

Returns:Variant.VARIANT

wrapped VARIANT
