* Include this file in order for C/C++ enums to be wrapped by proper Java enums.
* Note that the JNI layer handles the enum as an int. The Java enum has extra
* code generated to store the C++ int value. This is required for C++ enums that
* specify a value for the enum item, as native Java enums do not support this.

/*
* SwigNext static inner class used instead of a static int as static fields cannot be accessed from enum initialisers.
* The swigToEnum method is used to find the Java enum from a C++ enum integer value. The default one here takes
* advantage of the fact that most enums do not have initial values specified, so the lookup is fast. If initial
* values are specified then a lengthy linear search through all possible enums might occur. Specific typemaps could be
* written to possibly optimise this lookup by taking advantage of characteristics peculiar to the targeted enum.
