|
|
* 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.
|
|
* The special variable, $enumvalues, is replaced with a comma separated list of all the enum values.
