## Query or set the internal variable that controls how integer classes are
## converted when Java matrix autoconversion is enabled.  When enabled, Java
## arrays of class Byte or Integer are converted to matrices of class uint8 or
## uint32 respectively.
## 
## When called from inside a function with the "local" option, the variable is
## changed locally for the function and any subroutines it calls.  The original
## variable value is restored when exiting the function.
