* Signature Construction Macros
** These macros can be used to construct signature strings. Hopefully their names
** are a little easier to remember than the single character they correspond to.
** For example, to specify the signature of the method:
** public int read(byte b[], int off, int len);
** you could write something like this in C:
** char* readSig = JRISigMethod(JRISigArray(JRISigByte)
** JRISigInt
** JRISigInt) JRISigInt;
** Of course, don't put commas between the types.
#define JRISigArray(T) "[" T
#define JRISigByte "B"
#define JRISigChar "C"
#define JRISigClass(name) "L" name ";"
#define JRISigFloat "F"
#define JRISigDouble "D"
#define JRISigMethod(args) "(" args ")"
#define JRISigNoArgs ""
#define JRISigInt "I"
#define JRISigLong "J"
#define JRISigShort "S"
#define JRISigVoid "V"
#define JRISigBoolean "Z"

* Specific Scalar Array Types
** The JRI Native Method Interface does not support boolean arrays. This
** is to allow Java runtime implementations to optimize boolean array
** storage. Using the ScalarArray operations on boolean arrays is bound
** to fail, so convert any boolean arrays to byte arrays in Java before
** passing them to a native method.
