Description

The functions setup-java-caller and setup-java-constructor define a Java caller, which is a function that calls a Java method or a constructor. Once this the caller is defined, calls to name ultimately invoke the Java method or constructor.

Interpretation of class-name, method-name, signatures, static-p, return-jobject, non-virtual-p and class-symbol and the behavior of the defined caller is the same as the macros define-java-caller and define-java-constructor.

Unlike the macros define-java-caller and define-java-constructor. the functions setup-java-caller and setup-java-constructor do the lookup immediately, and therefore require running Java. If the lookup fails, they do not set the symbol function, and return two values: nil and a condition indicating the reason for the failure.

The functions (when successful) return name.
