A Lisp object.
A string or a symbol.
An association list.
make-lisp-proxy-with-overrides make a Lisp proxy, which is a Java proxy where method invocation ends up calling Lisp code. The result is a jobject proxy which represents the proxy, which can then be used in Java where an object that implements any of the interfaces that the proxy implements is required.
Note: The jobject is "local", which means that if it is generated in the scope of a call from Java it must be used (passed to Java method, return to the call from Java or pass it to jobject-ensure-global) in the scope of the call from Java. You cannot store it in Lisp and use it later (but you can do that with the result of jobject-ensure-global). If the jobject is generated not in the scope of a Java call, it must be used on the same thread that it was made.
name must be associated with a proxy definition, either by define-lisp-proxy or setup-lisp-proxy. The proxy definition determines which interfaces the proxy implements, and what happens when a method is invoked on the proxy. The processing of invocation of a method on the proxy is described in the entry for define-lisp-proxy.
user-data is an arbitrary object. It is passed to the Lisp function if the proxy definition specifies that it should be passed (keyword
:default-function-with-user-data for the default function).
print-name specifies the name of the proxy, after it is converted to a string by
cl:princ-to-string. If the proxy definition has a print-name too, the full print name of the proxy is formed by concatenating the definition's print-name and the proxy's print-name separated by " - ", otherwise the full print name is the proxy's print-name. The full print name is used when printing the proxy, and is also returned when the Java method
toString is applied to it. If print-name is
nil, a counter is used.
overrides, if supplied, must be an association list specifying overriding (see Overridesbelow), that is a list of conses where the
cl:car is the symbol to override and the
cl:cdr is the target. When overrides is non-nil overrides-plist is ignored.
make-lisp-proxy-with-overrides to override symbols in the proxy definition, which means that instead of calling the symbol in the proxy definition the target in the overrides is called. See the entry for define-lisp-proxy for details of the processing.
make-lisp-proxy-with-overrides is intended to make it simpler to use overrides. It is equivalent to calling
make-lisp-proxy with overrides-plist, and actually calls
make-lisp-proxy (so may get errors that look like they came from
make-lisp-proxy-with-overrides signal error if name is not associated with a proxy definition, and if any overrides are not of the right form or any of the functions to call is not a function designator. They may also signal an error if the proxy definition was not initialized and they failed to initialize it.
