Calling Java from Prolog

• javaMethod(+ClassOrInstance, +Method, -Return) Invoke a Java method, where
  • ClassOrInstance is either an atom that represents a Java class's name, or a term $addr(I1,I2) that represents a Java object. Java objects are passed to Prolog from Java . It is meaningless to construct an object term by any other means.

  • Method: is an atom or a structure in the form f(t1,...,tn) where f is the method name, and t1,...,tn are arguments.

  • Return: is a variable that will be bound to the returned object by the method.

• javaMethod(+ClassOrInstance, +Method) The same as javeMethod/3 but does not require a return value.

• javaGetField(+ClassOrInstance, +Field, -Value) Get the value of Field of ClassOrInstance and bind it to Value. A field must be must be an atom.

• javaSetField(+ClassOrInstance, +Field, +Value) Set Field of ClassOrInstance to be Value.
