Class MethodDescriptor

java.lang.Object

org.ojalgo.concurrent.MethodDescriptor

All Implemented Interfaces:

Serializable

public final class MethodDescriptor
extends Object
implements Serializable

Description of a (static) method to invoke in a child JVM. Uses type names internally to avoid ClassLoader mismatches.

In Java, a method is identified for reflective lookup by its name and parameter types only. The return type is not used to resolve a method and cannot disambiguate overloads (two methods cannot differ only by return type).

Method Details

of

public static MethodDescriptor of(Class<?> owner,
 String name,
 Class<?>... parameters)

of

public static MethodDescriptor of(Method method)

Create a descriptor from a reflective Method. Parameter types are taken as declared (including varargs represented as an array type). The return type is intentionally not included as it is not used for reflective lookup.

The method must be static when used with ExternalProcessExecutor.
