Mapped Java Class

A Slice local interface is mapped to a Java interface with the same name, for example:

Slice

[["java:package:com.zeroc"]]
 
module Ice
{
    local interface Communicator
    {
        ...
    }
}

is mapped to the Java interface Communicator:

Java

package com.zeroc.Ice;
 
public interface Communicator
{
    ...
}

The delegate metadata allows you to map a local interface with a single operation to a functional Java interface. For example:

Slice

[["java:package:com.zeroc"]]
module Ice
{
    ["delegate"] local interface ValueFactory
    {
        Value create(string type);
    }
}

is mapped to:

Java

package com.zeroc.Ice;
 
@FunctionalInterface
public interface ValueFactory
{
    com.zeroc.Ice.Value create(String type);
}

LocalObject in Java

All Slice local interfaces implicitly derive from LocalObject, which is mapped to java.lang.Object in Java.

Inheritance of local Slice interfaces is mapped to interface inheritance in Java. For example:

Slice

module M
{
    local interface A {}
    local interface B extends A {}
    local interface C extends A {}
    local interface D extends B, C {} 
}

is mapped to:

Java

package M;
 
public interface A {}
public interface B extends A {}
public interface C extends A {}
public interface D extends B, C {}
