Java Mapping for Operations on Local Types

An operation on a local interface or a local class is mapped to a Java method with the same name. The mapping of operation parameters to Java is identical to the Client-Side Mapping for these parameters, in particular, when an operation has more than one return value and out parameters, the mapped Java method returns a generated Result object.

Unlike the Client-Side mapping, there is no mapped method with a trailing Context parameter.

For example:

Slice

module M
{
    local interface L; // forward declared
    local sequence<L> LSeq;
    local interface L
    {
        string op(int n, string s, LocalObject any, out int m, out string t, out LSeq newLSeq);
    }
}

is mapped to:

Java

package M;
 
public interface L
{
    public static class OpResult
    {
        public OpResult()
        {
        }

        public OpResult(String returnValue, int m, String t, L[] newLSeq)
        {
            this.returnValue = returnValue;
            this.m = m;
            this.t = t;
            this.newLSeq = newLSeq;
        }

        public String returnValue;
        public int m;
        public String t;
        public L[] newLSeq;
    }

    OpResult op(int n, String s, java.lang.Object any);
}
