jautoUnwrap

Unwrap automatically returned values

Calling Sequence

autoUnwrap = jautoUnwrap()
jautoUnwrap(autoUnwrap)

Parameters

autoUnwrap

A boolean

Description

If autoUnwrap is true, all the values returned by a method invocation are unwrapped if it is possible.

This strongly simplifies the usage of the Java / Scilab conversions.

By default, autoUnwrap is true.

Examples

jautoUnwrap(%f);
jautoUnwrap()
jautoUnwrap(%t);
// In this example, without disabling the auto unwrap, Scilab will try to
// convert the result of currentTimeMillis to a long (which is not yet
// supported in Scilab)
// Without the auto unwrap, Scilab will keep a reference to the object

               jautoUnwrap(%f)
               jimport java.util.Date;
               jimport java.lang.System;

               t = System.currentTimeMillis();
               s = jnewInstance(Date, t);
               str = jnewInstance("java.lang.String", "Hello");
               d = s.toString()

               jremove Date System t s str;
               jautoUnwrap(%t)
