Usage:

<DD><B>java::field</B> ?<B>-noconvert</B>? <I>objOrClass field</I> ?<I>value field value ...</I>?

<P>

The <B>java::field</B> command is used to manipulate accessible fields from
Tcl. The <I>objOrClass</I> argument specifies either a fully qualified
name of the declaring class of the field to access, or an object
handle. The <I>field</I> argument specifies which field to
manipulate.  If an additional <I>value</I> parameter exists,
then the field will be set to <I>value</I>, otherwise
the current value of the field is returned.  Multiple fields may be
set via additional parameters by alternating field signatures and
values. To access a shadowed field in a superclass, a full field
signature consisting of the field name followed by the superclass
name must be provided as the <I>field</I> argument.

Examples:

<DD>

The <B>java::field</B> command can be used to get the value of
a static class variable. In this example, we query the
static variable <B>java.lang.Integer.MAX_VALUE</B>, which
has the value 2147483647.

<P>

<code>
<pre>
% java::field Integer MAX_VALUE
2147483647

</pre>
</code>

<P>

The <B>java::field</B> command can be used to set the value of
an instance field. In this example, it is assumed that
the class APublic has a public <B>java.lang.String</B> field
named foo. The value is queried after being set.

<P>

<code>
<pre>
% set obj [java::new APublic]
% java::field $obj foo bar
% java::field $obj foo
bar
</pre>
</code>

<P>

The <B>java::field</B> command also supports getting the compiler
simulated <B>class</B> field for a Class. This is the preferred method
of getting a handle to a <code>java.lang.Class</code>
object given a class name.

<P>

<code>
<pre>
% set cl [java::field java.util.Hashtable class]
% java::info class $cl
java.lang.Class

</pre>
</code>
