Looping through Hashmap in JavaScript

[Prvz Khan]

I am using Rhino 1.7 to run javascript.
I am creating Hashmap using java.util.HashMap.

function fn(x)
{

}

In the above function fn, I am getting this Hashmap as arguments. How can iterate over this hashmap?

Object.keys(x) not giving correct output.

From the decafjs AWS module, see the Iterator() use:

function instanceInfo(instance) {
    var securityGroups = [];
    for (var group in Iterator(instance.getSecurityGroups())) {
        securityGroups.push(String(group.getGroupName()));
    }
    var tags = [];
    for (var tag in Iterator(instance.getTags())) {
        tags.push({
            key   : String(tag.getKey()),
            value : String(tag.getValue())
        });
    }

    return {
        architecture          : String(instance.getArchitecture()),
        clientToken           : String(instance.getClientToken()),
        ebsOptimized          : !!instance.getEbsOptimized(),
        hypervisor            : String(instance.getHypervisor()),
        amiId                 : String(instance.getImageId()),
        instanceId            : String(instance.getInstanceId()),
        instanceType          : String(instance.getInstanceType()),
        keyName               : String(instance.getKeyName()),
        launchTime            : new Date(instance.getLaunchTime().getTime()),
        platform              : String(instance.getPlatform()),
        privateDnsName        : String(instance.getPrivateDnsName()),
        privateIpAddress      : String(instance.getPrivateIpAddress()),
        publicDnsName         : String(instance.getPublicDnsName()),
        publicIpAddress       : String(instance.getPublicIpAddress()),
        ramdiskId             : String(instance.getRamdiskId()),
        rootDeviceName        : String(instance.getRootDeviceName()),
        rootDeviceType        : String(instance.getRootDeviceType()),
        securityGroups        : securityGroups,
        state                 : String(instance.getState().getName()),
        stateReason           : String(instance.getStateReason() ? instance.getStateReason().getMessage() : null),
        stateTransitionReason : String(instance.getStateTransitionReason()),
        tags                  : tags
    };
}

Hi mschwartz,

The solution I wanted mustn't include any outside modules. I want native solution of JavaScript runnable by Rhino Engine.

Although I got the solution:
function fn(x) {

        var enteries = modList.entrySet().iterator();

        while (enteries.hasNext()) {
            var ok = enteries.next();
            print('' + ok.getKey() + ' -> ' + ok.getValue() + '\n');
        }
}

Thanks

Did typo in previous post:

--var enteries = modList.entrySet().iterator();
++var enteries = x.entrySet().iterator();

[Mike Schwartz]

Iterator() is built into rhino.  It requires no outside modules.
