Class KeyValuePair

java.lang.Object
  sleep.bridges.KeyValuePair

public class KeyValuePair
extends java.lang.Object

Arguments passed to functions with the form key => expression are available via the KeyValuePair object. The following is the implementation of the built-in function &hash(key => "value", key2 => 3, ...):

 class hash implements Function
 {
    public Scalar evaluate(String n, ScriptInstance si, Stack arguments)
    {
       Scalar value = SleepUtils.getHashScalar();

       while (!arguments.isEmpty())
       {
          KeyValuePair kvp = BridgeUtilities.getKeyValuePair(arguments);

          Scalar blah = value.getHash().getAt(kvp.getKey());
          blah.setValue(kvp.getValue());
       }

       return value;
    }
 }
