Constructor Summary
`ListNotEqual()`

Method Summary
`boolean` | `bodyCall(Node[] args, int length, RuleContext context)` This method is invoked when the builtin is called in a rule body.
`int` | `getArgLength()` Return the expected number of arguments for this functor or 0 if the number is flexible.
`java.lang.String` | `getName()` Return a name for this builtin, normally this will be the name of the functor that will be used to invoke it.

Constructor Detail

### ListNotEqual

    public ListNotEqual()

Method Detail

### getName

    public java.lang.String getName()

  Return a name for this builtin, normally this will be the name of the functor that will be used to invoke it.

### getArgLength

    public int getArgLength()

  Return the expected number of arguments for this functor or 0 if the number is flexible.

  Specified by:
    `getArgLength` in interface `Builtin`
  Overrides:
    `getArgLength` in class `BaseBuiltin`

### bodyCall

    public boolean bodyCall(Node[] args,
                            int length,
                            RuleContext context)

  This method is invoked when the builtin is called in a rule body.

  Specified by:
    `bodyCall` in interface `Builtin`
  Overrides:
    `bodyCall` in class `BaseBuiltin`
  Parameters:
    `args` - the array of argument values for the builtin, this is an array of Nodes, some of which may be Node_RuleVariables.
    `length` - the length of the argument list, may be less than the length of the args array for some rule engines
    `context` - an execution context giving access to other relevant data
  Returns:
    return true if the buildin predicate is deemed to have succeeded in the current environment
