ListMapAsSubject (Apache Jena)

java.lang.Object
- org.apache.jena.reasoner.rulesys.builtins.BaseBuiltin
- - org.apache.jena.reasoner.rulesys.builtins.ListMapAsSubject

All Implemented Interfaces:

Builtin
```
public class ListMapAsSubject
extends BaseBuiltin
```
For each element in the RDF list (first argument) it asserts triples with that as the subject and predicate and object given by arguments two and three. A strange and hacky function, only usable in the head of forward rules.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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.
`void`	`headAction(Node[] args, int length, RuleContext context)`	This method is invoked when the builtin is called in a rule head.

  - 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
  - headAction
```
public void headAction(Node[] args,
                       int length,
                       RuleContext context)
```
    This method is invoked when the builtin is called in a rule head. Such a use is only valid in a forward rule.
    
    Specified by:
    
    headAction in interface Builtin
    
    Overrides:
    
    headAction in class BaseBuiltin
    
    Parameters:
    
    args - the array of argument values for the builtin, this is an array of Nodes.
    
    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
