  - - org.apache.jena.reasoner.rulesys.impl.GenericTripleMatchFrame

Direct Known Subclasses:

ConsumerChoicePointFrame, TripleMatchFrame
```
public class GenericTripleMatchFrame
extends GenericChoiceFrame
```
Frame on the choice point stack used to represent the state of some form of triple match - this is either a direct graph query or a query to a cached set of results.
This is used in the inner loop of the interpreter and so is a pure data structure not an abstract data type and assumes privileged access to the interpreter state.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`bindResult(Triple triple, LPInterpreter interpreter)`	Bind the goal variables to the given result triple.
`boolean`	`functorMatch(Triple t, LPInterpreter interpreter)`	Check that the object of a triple match corresponds to the given functor pattern.
`void`	`init(LPInterpreter interpreter)`	Initialize the triple match to preserve the current context of the given LPInterpreter and search for the match defined by the current argument registers

- Method Detail
  - bindResult
```
public boolean bindResult(Triple triple,
                          LPInterpreter interpreter)
```
    Bind the goal variables to the given result triple. Returns false if the triple doesn't match the goal (due to a functor match failure).
  - functorMatch
```
public boolean functorMatch(Triple t,
                            LPInterpreter interpreter)
```
    Check that the object of a triple match corresponds to the given functor pattern. Side effects the variable bindings.
  - init
```
public void init(LPInterpreter interpreter)
```
    Initialize the triple match to preserve the current context of the given LPInterpreter and search for the match defined by the current argument registers
    
    Overrides:
    
    init in class GenericChoiceFrame
    
    Parameters:
    
    interpreter - the interpreter instance whose env, trail and arg values are to be preserved
