# GetJointThresholdCallbackTargets(Allocator)

> Get all current PhysicsWorld.jointThresholdEvents where either of the PhysicsJoint involved are valid (see PhysicsJoint.isValid ) and have a callback target assigned (see PhysicsJoint.callbackTarget ).

## Definition

```csharp
public PhysicsCallbacks.JointThresholdCallbackTargets GetJointThresholdCallbackTargets(Allocator allocator = Allocator.Temp)
```

### Parameters

**** (\[Allocator]\(/engine/6000.3/script-reference/unity/collections/allocator)): The memory allocator to use for the results. This can only be [Allocator.Temp](/engine/6000.3/script-reference/unity/collections/allocator/temp.md), [Allocator.TempJob](/engine/6000.3/script-reference/unity/collections/allocator/tempjob.md) or [Allocator.Persistent](/engine/6000.3/script-reference/unity/collections/allocator/persistent.md).

### Returns

| Type                                                                                                                                             | Description                                                                                                                                                  |

| [JointThresholdCallbackTargets](/engine/6000.3/script-reference/unityengine/lowlevelphysics2d/physicscallbacks/jointthresholdcallbacktargets.md) | The joint callback target results. This must be disposed of after use otherwise leaks will occur. The exception to this is if there are no targets returned. |
