LSPReferenceScope (LocalSolver 12.5 API)

java.lang.Object
- localsolver.modeler.LSPReferenceScope

All Implemented Interfaces:

java.lang.AutoCloseable
```
public class LSPReferenceScope
extends java.lang.Object
implements java.lang.AutoCloseable
```
A LSPReferenceScope contains a collection of references that can be released together. It simplifies the memory management of objects returned from the modeler API.

When you access a modeler object from the Java API, your Java program takes a new reference to that modeler object. These references are automatically deleted when the associated LSPModeler object is destroyed. But in the meantime references can prevent objects from being freed even if they are no longer used in the modeler. This is especially true if the interactions between the modeler and your LSP programs are complex and are not limited to a few exchanges at the beginning/end of the resolution.

In this case, a LSPReferenceScope allows you to limit the life of your references and can help you to preserve memory.

```
public LSPReferenceScope(LSPModeler modeler)
```
    Create a new LSPReferenceScope object associated with the modeler in parameter. All references created from that point anywhere in the API will be automatically associated with this new scope. All these references can then be released in one call to close() (or with a try-with-resources statement)
    
    Parameters:
    
    modeler - The associated modeler.
- Method Detail
  - close
```
public void close()
```
    Releases all references associated with this scope. It is also disassociated from the modeler and the previous scope is restored as the current one. If the scope has already been closed then this method do nothing and returns immediately.
    
    Note: Releasing a reference does not necessarily imply that the underlying modeler object is destroyed. It is only destroyed if no more references point to it.
