ChmodStrategy (omero-server 5.7.3 API)

All Known Implementing Classes:

GroupChmodStrategy
```
public interface ChmodStrategy
```
Strategy for changing the permissions of objects in the database as well as verifying that the permissions for the modified objects are sensible after the change. This interface is designed to be used in an asynchronous situation where as many individual steps as possible are performed rather than performing everything in one go.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`check(ome.model.IObject obj, java.lang.Object check)`	Performs one of the checks returned by `getChecks(IObject obj, String permissions)`.
`void`	`chmod(ome.model.IObject obj, java.lang.String permissions)`	Change the permissions for the given object.
`java.lang.Object[]`	`getChecks(ome.model.IObject obj, java.lang.String permissions)`	Return all the checks necessary to validate the given object if it were to have its permissions.

- Method Detail
  - getChecks
```
java.lang.Object[] getChecks(ome.model.IObject obj,
                             java.lang.String permissions)
```
    Return all the checks necessary to validate the given object if it were to have its permissions. The Object return value should be assumed opaque, and is primarily intended for passing it back to check(IObject, Object).
  - chmod
```
void chmod(ome.model.IObject obj,
           java.lang.String permissions)
```
    Change the permissions for the given object. This may do nothing if the permissions do not differ from the current settings. In any case, this method is intended to return quickly. Once the change takes place, it will be necessary to run check(IObject, Object) to guarantee that no invalid links are present.
  - check
```
void check(ome.model.IObject obj,
           java.lang.Object check)
```
    Performs one of the checks returned by getChecks(IObject obj, String permissions). These will typically be queries to be performed across all tables.
