- Method Detail
  - getName
```
java.lang.String getName()
```
    Returns:
    
    printable name of the resource.
  - getParent
```
IResource getParent()
```
    Gets next resource in the hierarchy. Call hasParent first to make sure there is one.
    
    Returns:
    
    Resource parent (or IllegalStateException if there is none). Never a null.
  - hasParent
```
boolean hasParent()
```
    Indicates whether or not this resource has a parent in the hierarchy. Please perform this check before calling getParent() method.
    
    Returns:
    
    Whether or not the resource has a parent.
  - exists
```
boolean exists()
```
    Returns:
    
    Whether or not this resource exists in Cassandra.
  - applicablePermissions
```
java.util.Set<Permission> applicablePermissions()
```
    Returns the set of Permissions that may be applied to this resource Certain permissions are not applicable to particular types of resources. For instance, it makes no sense to talk about CREATE permission on table, or SELECT on a Role. Here we filter a set of permissions depending on the specific resource they're being applied to. This is necessary because the CQL syntax supports ALL as wildcard, but the set of permissions that should resolve to varies by IResource.
    
    Returns:
    
    the permissions that may be granted on the specific resource
