Modifier and Type	Method and Description
`default PermissionMapper`	`and(PermissionMapper other)` Returns a new mapper where the `PermissionVerifier` created by this `PermissionMapper` is combined with the `PermissionVerifier` of the `other` `PermissionMapper` using 'and'.
`static PermissionMapper`	`createConstant(PermissionVerifier verifier)` Returns a new mapper that maps all to pre-defined `PermissionVerifier` instance.
`PermissionVerifier`	`mapPermissions(PermissionMappable permissionMappable, Roles roles)` Returns a `PermissionVerifier` with all the permissions associated with the given information.
`default PermissionMapper`	`or(PermissionMapper other)` Returns a new mapper where the `PermissionVerifier` created by this `PermissionMapper` is combined with the `PermissionVerifier` of the `other` `PermissionMapper` using 'or'.
`default PermissionMapper`	`unless(PermissionMapper other)` Returns a new mapper where the `PermissionVerifier` created by this `PermissionMapper` is combined with the `PermissionVerifier` of the `other` `PermissionMapper` using 'unless'.

```
static final PermissionMapper EMPTY_PERMISSION_MAPPER
```
    A default implementation that does nothing but returns an empty and read-only PermissionVerifier.
- Method Detail
  - mapPermissions
```
PermissionVerifier mapPermissions(PermissionMappable permissionMappable,
                                  Roles roles)
```
    Returns a PermissionVerifier with all the permissions associated with the given information.
    Once returned, client code can use the PermissionVerifier.implies(Permission) to check if a given permission is granted or not to the given principal. Implementors must make sure that the returned collection is immutable.
    
    Parameters:
    
    permissionMappable - the object to which permissions can be mapped (must not be null)
    
    roles - a set of effective roles after all role mapping was applied by security domain (may be null)
    
    Returns:
    
    a permission verifier (not null)
  - and
```
default PermissionMapper and(PermissionMapper other)
```
    Returns a new mapper where the PermissionVerifier created by this PermissionMapper is combined with the PermissionVerifier of the other PermissionMapper using 'and'.
    
    Parameters:
    
    other - the other PermissionMapper to combine with this PermissionMapper
    
    Returns:
    
    the combined PermissionMapper
  - or
```
default PermissionMapper or(PermissionMapper other)
```
    Returns a new mapper where the PermissionVerifier created by this PermissionMapper is combined with the PermissionVerifier of the other PermissionMapper using 'or'.
    
    Parameters:
    
    other - the other PermissionMapper to combine with this PermissionMapper
    
    Returns:
    
    the combined PermissionMapper
  - xor
```
default PermissionMapper xor(PermissionMapper other)
```
    Returns a new mapper where the PermissionVerifier created by this PermissionMapper is combined with the PermissionVerifier of the other PermissionMapper using 'xor'.
    
    Parameters:
    
    other - the other PermissionMapper to combine with this PermissionMapper
    
    Returns:
    
    the combined PermissionMapper
  - unless
```
default PermissionMapper unless(PermissionMapper other)
```
    Returns a new mapper where the PermissionVerifier created by this PermissionMapper is combined with the PermissionVerifier of the other PermissionMapper using 'unless'.
    
    Parameters:
    
    other - the other PermissionMapper to combine with this PermissionMapper
    
    Returns:
    
    the combined PermissionMapper
  - createConstant
```
static PermissionMapper createConstant(PermissionVerifier verifier)
```
    Returns a new mapper that maps all to pre-defined PermissionVerifier instance.
    
    Parameters:
    
    verifier - the PermissionVerifier that will be returned for anybody.
    
    Returns:
    
    the constant PermissionVerifier
