addConstraintMapping

public void addConstraintMapping(ConstraintMapping mapping)

Description copied from interface: ConstraintAware

Add a Constraint Mapping. May be called for running webapplication as an annotated servlet is instantiated.

Specified by:

addConstraintMapping in interface ConstraintAware

Parameters:

mapping - the mapping

See Also:

ConstraintAware.addConstraintMapping(org.eclipse.jetty.security.ConstraintMapping)

addRole

public void addRole(String role)

Description copied from interface: ConstraintAware

Add a Role definition. May be called on running webapplication as an annotated servlet is instantiated.

doStop

protected void doStop()
               throws Exception

processConstraintMapping

protected void processConstraintMapping(ConstraintMapping mapping)

Create and combine the constraint with the existing processed constraints.

Parameters:

mapping - the constraint mapping

processConstraintMappingWithMethodOmissions

protected void processConstraintMappingWithMethodOmissions(ConstraintMapping mapping,
                                                           Map<String,RoleInfo> mappings)

Constraints that name method omissions are dealt with differently. We create an entry in the mappings with key "<method>.omission". This entry is only ever combined with other omissions for the same method to produce a consolidated RoleInfo. Then, when we wish to find the relevant constraints for a given Request (in prepareConstraintInfo()), we consult 3 types of entries in the mappings: an entry that names the method of the Request specifically, an entry that names constraints that apply to all methods, entries of the form <method>.omission, where the method of the Request is not named in the omission.

Parameters:

mapping - the constraint mapping

mappings - the mappings of roles

configureRoleInfo

protected void configureRoleInfo(RoleInfo ri,
                                 ConstraintMapping mapping)

Initialize or update the RoleInfo from the constraint

Parameters:

ri - the role info

mapping - the constraint mapping

prepareConstraintInfo

protected RoleInfo prepareConstraintInfo(String pathInContext,
                                         Request request)

Find constraints that apply to the given path. In order to do this, we consult 3 different types of information stored in the mappings for each path - each mapping represents a merged set of user data constraints, roles etc -:

1. A mapping of an exact method name
2. A mapping with key * that matches every method name
3. Mappings with keys of the form "<method>.<method>.<method>.omission" that indicates it will match every method name EXCEPT those given
