Class AbstractRolesResolver

java.lang.Object

com.whitestein.lsps.orgstructure.model.resolver.AbstractRolesResolver

All Implemented Interfaces:

ParametricRolesResolver, RolesResolver

Direct Known Subclasses:

RecursiveDescentRolesResolver, StrictRolesResolver

public abstract class AbstractRolesResolver
extends java.lang.Object
implements ParametricRolesResolver

Provides a template for creating own roles resolvers.

The algorithm of the resolve(RoleUnit, Collection) template method does the following steps:

1. initializes the set of resolved role names
2. calls the overridden doResolve(com.whitestein.lsps.orgstructure.model.RoleUnit, java.util.Collection<com.whitestein.lsps.os.dto.RoleUnitParameter>) method
   • ...somewhere in the body the addRole(com.whitestein.lsps.orgstructure.model.Role, java.util.Collection<com.whitestein.lsps.os.dto.RoleUnitParameter>) method can be called...
3. returns the set of resolved role names

Method Detail

resolve

public final java.util.Set<RoleUnitName> resolve(RoleUnit roleUnit)

Description copied from interface: RolesResolver

Runs a resolving algorithm and returns a set of names of roles that were resolved from given roleUnit.

Specified by:

resolve in interface RolesResolver

Parameters:

roleUnit - The role or the organization unit to resolve.

Returns:

A set of names of roles that were resolved from given roleUnit.

resolve

public final java.util.Set<RoleUnitName> resolve(RoleUnit roleUnit,
                                                 java.util.Collection<RoleUnitParameter> parameters)

Description copied from interface: ParametricRolesResolver

Runs a resolving algorithm and returns a set of names of roles that were resolved from given roleUnit.

Specified by:

resolve in interface ParametricRolesResolver

Parameters:

roleUnit - The role or the organization unit to resolve.

parameters - The set of parameters to bind to each role or organization unit that is visited during resolution process.

Returns:

A set of names of roles that were resolved from given roleUnit.

addRole

protected final void addRole(Role role,
                             java.util.Collection<RoleUnitParameter> parameters)

Adds given role into the set of resolved roles.

It is best to call this method from within the overridden doResolve(RoleUnit, Collection) method body.

Parameters:

role - The role to add into the set.

parameters - The set of parameters to bind to each role or organization unit that is visited during resolution process.

Throws:

java.lang.NullPointerException - (unchecked) If role is null.

java.lang.IllegalStateException - (unchecked) If the internal set of roles is not initialized, probably because of calling this method from outside of the doResolve(RoleUnit, Collection) method.

doResolve

protected abstract void doResolve(RoleUnit roleUnit,
                                  java.util.Collection<RoleUnitParameter> parameters)

Runs actual roles resolving algorithm applied to given roleUnit.

Parameters:

roleUnit - The role or organization unit to resolve.

parameters - The set of parameters to bind to each role or organization unit that is visited during resolution process.
