Method Detail

getInstance

public static DelegatingPolicy getInstance()

getExternalPermissionTypes

public Class<?>[] getExternalPermissionTypes()

setExternalPermissionTypes

public void setExternalPermissionTypes(Class<?>[] externalPermissionTypes)

getPermissions

public PermissionCollection getPermissions(ProtectionDomain domain)

Overrides:

getPermissions in class Policy

implies

public boolean implies(ProtectionDomain domain,
                       Permission permission)

Overrides:

implies in class Policy

getPermissions

public PermissionCollection getPermissions(CodeSource cs)

Return the permission collection associated with the cs. If there is no active JACC PolicyContext then the delegate value for getPermissions(CodeSource) is returned. Otherwise the JACC policy context permissions are returned.

Overrides:

getPermissions in class Policy

Parameters:

cs - - the CodeSource

Returns:

the associated permission collection

refresh

public void refresh()

We dynamically manage the active policies on commit so refresh is a noop. Its not clear from the spec whether committed policies should not be visible until a refresh.

Overrides:

refresh in class Policy

listContextPolicies

public String listContextPolicies()

Access the current ContextPolicy instances

Returns:

Map of the contextID to policy mappings

getPolicyProxy

public Policy getPolicyProxy()

Returns:

A proxy for our Policy interface

commit

public void commit(String contextID)
            throws PolicyContextException

May need to make this synchronized to allow the move from the open to active policy map atomic. Right now the assumption is that a single thread is active for a given contextID.

Parameters:

contextID -

Throws:

PolicyContextException

delete

public void delete(String contextID)
            throws PolicyContextException

Throws:

PolicyContextException
