getInstance

public static AccessControlManager getInstance()

init

public void init()

reloadProperties

public void reloadProperties()

propertiesChange

public void propertiesChange(JProperties properties)

Description copied from interface: JPropertiesListener

Invoked after properties have been modified in JCMS and save on disk.

You cannot alter the value received in parameters.

Specified by:

propertiesChange in interface JPropertiesListener

Parameters:

properties - the properties which have been modified (may not contain all JCMS properties)

initBeforeStoreLoad

public void initBeforeStoreLoad()
                         throws java.lang.Exception

Description copied from class: ChannelListener

Called just before the store has been loaded. If for any reason you want to interrupt JCMS startup, you can throw an exception. The exception's message will be displayed in JCMS status page (to any user!).

Specified by:

initBeforeStoreLoad in class ChannelListener

Throws:

java.lang.Exception - any exception you may want to throw if a problem occurs needing to interrupt JCMS startup.

initAfterStoreLoad

public void initAfterStoreLoad()
                        throws java.lang.Exception

Description copied from class: ChannelListener

Called just after the store has been loaded and the channel has been initialized. If for any reason you want to interrupt JCMS startup, you can throw an exception. The exception's message will be displayed in JCMS status page (to any user!).

Specified by:

initAfterStoreLoad in class ChannelListener

Throws:

java.lang.Exception - any exception you may want to throw if a problem occurs needing to interrupt JCMS startup.

handleFinalize

public void handleFinalize()

Description copied from class: ChannelListener

Called when the channel is finalized

Specified by:

handleFinalize in class ChannelListener

getDeclaredResources

public java.util.Set<java.lang.String> getDeclaredResources()

Retrieve the resources declared in properties.

Returns:

a Set of resource path.

getValidResources

public java.util.Set<java.lang.String> getValidResources()

Retrieve the resources allowed to be accessed (those declared in properties and the associated zone).

Returns:

a Set of resource path.

checkAccess

public boolean checkAccess(Member member,
                  java.lang.String resource,
                  java.util.Map<java.lang.String,java.lang.Object> context)

Check if the specified member is authorized to access the specified resource.

A valid context map containing the current Workspace is required for all access check on workspace resources (eg resource starting with "admin-ws/" as defined by "admin-ws".
Use utility method for easier invocation :

  boolean isAuthorized = AccessControlManager.checkAccess(loggedMember, "admin-ws/types/content", AccessControlUtil.getContext(workspace));
 

A valid context map containing the current Data being edited is required for all access to data resource (as declared in properties). Use utility method for easier invocation :

  Map aclContext = AccessControlUtil.getContext(null, AccessControlConstants.CTXT_DATA, someMemberBeingEdited);
  boolean isAuthorized = AccessControlManager.checkAccess(loggedMember, "admin/users/member", aclContext);
 

Parameters:

member - a Member

resource - a resource URI using a path representation, eg "admin/dev/store-cleaner"

context - an optional context map containing relevant information such as workspace or data

Returns:

true if the access is authorized, false otherwise

internalCheckWorkspaceDataAccess

protected static boolean internalCheckWorkspaceDataAccess(java.lang.String resource,
                                       Group aclGroup,
                                       Workspace ws,
