FindParentsI

public FindParentsI(ome.security.ACLVoter aclVoter,
                    ome.system.Roles securityRoles,
                    ome.services.graphs.GraphPathBean graphPathBean,

                    ome.services.graphs.GraphPolicy graphPolicy)

Construct a new find-parents request; called from GraphRequestFactory.getRequest(Class).

Parameters:

aclVoter - ACL voter for permissions checking

securityRoles - the security roles

graphPathBean - the graph path bean to use

adminPrivileges - the light administrator privileges helper

targetClasses - legal target object classes for the search

graphPolicy - the graph policy to apply for the search

Method Detail

getCallContext

public java.util.Map<java.lang.String,java.lang.String> getCallContext()

Description copied from interface: IRequest

Returns the desired call context for this request. Some request implementations will require "omero.group":"-1" for example and will hard-code that value. Others may permit users to pass in the desired values which will be merged into the static Map as desired.

Specified by:

getCallContext in interface IRequest

Returns:

the call context for this request

init

public void init(Helper helper)

Description copied from interface: IRequest

Method called within the transaction boundaries before any processing occurs. Implementations must properly initialize the "step" field of the Status object by calling Helper.setSteps(int). This count will define how many times the IRequest.step(int) method will be called. The Helper instance passed in contains those resources needed by IRequests to interact with data and should be stored for later use.

Specified by:

init in interface IRequest

Parameters:

helper - the helper for this request

step

public java.lang.Object step(int step)
                      throws HandleI.Cancel

Description copied from interface: IRequest

Single uncancellable action which will be performed by this IRequest. The return value can be an ome.model object that is attached to the current thread and transaction. After processing and detachment from the transaction, the object will be passed to IRequest.buildResponse(int, Object) for conversion and storage.

Specified by:

step in interface IRequest

Parameters:

step - the step number

Returns:

an object to be used in building the response

Throws:

HandleI.Cancel - if this request is cancelled

finish

public void finish()

Description copied from interface: IRequest

Method within the transaction boundaries after all processing has occurred. A thrown HandleI.Cancel will still rollback the current transaction.

Specified by:

finish in interface IRequest

buildResponse

public void buildResponse(int step,
                          java.lang.Object object)

Description copied from interface: IRequest

Post-transaction chance to map from the return value of IRequest.step(int) to a Response object.

Specified by:

buildResponse in interface IRequest

Parameters:

step - the step number

object - an object to be used in building the response

getResponse

public Response getResponse()

Description copied from interface: IRequest

Returns the current response value. This method should be protected by synchronization where necessary, and should never raise an exception. It is also guaranteed to be called so that any state cleanup that is necessary can take place here.

Specified by:

getResponse in interface IRequest

Returns:

the response to this request

isReadOnly

public boolean isReadOnly(ome.services.util.ReadOnlyStatus readOnly)

Specified by:

isReadOnly in interface ome.services.util.ReadOnlyStatus.IsAware
