Class ResultList

java.lang.Object
  com.sapportals.wcm.rfadapter.ResultList

public final class ResultList

extends Object

a simple container that only allows to add, not to remove instances of the Result class. It holds a global list containing all instances as well as seperate lists only holding instances of a ceratin Status category. See class Status for available categories. This container should be used, when operations of the rfadapter package are used for a list of IResources in a single transaction (e.g. the user selected a list of resources for a copy operation). The loop calling the rfadpter-operations can add all returned Result instances to this container.

Method Detail

add

public void add(Result result)

adds the given instance to the list of all results. Depending on the Status of the result, it is also added to the according list that only contains results of this status-category. As the Result class will never return null for its status, each result will be placed in one of the categories available. So the addition of the entries in each of the sublists will yield the same number of elements as the total list of elements.

Parameters:

result - the instance to add. If the parameter is null, it will not be added

getStatus

public Status getStatus()

Returns:

the "worst" status of any result that has been added. The Status.NONE is not considered here. If the list of a status contains at least one element, this status determines the status of this ResultList instance. If the list of this status does not hold any elements the next status will be considered. The order of asking the lists is determined by the severity of the status.

get

public Result get(int index)

Parameters:

index - the position of the Result instance to retrieve

Returns:

the Result at the given position

size

public int size()

Returns:

the number of the Result instances stored in this container

sublist

public ResultList sublist(Status status)

Parameters:

status - the status to retrieve the Results of. Must not be null

Returns:

a new ResultList instance that only holds Result instances of the given status category. If the current instance does not hold any instances of the Result class with this severity, the returned list will also hold no instances. The number of elements in the total list of the returned ResultList will naturally match the number of elements in its sublist of the given status category
