create

public static final <TT> Collection<TT> create(Collection<TT> collection,
                                               int targetResultCount,
                                               long cutOffAfterTimeMs,
                                               int cutOffAfterCount)

Helper method to create a PermissionCheckCollection from an existing Collection

Type Parameters:

TT - the type of the Collection

Parameters:

collection - the Collection to proxy

targetResultCount - the desired number of results or default to the collection size

cutOffAfterTimeMs - the number of milliseconds to wait before cut-off or zero to use the system default time-based cut-off.

cutOffAfterCount - the number of permission checks to process before cut-off or zero to use the system default count-based cut-off.

Returns:

a Collection of the same type but including the PermissionCheckCollection interface
