Constructor Detail

SortedEnumByPrincipal

public SortedEnumByPrincipal(Enumeration source,
                             CollationKeyFactory key_factory)

Construct a sorted Enumeration containing the elements of another Enumeration. Elements are sorted into ascending order.

Supported API: true

Parameters:

source - source Enumeration

SortedEnumByPrincipal

public SortedEnumByPrincipal(Enumeration source,
                             CollationKeyFactory key_factory,
                             int order)

Construct a sorted Enumeration containing the elements of another Enumeration.

Supported API: true

Parameters:

source - source Enumeration

order - sort order (ASCENDING or DECENDING)

SortedEnumByPrincipal

public SortedEnumByPrincipal(Enumeration source,
                             boolean byFullName,
                             int order)

Construct a sorted Enumeration containing the WTPrincipals of another Enumeration.

Supported API: true

Parameters:

source - source Enumeration

byFullName - boolean to collate by FullName instead of Name attribute. If the elements are WTUsers, true will sort by FullName, else by web server id. If the elements are WTGroups, the sort will be by GroupName regardless.

order - sort order (ASCENDING or DECENDING)

Method Detail

hasMoreElements

public boolean hasMoreElements()

Supported API: true

Specified by:

hasMoreElements in interface Enumeration

nextElement

public Object nextElement()

Supported API: true

Specified by:

nextElement in interface Enumeration

size

public int size()

Return the number of elements remaining in the enumeration. Since each element of the underlying enumeration had to be accessed in order to sort them, the total number of elements is known.

Supported API: true

Returns:

number of elements remaining
