Enum MembershipType

java.lang.Object
  java.lang.Enum<MembershipType>
      edu.internet2.middleware.grouper.membership.MembershipType

All Implemented Interfaces:

Serializable, Comparable<MembershipType>

public enum MembershipType
extends Enum<MembershipType>

type of membership

IMMEDIATE

public static final MembershipType IMMEDIATE

An immediate member is directly assigned to a group. A composite group has no immediate members. Note that a member can have 0 to 1 immediate memberships to a single group, and 0 to many effective memberships to a group. A group can have potentially unlimited effective memberships

EFFECTIVE

public static final MembershipType EFFECTIVE

An effective member has an indirect membership to a group (e.g. in a group within a group). All subjects in a composite group are effective members (since the composite group has two groups and a set operator and no other immediate members). Note that a member can have 0 to 1 immediate memberships to a single group, and 0 to many effective memberships to a group. 'group within a group' can be nested to any level so long as it does not become circular. A group can have potentially unlimited effective memberships

COMPOSITE

public static final MembershipType COMPOSITE

composite memberships are due to union, intersection, minus A member of a group (aka composite member) has either or both of an immediate (direct) membership, or an effective (indirect) membership

NONIMMEDIATE

public static final MembershipType NONIMMEDIATE

everything except immediate An immediate member is directly assigned to a group. A composite group has no immediate members. Note that a member can have 0 to 1 immediate memberships to a single group, and 0 to many effective memberships to a group. A group can have potentially unlimited effective memberships

values

public static MembershipType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MembershipType c : MembershipType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MembershipType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

queryClause

public abstract String queryClause()

query clause for this membership type, e.g. = 'immediate'

Returns:

the query clause

getTypeString

public String getTypeString()

return the type string

Returns:

the type

valueOfIgnoreCase

public static MembershipType valueOfIgnoreCase(String string,
                                               boolean exceptionOnNull)

do a case-insensitive matching

Parameters:

string -

exceptionOnNull - will not allow null or blank entries

Returns:

the enum or null or exception if not found
