public void add(YPersistenceManager pmgr,
                YIdentifier identifier)
         throws YPersistenceException

Adds an identifier to the collection.

Specified by:

add in interface YConditionInterface

Parameters:

identifier -

pmgr - an instantiated persistence manager object.

Throws:

YPersistenceException - if there's a problem persisting the change.

contains

public boolean contains(YIdentifier identifier)

Description copied from interface: YConditionInterface

Check whether a condition contains the specified identifier.

Specified by:

contains in interface YConditionInterface

Parameters:

identifier -

Returns:

true iff this contains identifier.

containsIdentifier

public boolean containsIdentifier()

Description copied from interface: YConditionInterface

Check whether a condition has at least one identifier.

Specified by:

containsIdentifier in interface YConditionInterface

Returns:

true iff this contains one or more identifier.

getAmount

public int getAmount(YIdentifier identifier)

Get the number of identifier matching the the one passed in.

Specified by:

getAmount in interface YConditionInterface

Parameters:

identifier -

Returns:

the number of equal identifiers in this.

getIdentifiers

public java.util.List<YIdentifier> getIdentifiers()

Description copied from interface: YConditionInterface

Get all the identifiers in a condition.

Specified by:

getIdentifiers in interface YConditionInterface

Returns:

a List of the identifiers in the condition numbering 1 or more.

removeOne

public YIdentifier removeOne(YPersistenceManager pmgr)
                      throws YPersistenceException

Specified by:

removeOne in interface YConditionInterface

Parameters:

pmgr - an instantiated persistence manager object.

Returns:

the identifier that has been removed.

Throws:

YPersistenceException - if there's a problem persisting the change.

removeOne

public void removeOne(YPersistenceManager pmgr,
                      YIdentifier identifier)
               throws YPersistenceException

Removes one YIdentifier equal to identifier from the condition. If there are none inside then make no change to the state of this.

Specified by:

removeOne in interface YConditionInterface

Parameters:

identifier -
