Method Detail

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in class DBManEvent

Returns:

true if no BOs were modified

getSize

public int getSize()

Returns:

the number of BOs modified by this event, zero if there are no changes.

getBO

public BO getBO(int i)

Returns:

the BO modified with index i from this event. Parameter is limited to 0...getSize()-1

getBOId

public long getBOId(int i)

Returns:

the Id of the BO with index i from this event. Parameter is limited to 0...getSize()-1

getBOClass

public java.lang.Class getBOClass(int i)

Returns:

the Class of the BO with index i from this event. Parameter is limited to 0...getSize()-1

isOneOfClass

public boolean isOneOfClass(java.lang.Class clazz)

Tells if this event concerns an object of the given class (including subclasses).

Parameters:

clazz - The class of which we want objects of.

Returns:

true if at least one of the objects that this event concerns is of the given clazz or a subclass thereof, false otherwise.

isOneOfClasses

public boolean isOneOfClasses(java.lang.Class[] clazzes)

Tells if this event concerns an object of one of the given classes (including subclasses).

Parameters:

clazzes - The classes of which we want objects of.

Returns:

true if at least one of the objects that this event concerns is one of the given clazzes or a subclass thereof, false otherwise.

getBOIdsForClass

public java.util.List<java.lang.Long> getBOIdsForClass(java.lang.Class _clazz)

Returns the BO-Ids of this event matching the passed class.

Parameters:

_clazz - return only BO-Ids of this class (including subclasses)

Returns:

an ArrayList with the BO-Ids of this event matching the criteria.

getBOIdsForClasses

public java.util.List<java.lang.Long> getBOIdsForClasses(java.lang.Class[] _clazzes)

Returns the BO-Ids of this event matching any of the passed classes.

Parameters:

_clazzes - return only BO-Ids of these classes (including subclasses)

Returns:

an ArrayList with the BO-Ids of this event matching the criteria.

getBOs

public java.util.List<BO> getBOs(BOLoaderI _bol)

Loads and returns the BOs of this event.

Parameters:

_bol - the BOLoaderI which should be used for loading the BOs.

_clazz - if given/not null tells that only BOs of this class (including subclasses) should be loaded and returned; if not given/null all BOs will be loaded.

onlyChanged - return only BOs which were actually changed

Returns:

an ArrayList with the BOs of this event.

getBOs

public java.util.List<BO> getBOs(BOLoaderI _bol,
                                 java.lang.Class _clazz)
