Filter bundle collisions hook method. This method is called during the
install or update operation. The operation type will be
#INSTALLING or
#UPDATING. Depending
on the operation type the target module and the collision candidate
collection are the following:
-
#INSTALLING - The target is the module associated
which is performing the install operation. The
collision candidate collection contains the existing modules installed
which have a current revision with the same symbolic name and version as the
module being installed.
-
#UPDATING - The target is the module being updated.
The collision candidate collection contains the existing modules installed which have
a current revision with the same symbolic name and version as the content the target
module is being updated to.
This method can filter the collection of collision candidates by removing
potential collisions. For the specified operation to succeed, the
collection of collision candidates must be empty when this method returns.
