public interface IResourceVariantComparator
An
IResourceVariantComparator is provided by a Subscriber
and used by a SyncInfo to calculate the sync
state of the workspace resources. Subscribers should provide a criteria
best suited for their environment. For example, an FTP subscriber could choose to use file
size or file timestamps as comparison criteria whereas a CVS workspace subscriber would
use file revision numbers.- Since:

compare
Returnstrueif the local resource matches the remote resource based on this criteria andfalseotherwise. Comparing should be fast and based on cached information.- Parameters:
local- the local resource to be comparedremote- the remote resources to be compared- Returns:
trueif local and remote are equal based on this criteria andfalseotherwise.

base- the base resource to be comparedremote- the remote resources to be compared- Returns:
trueif base and remote are equal based on this criteria andfalseotherwise.

isThreeWay
boolean isThreeWay()Answerstrueif the base tree is maintained by this comparator's subscriber. If the base tree is not considered than the subscriber can be considered as not supported three-way comparisons. Instead comparisons are made between the local and remote only without consideration for the base.- Returns:
- whether this comparator is three-way or two-way
