Changeset 413 for trunk/EventBenchConsole/src/de/ugoe

Timestamp:

04/03/12 10:51:34 (13 years ago)

Author:

Message:

• changed equals method of de.ugoe.cs.eventbench.windows.data.WindowsEvent? to be able to better identify equal widgets throughout multiple sessions. To this aim, the class de.ugoe.cs.eventbench.windows.data.MFCTargetComparator has been introduced to compare the target strings of WindowsEvents?.
• changed parseXML to set up the MFCTargetComparator

Location:

trunk/EventBenchConsole/src/de/ugoe/cs/eventbench/windows

Files:

• commands/CMDparseXML.java (modified) (2 diffs)
• data/MFCTargetComparator.java (added)
• data/WindowsEvent.java (modified) (2 diffs)
