Package org.activemath.util.checks Description

This package contains all classes needed to check ActiveMath's condition at runtime.

Current checks implemented:

• (UsermodelChecker) to check whether the Usermodel is running
• MapleChecker to check whether Maple is reachable, running and able to do a simple calculation
• FileMBaseChecker to check whether the FileMBase is reachable
\
• DummyChecker, which simulates failing checks and blocking threads, which is useful for development

Several checkers may be collected in a CheckerContainer which itself is used in the following checker meta-modules:

• CheckerServlet, which accumulates several checks and displays them via http requests
• MailingChecker, which accumulates several checks and sends its conditions via SMTP
