| alert($message, $context) | aDeployTask | Action must be taken immediately. |
| backtraces($message, $context) | aDeployTask | Force-log a message at INFO level together with a full stack trace/memory snapshot (iLogLevel::BACKTRACE), bypassing the verbosity mask entirely (any non-zero verbosity is enough to trigger it). |
| critical($message, $context) | aDeployTask | Critical conditions. No-op if CRITICAL is currently filtered out by the verbosity mask. |
| debug($message, $context) | aDeployTask | Detailed debug information. |
| debugName() | aDeployTask | |
| emergency($message, $context) | aDeployTask | System is unusable. No-op if EMERGENCY is currently filtered out by the verbosity mask. |
| error($message, $context) | aDeployTask | Runtime errors that do not require immediate action but should typically be logged and monitored. |
| getDatabase($context) | aDatabaseTask | |
| getName() | aDeployTask | |
| getRepository($context) | aDatabaseTask | |
| getShell($context) | aDatabaseTask | |
| getVerbosity() | aDeployTask | |
| info($message, $context) | aDeployTask | Interesting events. No-op if INFO is currently filtered out by the verbosity mask. |
| isChange() | aDeployTask | Whether running this task CHANGES anything. |
| isNeeded($context) | aDeployTask | Whether this task has anything to do for this target -- e.g. |
| isRollbackCritical() | aDeployTask | |
| log($level, $message, $context) | aDeployTask | Logs with an arbitrary level. |
| notice($message, $context) | aDeployTask | Normal but significant events. |
| rollback($context) | aDeployTask | Undo this task. Called by the runner, in reverse order, for every task already applied when a later one failed. |
| setVerbosity($verb) | aDeployTask | Set the current verbosity mask, replacing whatever it was before. |
| snapshot($context) | aDatabaseTask | Take a snapshot of the target's database and record it on the context, so whatever comes next is reversible. |
| testVerbosity($level) | aDeployTask | Test whether a given level (or set of levels) is currently enabled by this instance's verbosity mask. |
| warning($message, $context) | aDeployTask | Exceptional occurrences that are not errors. |
