timerfindall — Find all timer objects by exact property value.
timerfindall returns valid timer handles regardless of ObjectVisibility, optionally filtered by exact property values.
Syntax
timers = timerfindall
timers = timerfindall(Name, Value, ...)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
Name,Value | Any | Variadic | — | Property filters matched by exact value. |
Returns
| Name | Type | Description |
|---|---|---|
timers | Any | Matching timer handle, empty cell row, or cell row of timer handles. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:timer:InvalidInput | A timer argument, property, or callback value has an unsupported type. | timer: invalid input |
RunMat:timer:InvalidProperty | A timer property name is unknown, read-only, or has an invalid value. | timer: invalid property |
RunMat:timer:InvalidHandle | A lifecycle method receives a non-timer or invalid timer handle. | timer: invalid timer handle |
RunMat:timer:CallbackFailed | A timer callback fails. | timer: callback failed |
RunMat:timer:GcFailure | A timer object cannot be allocated, rooted, read, or mutated. | timer: object storage failed |
How timerfindall works
timerfindallreturns visible and invisible valid timers in the current runtime thread.timerfindall(Name, Value, ...)applies exact property matches, including exact native integer comparisons.- A single match returns a scalar timer handle. Zero or multiple matches return a 1-by-N cell row.
- Deleted timers are removed from discovery.
Does RunMat run timerfindall on the GPU?
timerfindall is host-side handle registry lookup and has no GPU behavior.
Example
Find invisible timers
t = timer('ObjectVisibility', 'off', 'TimerFcn', @tick);
allTimers = timerfindallUsing timerfindall with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how timerfindall changes the result.
Run a small timerfindall example, explain the result, then change one input and compare the output.
FAQ
Which search forms are available?⌄
No-argument and name-value searches are available. Searching within a supplied timer array and filtering from a property structure are not yet implemented.
