Class Mutex
Mutual exclusion monitor.
Used to ensure mutual exclusion of calls to blocks.
Inheritance
This class must not be extended.
Class summary
| do [block] -> any | Calls the given block exclusively. |
|---|---|
| operator == other/any -> bool | Whether this object is equal to the other. |
| stringify -> string | Stringifies this object. |
| await [condition] -> none | Yields until the condition block returns true. |
| try-await --deadline/int [condition] -> any | Yields until the condition block returns true or until the given deadline is reached. |
Methods
Yields until the condition block returns true.
This should be called from a locked method.
The condition is not allowed to change the state, only query it.
Calls the given block exclusively.
Other calls to this method are blocked until this method has returned.
Whether this object is equal to the other.
Inheritance
Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:
class Pin:
number/int
constructor .number:
operator == other:
if other is not Pin: return false
return number == other.number
A class doesn't have to follow the above format, but it must keep the operator in sync with any
hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).Stringifies this object.
Inheritance
Objects that need a human-friendly string representation should overwrite this method. The default string is based on the internal class-ID.
Yields until the condition block returns true or until the given deadline is reached.
Returns true if the condition has been met or false if we have reached the deadline.
This should be called from a locked method.
The condition is not allowed to change the state, only query it.
