MongoDB\Driver\Exception\RuntimeException::hasErrorLabel — Returns whether an error label is associated with an exception

说明

final public MongoDB\Driver\Exception\RuntimeException::hasErrorLabel ( string $errorLabel ) : bool

Returns whether the errorLabel has been set for this exception. Error labels are set by either the server or the driver to indicated specific situations on which you might want to decide on how you want to handle a specific exception. A common situation might be to find out whether you can safely retry a transaction that failed due to a transient error (like a networking issue, or a transaction conflict). Examples of error labels are TransientTransactionError and UnknownTransactionCommitResult.

参数

errorLabel: The name of the errorLabel to test for.

返回值

Whether the given errorLabel is associated with this exception.
