*exception-base-class*clj
Base exception class which will be caught by call. Dynamic, defaults to Throwable
Base exception class which will be caught by `call`. Dynamic, defaults to `Throwable`
*ignored-exceptions*clj
Exception classes which will be ignored by call. Dynamic, defaults to empty set
Exception classes which will be ignored by `call`. Dynamic, defaults to empty set
add-ignored-exceptions!clj
(add-ignored-exceptions! ex-class-set)Adds given set of classes to *ignored-exceptions*
Adds given set of classes to `*ignored-exceptions*`
callclj
(call f & args)Calls given function with supplied args in try/catch block. When caught an exception
which class is *exception-base-class* or a subclass of it, and is not listed in *ignored-exceptions*(and is not a subclass of any classes listed there)
returns instance of caught exception, otherwise throws it. If no exception has caught during function call returns its result
Calls given function with supplied args in `try/catch` block. When caught an exception which class is `*exception-base-class*` or a subclass of it, and is not listed in `*ignored-exceptions*`(and is not a subclass of any classes listed there) returns instance of caught exception, otherwise throws it. If no exception has caught during function call returns its result
catch-from!clj
(catch-from! ex-class)Sets exception-base-class to specified class
Sets *exception-base-class* to specified class
catchingcljmacro
(catching exception-base-class & body)Executes body with *exception-base-class* bound to given class
Executes body with `*exception-base-class*` bound to given class
elseclj
(else handler value)If value is a fail?, calls handler on it, otherwise returns value
If value is a `fail?`, calls handler on it, otherwise returns value
else-ifclj
(else-if ex-class handler value)If value is an exception of ex-class, applies handler to it, otherwise returns value
If value is an exception of ex-class, applies handler to it, otherwise returns value
failclj
(fail msg-or-data)(fail msg data)(fail msg data cause)Creates new ex-info instance with given msg, data(optional) and cause(optional)
Creates new `ex-info` instance with given msg, data(optional) and cause(optional)
fail?clj
(fail? value)(fail? ex-class value)Checks if value is exception of given class(optional, defaults to Throwable)
Checks if value is exception of given class(optional, defaults to Throwable)
fletcljmacro
(flet bindings & body)Flow adaptation of Clojure let. Wraps evaluation of each binding to call. If fail? value returned from binding evaluation, it's returned immediately and all other bindings and body are skipped
Flow adaptation of Clojure `let`. Wraps evaluation of each binding to `call`. If `fail?` value returned from binding evaluation, it's returned immediately and all other bindings and body are skipped
ignore-exceptions!clj
(ignore-exceptions! ex-class-set)Sets *ignored-exceptions* to given set
Sets `*ignored-exceptions*` to given set
ignored?clj
(ignored? ex-class)Checks if exception class should be ignored
Checks if exception class should be ignored
ignoringcljmacro
(ignoring ignored-exceptions & body)Executes body with *ignored-exceptions* bound to given value
Executes body with `*ignored-exceptions*` bound to given value
thenclj
(then handler value)If value is not a fail?, applies handler to it wrapped to call, otherwise returns value
If value is not a `fail?`, applies handler to it wrapped to `call`, otherwise returns value
thruclj
(thru handler value)Calls handler on value (for side effects). Returns value. Works similar to doto, but accepts function as first arg
