compute-for clj macro

(compute-for bindings & body)

eager-for clj macro

(eager-for & body)

A for wrapped with a doall to force realisation. Usage is the same as regular for.

group-by-seq clj

(group-by-seq f coll)

Groups the items of the given coll by f to each item. Returns a seq of tuples of the form [f-val xs] where xs are items from the coll and f-val is the result of applying f to any of those xs. Each x in xs has the same value (f x). xs will be in the same order as they were found in coll. The behavior is similar to calling (seq (group-by f coll)) However, the returned seq will always have consistent ordering from process to process. The ordering is insertion order as new (f x) values are found traversing the given coll collection in its seq order. The returned order is made consistent to ensure that relevant places within the rules engine that use this grouping logic have deterministic behavior across different processes.

jeq-wrap clj

(jeq-wrap value)

wraps the value with a JavaEqualityWrapper

query-param clj

(query-param p)

Coerces a query param to a parameter keyword such as :?param, if an unsupported type is supplied then an exception will be thrown

throw-error clj

(throw-error description)

Throw an error with the given description string.

with-thread-local-binding clj macro

(with-thread-local-binding bindings & body)

Wraps given body in a try block, where it sets each given ThreadLocal binding and removes it in finally block.
