add-to-chainclj
(add-to-chain chain
{:blueprint.interceptor/keys [position target] :as interceptor})Adds an interceptor to the chain, :blueprint.handler/position determines
the position in the chain, and can be:
:first: Puts the interceptor at the beginning of the chain.:last: Puts the interceptor at the end of the chain.:before: Puts the interceptor before the one whose name is stored at the:blueprint.interceptor/targetkey in the input map.:after: Puts the interceptor after the one whose name is stored at the:blueprint.interceptor/targetkey in the input map.
Incorrect parameters will yield to thrown exceptions.
Adds an interceptor to the chain, `:blueprint.handler/position` determines the position in the chain, and can be: - `:first`: Puts the interceptor at the beginning of the chain. - `:last`: Puts the interceptor at the end of the chain. - `:before`: Puts the interceptor before the one whose name is stored at the `:blueprint.interceptor/target` key in the input map. - `:after`: Puts the interceptor after the one whose name is stored at the `:blueprint.interceptor/target` key in the input map. Incorrect parameters will yield to thrown exceptions.

(build-chain default-interceptors
{:blueprint.interceptor/keys [additional disabled] :as config})Build an interceptor chain in three phases:
- Start from the default chain
- Process additional interceptors provided in
::additional - Removes interceptors by name based on those provided in
::disabled - Call the interceptor build step if any with the provided config

build-withclj
(build-with config {:keys [builder spec] :as interceptor})Interceptor builder, if a :builder key is found in the
interceptor, it will be called on itself, with the configuration
as a second argument. Validates with spec at :spec key if provided.
This allows providing configuration to the chain

expand-chainclj
(expand-chain ixdef)Resolve element to an interceptor chain. Works against all
implementations of BlueprintInterceptorChain, maps containing
::interceptor-chain, vectors are rendered as is, and single
interceptors are rendered as a vector of themselves.
