tech.v3.resource.stack — techascent/tech.resource 5.09

Implementation of stack based resource system. Simple, predictable, deterministic, and applicable to most problems. Resource contexts are sequences of resources that need to be, at some point, released.

*bound-resource-context?* clj

*resource-context* clj

*resource-debug-double-free* clj

do-release clj

(do-release item)

ignore clj

(ignore item)

Ignore specifically this resource.

ignore-resources clj

(ignore-resources pred)

Ignore these resources for which pred returns true and do not track them. They will not be released unless added again with track

release clj

(release item)

Release this resource and remove it from tracking. Exceptions propagate to callers.

release-current-resources clj

(release-current-resources)

(release-current-resources pred)

Release all resources matching either a predicate or all resources currently tracked. Returns any exceptions that happened during release but continues to attempt to release anything else in the resource list.

release-resource-seq clj

(release-resource-seq res-ctx & {:keys [pred]})

Release a resource context returned from return-resource-context.

return-resource-seq clj macro

(return-resource-seq & body)

Run code and return both the return value and the resources the code created. Returns: {:return-value retval :resource-seq resources}

track clj

(track item)

(track item dispose-fn)

Begin tracking this resource. Resource be released when current resource context ends. If the item satisfies the PResource protocol, then it can be tracked itself. Else the dispose function is tracked.

with-bound-resource-seq clj macro

(with-bound-resource-seq resource-seq & body)

Run code and return both the return value and the (updated,appended) resources created. Returns: {:return-value retval :resource-seq resources}

with-resource-context clj macro

(with-resource-context & body)

Begin a new resource context. Any resources added while this context is open will be released when the context ends.
