Overview

Package views provides high-level clients for talking to the main data tree in certain context.

It follows the "wrapper" pattern of http handlers to filter all requests inputs and outputs. The "Router" is object is used by all services or gateways when accessing to data as a given user. Between others, it will - Load ACLs and perform checks to make sure user is allowed to read/write the data - Perform other meta-related or acl-related checks like Quota management, locks, etc.. - Perform encryption/decryption of actual data on the fly - Compress / Decompress archives, - Add metadata collected from any services on the nodes outputted by the responses, - etc...

Functions

func AccessListFromContext 

func AccessListFromContext(ctx context.Context) (*permissions.AccessList, error)

func AncestorsListFromContext 

func AncestorsListFromContext(ctx context.Context, node *tree.Node, identifier string, p *ClientsPool, orParents bool) (updatedContext context.Context, parentsList []*tree.Node, e error)
