BuildPamRequest takes a pointer to a http request and returns a PamRequest with policy values taken from the parameters of the passed request.

BuildPamResponse takes a pointer to a http response and returns a PamResponse with the ComputationLevel taken from the response header.

BuildRequestPolicy takes a http request and extracts the values for a RequestPolicy from its parameters.

ComputationLevelFromString converts a string to the relevant ComputationLevel.

MakePolicyAwareClient returns an PolicyAwareClient with initialised fields.

NewDynamicComputationPolicy returns a pointer to a DynamicComputationPolicy with an empty, initialised internal map.

NewStaticComputationPolicy returns a pointer to an initialised StaticComputationPolicy.

NewStaticDataPolicy returns a pointer to a StaticDataPolicy with initialised fields.

NewTableOperations returns a pointer to a TableOperations struct with initialised fields.

PolicyAwareHandler returns a http.Handler based on the passed ComputationPolicy.

ProcessingLocationFromString converts from a string to the relevant ProcessingLocation.

Specified if the request should ideally be executed locally and never leave the device.

Specified if the returned data would ideally be unprocessed.

DynamicComputationPolicy holds a set of computation capabilities for paths, these must be set manually.

MySQLPrivateDatabase is a wrapper around a MySQL database which implements the PrivateRelationalDatabase interface, it supports DataPolicies which specify transforms for columns and excluded columns on a per PrivacyGroup basis.

PamRequest contains a RequestPolicy and a http request.

PamResponse contains a http response and its associated computation level.

PolicyAwareClient wraps a http client with a ComputationPolicy.

PrivacyGroup a struct which contain a data structure of RequesterID's which we can Add to and Remove from.

RequestPolicy stores the preferred location for processing of a request (and the identity of the requester?).

StaticComputationPolicy holds a map from http request paths to computation capabilities which dictate which handlers can be used for the request.

StaticDataPolicy implements the DataPolicy interface and contains a list of privacyGroups and DataTransforms for them.

TableOperations contains functions to apply to tables before sending to an entity and columns to exclude.

ComputationPolicy stores the computation capabilities of a node.

DataPolicy allow us to get a function which must be applied to data before returning for a given identifier.

PrivateRelationalDatabase wraps an SQL database and edits queries so that they operate over tables adjusted to match privacy policies.

ComputationLevel specifies whether a handler for a http request can compute no globalResult, just provide the raw data or compute a full globalResult.

transforms is a map from privacyGroups to TableOperations.

ProcessingLocation refers to either local or remote computation over data.
