AccessPolicies

The access policies of a node's aggregates (AccessPolicy, a bean of the service for each aggregate), each resolved to its aggregate and checked against the Manifest once, when the engine is built (of). An aggregate with a policy of its own is governed: its reads are what the policy's read lets a caller read (AccessQueryPolicy). Any other reads by the default rule, its caller's owner and space (ScopeQueryPolicy), as before access policies.

Functions

declares

fun declares(type: AggregateType, attribute: AccessAttribute<*, *>): Boolean

Whether attribute is one type has, as a policy of it may compare it: AccessAttribute.SPACE of every aggregate, AccessAttribute.OWNER of one its owner holds, and a declared one by its name, type and multiplicity.

governs

fun governs(type: AggregateType): Boolean

Whether type reads by a policy of its own rather than by the default rule.

fun governs(dataset: QueryDataset): Boolean

Whether dataset's rows are those of an aggregate that reads by a policy of its own, which its scope binds.

has

fun has(type: AggregateType): Boolean

Whether the node has type: one of the Manifest's aggregates.

fun of(type: AggregateType): AccessPolicy<*>?

The policy of type, or null when it reads by the default rule.

scopeOf

fun scopeOf(type: AggregateType, ownership: Ownership, scope: Scope): Scope

The owner and space of scope, a caller's, that every read of type holds the caller to (its snapshot and events queries, its state reads, in process and over HTTP): none where a policy of its own governs type, which decides them instead; otherwise the part of scope ownership, type's, keeps.
