Interface THierarchicalChecksummable<TCollectionName>

An entity that can produce hierarchical content checksums: meta (entity-only), descendant (children), and combined (both).

interface THierarchicalChecksummable<TCollectionName extends string = string> {
    checksum(): string;
    combinedChecksum(): string;
    descendantChecksum(): string | null;
    flushChecksums(): void;
    getCollectionChecksum(name: TCollectionName): string | null;
}

Type Parameters

TCollectionName extends string = string

Methods

checksum

checksum(): string
Returns the meta checksum — derived from entity data only.

Returns string
- Defined in src/lib/core/interfaces/shared.interfaces.ts:21

combinedChecksum

combinedChecksum(): string
Returns the combined checksum — hash(checksum + descendantChecksum), or equals checksum if no descendants.

Returns string
- Defined in src/lib/core/interfaces/shared.interfaces.ts:25

descendantChecksum

descendantChecksum(): string | null
Returns the descendant checksum — derived from children's combinedChecksums. Null if no children.

Returns string | null
- Defined in src/lib/core/interfaces/shared.interfaces.ts:23

flushChecksums

flushChecksums(): void
Forces recomputation of all dirty checksums in the hierarchy.

Returns void
- Defined in src/lib/core/interfaces/shared.interfaces.ts:29

getCollectionChecksum

getCollectionChecksum(name: TCollectionName): string | null
Returns the checksum for a named descendant collection. Null if collection is empty.
Parameters
- name: TCollectionName
Returns string | null
- Defined in src/lib/core/interfaces/shared.interfaces.ts:27
