InMemoryBlobRepository class
In-memory implementation of IBlobRepository.
Stores blobs in memory using nested maps. Suitable for testing and development scenarios where persistence is not required.

Constructors
- InMemoryBlobRepository({int? maxBlobBytes, int readChunkBytes = _defaultReadChunkBytes, Clock? clock})
Properties
- hashCode → int

Methods
-
collectionSize(
String collection) → Future< int?> -
Total size in bytes of every blob in the collection, or null when this
backend cannot answer without walking the whole store.
override
-
deleteBlob(
String collection, String id, {int? expectedVersion}) → Future< bool> -
Delete a blob; returns
truewhen something was removed.override -
deleteCollection(
String collection) → Future< bool> -
Drop an entire collection (namespace) and all blobs within it.
override
-
deleteMany(
String collection, List< String> ids) → Future<Set< String> > -
Remove several blobs from one collection in as few round trips as the
backend allows.
override
-
dispose(
) → Future< void> -
override
-
ensureCollection(
String collection) → Future< void> -
Create the collection if it does not exist yet.
override
-
headBlob(
String collection, String id) → Future< BlobDescriptor?> -
Fetch blob metadata; return null when missing.
override
-
headMany(
String collection, List< String> ids) → Future<Map< String, BlobDescriptor> > -
Metadata for several blobs of one collection, keyed by id. Ids that are
not there are simply absent from the result.
override
-
listBlobs(
ListBlobsRequest request) → Future< ListBlobsResponse> -
List blob descriptors with pagination.
override
-
listCollections(
) → Future< List< String> > -
List known collections in the backing store.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readBlob(
BlobReadRequest request) → Future< BlobReadResult?> -
Stream blob bytes; return null when missing.
override
-
toString(
) → String -
A string representation of this object.
inherited
-
writeBlob(
BlobWriteRequest request) → Future< BlobWriteResult> -
Write blob from a byte stream; should enforce optimistic versioning when
expectedVersionis provided in the request.override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
