Extensions methods and helpers to work with Key Subspaces

Methods

ClearRange

static void ClearRange(IFdbTransaction trans, IKeySubspace subspace)

Clear the entire content of a subspace

ClearRangeAsync

static Task ClearRangeAsync(IFdbRetryable db, IKeySubspace subspace, CancellationToken ct)

Clear the entire content of a subspace

Contains

static bool Contains(IKeySubspace subspace, Slice absoluteKey)

Test if a key is inside the range of keys logically contained by this subspace

• subspace — Subspace used for the test
• absoluteKey — Key to test

Returns: True if the key can exist inside the current subspace.

Please note that this method does not test if the key actually exists in the database, only if the key is not outside the range of keys defined by the subspace.

Copy

static KeySubspace Copy(IKeySubspace subspace)

Create a copy of a generic subspace, sharing the same binary prefix
