Methods

Copy(IStore, IStore)

Makes a store, to, logically (but not necessarily physically) identical to another store, from. As this copies the contents of the store, instead of its physicall data, this can be used for migrating between two different types of IStore implementations.

Declaration

public static void Copy(this IStore from, IStore to)

Parameters

Type	Name	Description
IStore	from	The store containing the source contents.
IStore	to	The store to contain the copied contents. Expected to be empty.

Exceptions

Type	Condition
ArgumentException	Thrown when the store passed through to is not empty.

GetStateRootHash(IStore, Nullable<BlockHash>)

Gets the StateRootHash of the given blockHash.

Declaration

public static HashDigest<SHA256>? GetStateRootHash(this IStore store, BlockHash? blockHash)

Parameters

Type	Name	Description
IStore	store	The store that blocks are stored.
Nullable<BlockHash>	blockHash	The hash of the block to get the state root hash of. This can be null.

Returns

Type	Description
Nullable<HashDigest<SHA256>>	The state root hash of the block associated with blockHash if found or null if blockHash is itself null.

Exceptions

Type	Condition
ArgumentException	Thrown when blockHash is not null but the corresponding block is not found in store.
