Instance Method

blockTreeEntry(byHash:)

Looks up a block tree entry by its block hash.

func blockTreeEntry(byHash hash: BlockHash) -> BlockTreeEntry?

Parameters

hash: The block hash to look up.

Return Value

The matching BlockTreeEntry, or nil if the kernel has no record of a block with that hash.

Discussion

Searches the full block index — which includes blocks on side chains the kernel has evaluated but not adopted, not just the active chain. Cheap: backed by an in-memory hash table.
