Instance Method

entry(atHeight:)

Retrieves a block tree entry by its height on the active chain.

func entry(atHeight height: Int32) -> BlockTreeEntry?

Parameters

height: The block height (0 for genesis).

Return Value

The active-chain entry at that height, or nil if out of range.

Discussion

Returns nil for heights greater than height or negative heights. Note that this is height-on-the-active-chain lookup; use blockTreeEntry(byHash:) to access blocks on side chains.
