Detailed Description

Encapsulation of a block header. Class to contain all of a block header's data. It is able to parse a block header and populate from some given RLP block serialisation with the static fromHeader(), through the method populate(). This will not conduct any verification above basic formating. In this case extra verification can be performed through verify().

The object may also be populated from an entire block through the explicit constructor BlockHeader(bytesConstRef) and manually with the populate() method. These will conduct verification of the header against the other information in the block.

The object may be populated with a template given a parent BlockHeader object with the populateFromParent() method. The genesis block info may be retrieved with genesis() and the corresponding RLP block created with createGenesisBlock().

To determine the header hash without the nonce (for sealing), the method hash(WithoutNonce) is provided.

The default constructor creates an empty object, which can be tested against with the boolean conversion operator.
