Detailed Description

Holds a ledger.

The ledger is composed of two SHAMaps. The state map holds all of the ledger entries such as account roots and order books. The tx map holds all of the transactions and associated metadata that made it into that particular ledger. Most of the operations on a ledger are concerned with the state map.

This can hold just the header, a partial set of data, or the entire set of data. It all depends on what is in the corresponding SHAMap entry. Various functions are provided to populate or depopulate the caches that the object holds references to.

Ledgers are constructed as either mutable or immutable.

1) If you are the sole owner of a mutable ledger, you can do whatever you want with no need for locks.

2) If you have an immutable ledger, you cannot ever change it, so no need for locks.

3) Mutable ledgers cannot be shared.

Note: Presented to clients as ReadView; Calls virtuals in the constructor, so marked as final

ripple::Ledger::Ledger	(	create_genesis_t	,
		Config const &	config,
		std::vector< uint256 > const &	amendments,
		Family &	family
	)

Create the Genesis ledger.

The Genesis ledger contains a single account whose AccountID is generated with a Generator using the seed computed from the string "masterpassphrase" and ordinal zero.

The account has an XRP balance equal to the total amount of XRP in the system. No more XRP than the amount which starts in this account can ever exist, with amounts used to pay fees being destroyed.

Amendments specified are enabled in the genesis ledger
