Overview

Package metadata provides functions and SQL fragments for working with the "factom_chain" and "fat_chain" metadata tables, which store the sync height, sync DBKeyMR, factom.NetworkID, and factom.Identity.

Constants

const CreateTableFATChain = `` /* 398-byte string literal not displayed */

CreateTableFATChain is a SQL string that creates the "fat_chain" metadata table.

The "fat_chain" table has a foreign key reference to the "entry" table, which must exist first.

const CreateTableFactomChain = `` /* 269-byte string literal not displayed */

CreateTableFactomChain is a SQL string that creates the "factom_chain" metadata table.

Functions

func AddNumIssued

func AddNumIssued(conn *sqlite.Conn, add uint64) error

func InsertFATChain

func InsertFATChain(conn *sqlite.Conn, tokenID string, issuer *factom.Bytes32) error

Insert the TokenID and issuer Chain ID into the first row of the "fat_chain" table. This may only ever be called once for a given database.

func InsertFactomChain

func InsertFactomChain(conn *sqlite.Conn,
	networkID factom.NetworkID,
	chainID *factom.Bytes32) error

Insert the syncHeight, syncDBKeyMR, and networkID into the first row of the "factom_chain" table. This may only ever be called once for a given database.

func SelectFATChain

func SelectFATChain(conn *sqlite.Conn) (numIssued uint64,
	tokenID string,
	identity factom.Identity,
	issuance fat.Issuance,
	err error)

func SelectFactomChain

func SelectFactomChain(conn *sqlite.Conn) (syncHeight uint32,
	syncDBKeyMR factom.Bytes32,
	networkID factom.NetworkID,
	err error)

func SetInitEntryID

func SetInitEntryID(conn *sqlite.Conn, id int64) error

SetInitEntryID updates the "init_entry_id"

func SetSync

func SetSync(conn *sqlite.Conn, height uint32, dbKeyMR *factom.Bytes32) error

SetSync updates the "sync_height" and "sync_db_key_mr".

func UpdateIdentity

func UpdateIdentity(conn *sqlite.Conn, identity factom.Identity) error
