Syntax

public class BlockChainStates : IBlockChainStates

Constructors

BlockChainStates(IStore, IStateStore)

A default implementation of IBlockChainStates interface.

Declaration

public BlockChainStates(IStore store, IStateStore stateStore)

Parameters

Type	Name	Description
IStore	store
IStateStore	stateStore

Methods

GetBalance(Address, Currency, BlockHash)

Queries address's balance of the currency in the BlockChain<T> from offset.

Declaration

public FungibleAssetValue GetBalance(Address address, Currency currency, BlockHash offset)

Parameters

Type	Name	Description
Address	address	The owner Address to query.
Currency	currency	The currency type to query.
BlockHash	offset	The HashDigest<T> of the block to start finding the state.

Returns

Type	Description
FungibleAssetValue	The address's current balance (or balance as of the given offset) of the currency.

GetStates(IReadOnlyList<Address>, BlockHash)

Gets multiple states associated to the specified addresses.

Declaration

public IReadOnlyList<IValue> GetStates(IReadOnlyList<Address> addresses, BlockHash offset)

Parameters

Type	Name	Description
IReadOnlyList<Address>	addresses	Addresses of states to query.
BlockHash	offset	The HashDigest<T> of the block to start finding the states.

Returns

Type	Description
IReadOnlyList<Bencodex.Types.IValue>	The states associated to the specified addresses. Associated values are ordered in the same way to the corresponding addresses. Absent states are represented as null.

GetTotalSupply(Currency, BlockHash)

Gets the total supply of a currency in the BlockChain<T> from offset, and if not found, return 0.

Declaration

public FungibleAssetValue GetTotalSupply(Currency currency, BlockHash offset)

Parameters

Type	Name	Description
Currency	currency	The currency type to query.
BlockHash	offset	The HashDigest<T> of the block to start finding the state.

Returns

Type	Description
FungibleAssetValue	The total supply value of currency at offset in FungibleAssetValue.

GetTrie(BlockHash)

Returns the state trie for offset.

Declaration

public ITrie GetTrie(BlockHash offset)

Parameters

Type	Name	Description
BlockHash	offset	The HashDigest<T> of the block to start finding the state.

Returns

Type	Description
ITrie	The merkle trie instance for given offset.

GetValidatorSet(BlockHash)

Returns the validator set in the BlockChain<T> from offset.

Declaration

public ValidatorSet GetValidatorSet(BlockHash offset)

Parameters

Type	Name	Description
BlockHash	offset	The HashDigest<T> of the block to start finding the state.

Returns

Type	Description
ValidatorSet	The validator set of type ValidatorSet at the offset.
