Types ¶
type Credential ¶
The Credential is used to identify token owners.
type HistoryIterator ¶
type HistoryIterator struct {
// contains filtered or unexported fields
}
HistoryIterator is an iterator for iterating through the transaction history.
func (*HistoryIterator) Next ¶
func (it *HistoryIterator) Next() (string, *token.TokenTransaction, error)
Next gets the next transaction from the history, or io.EOF if there are no more transactions.
type Issuer ¶
type Issuer struct{}
An Issuer that can import new tokens
func (*Issuer) RequestImport ¶
func (i *Issuer) RequestImport(tokensToIssue []*token.TokenToIssue) (*token.TokenTransaction, error)
RequestImport creates an import request with the token owners, types, and quantities specified in tokensToIssue.
type MemoryPool ¶
type MemoryPool struct {
// contains filtered or unexported fields
}
A MemoryPool is an in-memory ledger of transactions and unspent outputs. This implementation is only meant for testing.
func (*MemoryPool) CommitUpdate ¶
func (p *MemoryPool) CommitUpdate(transactionData []tms.TransactionData) error
CommitUpdate commits transaction data into the pool.
func (*MemoryPool) HistoryIterator ¶
func (p *MemoryPool) HistoryIterator() *HistoryIterator
HistoryIterator creates a new HistoryIterator for iterating through the transaction history.
func (*MemoryPool) Iterator ¶
func (p *MemoryPool) Iterator() *PoolIterator
Iterator returns an iterator of the unspent outputs based on a copy of the pool.
func (*MemoryPool) OutputByID ¶
func (p *MemoryPool) OutputByID(id string) (*token.PlainOutput, error)
OutputByID gets an output by its ID.
func (*MemoryPool) TxByID ¶
func (p *MemoryPool) TxByID(txID string) (*token.TokenTransaction, error)
TxByID gets a transaction by its transaction ID. If no transaction exists with the given ID, a TxNotFoundError is returned.
type OutputNotFoundError ¶
type OutputNotFoundError struct {
ID string
}
OutputNotFoundError is returned when an entry was not found in the pool.
func (*OutputNotFoundError) Error ¶
func (o *OutputNotFoundError) Error() string
type PolicyValidator ¶
type PolicyValidator interface {
// IsIssuer returns true if the creator can issue tokens of the given type, false if not
IsIssuer(creator Credential, tokenType string) error
}
A PolicyValidator interface, used by TMS components to validate fabric channel policies
type Pool ¶
type Pool interface {
CommitUpdate(transactionData []tms.TransactionData) error
}
A Pool implements a UTXO pool
type PoolIterator ¶
type PoolIterator struct {
// contains filtered or unexported fields
}
PoolIterator is an iterator for iterating through the items in the pool.
func (*PoolIterator) Next ¶
func (it *PoolIterator) Next() (string, *token.PlainOutput, error)
Next gets the next output from the pool, or io.EOF if there are no more outputs.
type TxNotFoundError ¶
type TxNotFoundError struct {
TxID string
}
TxNotFoundError is returned when a transaction was not found in the pool.
func (*TxNotFoundError) Error ¶
func (p *TxNotFoundError) Error() string
type Verifier ¶
type Verifier struct {
Pool Pool
PolicyValidator PolicyValidator
// contains filtered or unexported fields
}
A Verifier validates and commits token transactions.
func (*Verifier) Commit ¶
func (v *Verifier) Commit(creator Credential, transactionData []tms.TransactionData) error
Commit checks that transactions are correct wrt. the most recent ledger state. Commit checks shall be done in parallel, since transactions within a block may introduce dependencies.
func (*Verifier) Validate ¶
func (v *Verifier) Validate(creator Credential, data tms.TransactionData) error
Validate checks transactions to see if they are well-formed. Validation checks can be done in parallel for all of the token transactions within a block.
