func SimpleWriterProvider ¶
func SimpleWriterProvider(w common.Writer) common.WriterProvider
SimpleWriterProvider returns WriterProvider that provides static context-independent Writer.
Types ¶
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
Controller represents main handler for starting and interrupting the reporting local trust values.
It binds the interfaces of the local value stores to the target storage points. Controller is abstracted from the internal storage device and the network location of the connecting components. At its core, it is a high-level start-stop trigger for reporting.
For correct operation, the controller must be created using the constructor (New) based on the required parameters and optional components. After successful creation, the constructor is immediately ready to work through API of external control of calculations and data transfer.
func New ¶
func New(prm Prm, opts ...Option) *Controller
New creates a new instance of the Controller.
Panics if at least one value of the parameters is invalid.
The created Controller does not require additional initialization and is completely ready for work.
func (*Controller) Report ¶
func (c *Controller) Report(prm ReportPrm)
Report reports local reputation values.
Single Report operation overtakes all data from LocalTrustSource to LocalTrustTarget (Controller's parameters).
Each call acquires a report context for an Epoch parameter. At the very end of the operation, the context is released.
func (*Controller) Stop ¶
func (c *Controller) Stop(prm StopPrm)
Stop interrupts the processing of local trust values.
Releases acquired report context.
type Iterator ¶
type Iterator interface { // Iterate must start an iterator over all trust values. // For each value should call a handler, the error // of which should be directly returned from the method. // // Internal failures of the iterator are also signaled via // an error. After a successful call to the last value // handler, nil should be returned. Iterate(reputation.TrustHandler) error }
Iterator is a group of methods provided by entity which can iterate over a group of reputation.Trust values.
type IteratorProvider ¶
type IteratorProvider interface { // InitIterator should return an initialized Iterator // that iterates over values from IteratorContext.Epoch() epoch. // // Initialization problems are reported via error. // If no error was returned, then the Iterator must not be nil. // // Implementations can have different logic for different // contexts, so specific ones may document their own behavior. InitIterator(common.Context) (Iterator, error) }
IteratorProvider is a group of methods provided by entity which generates iterators over reputation.Trust values.
func SimpleIteratorProvider ¶
func SimpleIteratorProvider(i Iterator) IteratorProvider
SimpleIteratorProvider returns IteratorProvider that provides static context-independent Iterator.
type Option ¶
type Option func(*options)
Option sets an optional parameter of Controller.
type Prm ¶
type Prm struct { // Iterator over the reputation values // collected by the node locally. // // Must not be nil. LocalTrustSource IteratorProvider // Place of recording the local values of // trust to other nodes. // // Must not be nil. LocalTrustTarget reputationcommon.WriterProvider }
Prm groups the required parameters of the Controller's constructor.
All values must comply with the requirements imposed on them. Passing incorrect parameter values will result in constructor failure (error or panic depending on the implementation).
type ReportPrm ¶
type ReportPrm struct {
// contains filtered or unexported fields
}
ReportPrm groups the required parameters of the Controller.Report method.
