Documentation

Overview

Package input defines consumers for aggregating data from a variety of sources. All consumer types must implement interface input.Type.

If the source of an input consumer supports acknowledgements then the implementation of the input will wait for each message to reach a permanent destination before acknowledging it.

Functions

func Descriptions 

func Descriptions() string

Descriptions returns a formatted string of descriptions for each type.

func DocumentPlugin 

func DocumentPlugin(
	typeString, description string,
	configSanitiser PluginConfigSanitiser,
)

DocumentPlugin adds a description and an optional configuration sanitiser function to the definition of a registered plugin. This improves the documentation generated by PluginDescriptions.

func PluginCount 

func PluginCount() int

func PluginDescriptions 

func PluginDescriptions() string

RegisterPlugin registers a plugin by a unique name so that it can be constructed similar to regular inputs. If configuration is not needed for this plugin then configConstructor can be nil. A constructor for the plugin itself must be provided.

func SanitiseConfig 

func SanitiseConfig(conf Config) (interface{}, error)

type TypeSpec 

type TypeSpec struct {
	// contains filtered or unexported fields
}

TypeSpec is a struct containing constructors, markdown descriptions and an optional sanitisation function for each input type.

type UDPServer 

type UDPServer struct {
	// contains filtered or unexported fields
}

func (t *UDPServer) Connected() bool

Connected returns a boolean indicating whether this input is currently connected to its target.

func (*UDPServer) TransactionChan 

func (t *UDPServer) TransactionChan() <-chan types.Transaction

TransactionChan returns a transactions channel for consuming messages from this input.

func (*UDPServer) WaitForClose 

func (t *UDPServer) WaitForClose(timeout time.Duration) error

type WithPipeline 

type WithPipeline struct {
	// contains filtered or unexported fields
}

WithPipeline is a type that wraps both an input type and a pipeline type by routing the input through the pipeline, and implements the input.Type interface in order to act like an ordinary input.

func WrapWithPipeline 

func WrapWithPipeline(procs *int, in Type, pipeConstructor types.PipelineConstructorFunc) (*WithPipeline, error)

WrapWithPipeline routes an input directly into a processing pipeline and returns a type that manages both and acts like an ordinary input.

func (*WithPipeline) CloseAsync
