Overview

Package shim provides APIs for the chaincode to access its state variables, transaction context and call other chaincodes.

Interfaces to allow testing of chaincode apps with mocked up stubs

Package shim provides APIs for the chaincode to access its state variables, transaction context and call other chaincodes.

Package shim is a generated protocol buffer package.

It is generated from these files: 

table.proto

It has these top-level messages:

Types

type Chaincode 

type Chaincode interface {
	// Init is called during Deploy transaction after the container has been
	// established, allowing the chaincode to initialize its internal data
	Init(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)

	// Invoke is called for every Invoke transactions. The chaincode may change
	// its state variables
	Invoke(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)

	// Query is called for Query transactions. The chaincode may only read
	// (but not modify) its state variables and return the result
	Query(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)
}

Chaincode interface must be implemented by all chaincodes. The fabric runs the transactions by calling these functions as specified.

type ChaincodeLogger 

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

ChaincodeLogger is an abstraction of a logging object for use by chaincodes. These objects are created by the NewLogger API.

func NewLogger 

func NewLogger(name string) *ChaincodeLogger

NewLogger allows a Go language chaincode to create one or more logging objects whose logs will be formatted consistently with, and temporally interleaved with the logs created by the shim interface. The logs created by this object can be distinguished from shim logs by the name provided, which will appear in the logs.

func (*ChaincodeLogger) Critical 

func (c *ChaincodeLogger) Critical(args ...interface{})

func (c *ChaincodeLogger) Debug(args ...interface{})

Debug logs will only appear if the ChaincodeLogger LoggingLevel is set to LogDebug.

func (*ChaincodeLogger) Debugf 

func (c *ChaincodeLogger) Debugf(format string, args ...interface{})

Debugf logs will only appear if the ChaincodeLogger LoggingLevel is set to LogDebug.

Errorf logs will appear if the ChaincodeLogger LoggingLevel is set to LogError, LogWarning, LogNotice, LogInfo or LogDebug.

func (*ChaincodeLogger) Info 

func (c *ChaincodeLogger) Info(args ...interface{})

Info logs will appear if the ChaincodeLogger LoggingLevel is set to LogInfo or LogDebug.

func (*ChaincodeLogger) Infof 

func (c *ChaincodeLogger) Infof(format string, args ...interface{})

Infof logs will appear if the ChaincodeLogger LoggingLevel is set to LogInfo or LogDebug.

func (*ChaincodeLogger) IsEnabledFor 

func (c *ChaincodeLogger) IsEnabledFor(level LoggingLevel) bool

IsEnabledFor returns true if the logger is enabled to creates logs at the given logging level.

func (*ChaincodeLogger) Notice 

func (c *ChaincodeLogger) Notice(args ...interface{})

Notice logs will appear if the ChaincodeLogger LoggingLevel is set to LogNotice, LogInfo or LogDebug.

func (*ChaincodeLogger) Noticef 

func (c *ChaincodeLogger) Noticef(format string, args ...interface{})

func (*ChaincodeLogger) SetLevel 

func (c *ChaincodeLogger) SetLevel(level LoggingLevel)
