Functions ¶
func ConstructQueryResponse ¶
func ConstructQueryResponse(resultsIterator shim.StateQueryIteratorInterface, collection string, isCompositeKey bool, stub shim.ChaincodeStubInterface) ([]byte, error)
ConstructQueryResponse iterate through query result to create array of key-value pairs, i.e. JSON string of format [{"key":"mykey", "value":{}}, ...]
func ExtractCompositeKeys ¶
func ExtractCompositeKeys(stub shim.ChaincodeStubInterface, compositeKeyDefs string, keyValue string, value interface{}) []string
ExtractCompositeKeys collects all valid composite-keys matching composite-key definitions using fields of a value object
func GetActivityInputSchema ¶
GetActivityInputSchema returns schema of an activity input attribute
func GetActivityOutputSchema ¶
GetActivityOutputSchema returns schema of an activity output attribute
func GetChaincodeStub ¶
func GetChaincodeStub(ctx activity.Context) (shim.ChaincodeStubInterface, error)
GetChaincodeStub returns Fabric chaincode stub from the activity context
func ParseCompositeKeyDefs ¶ added in v1.0.0
ParseCompositeKeyDefs parses composite-key definition of format 'key1=field1,field2;key2=field3,field4'
func ResolveFlowData ¶
ResolveFlowData resolves and returns data from the flow's context, unmarshals JSON string to map[string]interface{}. The name to Resolve is a valid output attribute of a flogo activity, e.g., `activity[app_16].value` or `$.content`, which is shown in normal flogo mapper as, e.g., "$.content"
func SetChaincodeLogLevel ¶
func SetChaincodeLogLevel(logger *shim.ChaincodeLogger)
SetChaincodeLogLevel sets log level of a chaincode logger according to env 'CORE_CHAINCODE_LOGGING_LEVEL'
Types ¶
type ParameterIndex ¶
type ParameterIndex struct {
Name string
JSONType string
// contains filtered or unexported fields
}
ParameterIndex stores transaction parameters and its location in raw JSON schema string start and end location is used to sort the parameter list to match the parameter order in schema
func OrderedParameters ¶
func OrderedParameters(schemaData []byte) ([]ParameterIndex, error)
OrderedParameters returns parameters of a JSON schema object sorted by their position in schema definition This is necessary because Golang JSON parser does not maintain the sequence of object parameters.
