Types

type KVData

type KVData struct {
	Collection string `json:"collection"` // optional
	Key        string `json:"key"`        // required
	Value      string `json:"value"`      // required for read, ignored for write
}

KVData contains the data to read/write a key. Key is required. Value is required for write and ignored for read. When Collection is empty string "", it will read/write state data. When Collection is not empty string "", it will read/write private data in the collection.

type KVExcutor

type KVExcutor struct {
}

KVExcutor is a chaincode implementation that takes a KVData array as read parameter and a a KVData array as write parameter, and then calls GetXXX/PutXXX methods to read and write state/collection data. Both input params should be marshalled json data and then base64 encoded.
