is supposed to enable enumerating records in the database but when we tried it, it did not work. e.g.:
public async getAssets(ctx:
Context): Promise<Asset[]> {
const assets:
Asset[] = [];
const results =
await ctx.stub.getStateByRange('',
'');
while (true) {
let item =
await results.next();
if (item.done) {
break;
} else {
let buffer =
item.value.getValue();
let asset =
JSON.parse(buffer.buffer.toString())
as Asset; // buffer.buffer returns many records not just once and the JSON.parse will fail
assets.push(asset);
}
}
await results.close();
return assets;
}
buffer.toString()
"ByteBufferNB(offset=22,markedOffset=-1,limit=386,capacity=1981)"
buffer.buffer.toString()
"
