Draft implementation for multipleOperations

[white-gecko]

In SPARQL 1.1 Update: 3 SPARQL 1.1 Update Language

A request is a sequence of operations and is terminated by EOF (End of File). Multiple operations are separated by a ';' (semicolon) character. A semicolon after the last operation in a request is optional. Implementations MUST ensure that the operations of a single request are executed in a fashion that guarantees the same effects as executing them sequentially in the order they appear in the request.

I did not yet fully understand the interface, so this is just a placeholder.

The idea is to simplify:

const updates = []

updates.push(sparql.deleteData(deleteArray).toString())
updates.push(sparql.insertData(insertArray).toString())

const updateString = updates.join(";")

or maybe even:

const updates = []

if (deleteArray && deleteArray.length > 0) {
  updates.push(sparql.deleteData(deleteArray).toString())
}
if (insertArray && insertArray.length > 0) {
  updates.push(sparql.insertData(insertArray).toString())
}

const updateString = updates.join(";")
