@brief Checks if the query has further results.
graph_query.hasNext()
The generated statement maintains a cursor for you. If this cursor is already present hasNext() will use this cursors position to determine if there are further results available. If the query has not yet been executed hasNext() will execute it and create the cursor for you.
@EXAMPLES
Start query execution with hasNext:
@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLHasNext} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._vertices(); query.hasNext(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
Iterate over the result as long as it has more elements:
@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLHasNextIteration} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._vertices(); | while (query.hasNext()) { | var entry = query.next(); | // Do something with the entry } ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
