示例1: getDataFrameOfElementsWithEntityGroup
import org.apache.spark.sql.Dataset; //導入方法依賴的package包/類
public void getDataFrameOfElementsWithEntityGroup() {
// ---------------------------------------------------------
final GetDataFrameOfElements operation = new GetDataFrameOfElements.Builder()
.view(new View.Builder()
.entity("entity")
.build())
.build();
// ---------------------------------------------------------
final Dataset<Row> df = runExample(operation, null);
// Restrict to entities involving certain vertices
final Dataset<Row> seeded = df.filter("vertex = 1 OR vertex = 2");
String result = seeded.showString(100, 20);
printJava("df.filter(\"vertex = 1 OR vertex = 2\").show();");
print("The results are:\n");
print("```");
print(result.substring(0, result.length() - 2));
print("```");
// Filter by property
final Dataset<Row> filtered = df.filter("count > 1");
result = filtered.showString(100, 20);
printJava("df.filter(\"count > 1\").show();");
print("The results are:\n");
print("```");
