Example 2 with Composite

use of me.prettyprint.hector.api.beans.Composite in project cassandra-tutorial by zznate.

the class CompositeQuery method main.

public static void main(String[] args) {
    init();
    CompositeQuery compositeQuery = new CompositeQuery();
    // Note the use of 'equal' and 'greater-than-equal' for the start and end.
    // this has to be the case when we want all 
    Composite start = compositeFrom(startArg, Composite.ComponentEquality.EQUAL);
    Composite end = compositeFrom(startArg, Composite.ComponentEquality.GREATER_THAN_EQUAL);
    compositeQuery.printColumnsFor(start, end);
}
