Keith Turner commented on ACCUMULO-1000:
----------------------------------------
Maybe something like the following is an option.
{code:java}
public class Column {
public Column(byte[] colf, byte colq[]){}
//setters for optional parts
public Column setColVis(ColVis cv){}
public Column setTimestamp(long ts){}
}
public abstract class Test {
//package private constructor to limit subtypes
Test(){}
}
public class AbsenceTest extends Test {
public AbsenceTest();
}
public class EqualityTest extend Test {
public EqualityTest(byte[] val);
}
public class ConditionalMutation extends Mutation {
public void putCondition(Column col, Test test);
}
{code:java}
> support compare and set
