Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`compareTo(T o)`	The default ordering is based on column value comparisons.
`boolean`	`equals(Object obj)`	The equals is based on equal column values.
`Comparable<?>[]`	`getColumns()`	Gets an array of all column values.
`int`	`hashCode()`	The hashCode is based on the column values.
`String`	`toString()`	Based on the column values (column1,column2,...)

- Method Detail
  - getColumns
```
Comparable<?>[] getColumns()
```
    Gets an array of all column values.
  - toString
```
String toString()
```
    Based on the column values (column1,column2,...)
    
    Overrides:
    
    toString in class Object
  - equals
```
boolean equals(Object obj)
```
    The equals is based on equal column values.
    
    Overrides:
    
    equals in class Object
  - hashCode
```
int hashCode()
```
    The hashCode is based on the column values.
    
    Overrides:
    
    hashCode in class Object
  - compareTo
```
int compareTo(T o)
```
    The default ordering is based on column value comparisons. If both values are Strings, will use the model comparator. If one tuple has few columns than the other, and all the values are equal, the tuple with fewer columns is considered to be first.
