Method Detail

diverge

protected Column diverge(Class membType)
Description copied from class: Column
A shallow copy of the column. The members are shared, not copied. The new Column is restricted to only holding members of type membType.

Specified by:
diverge in class Column

get

Object get(int pos)
Specified by:
get in class Column

getInt

int getInt(int pos)

memberType

Class memberType()
Description copied from class: Column
All the members of the column must conform to this type

Specified by:
memberType in class Column

newVacant

Column newVacant(int capacity)
Description copied from class: Column
Makes a new column just like this one, except of the specified size and without any members.

Specified by:
newVacant in class Column

capacity

int capacity()
Specified by:
capacity in class Column

put

void put(int pos,
         Object value)
Specified by:
put in class Column

putInt

void putInt(int pos,
            int value)

vacate

void vacate(int pos)
Description copied from class: Column
Stop pointing at an object from this pos. If this is a scalar column, does nothing

Specified by:
vacate in class Column

clone

protected Object clone()
Argument defaults to memberType()

Overrides:
clone in class Object
Returns:
a clone of this instance.

values

public static Column values(int capacity)
memberType defaults to Object


values

public static Column values(Class memberType,
                            int capacity)
Make a value-column that can only hold values that conform to 'memberType' and has 'capacity' positions. If the memberType is a scalar type, the column will represent these values unboxed.
