Constructor Detail

SwitchList

public SwitchList(int size)

Constructs an instance.

Parameters:

size - >= 0; the number of elements to be in the table

Method Detail

setImmutable

public void setImmutable()

Makes this instance immutable.

Overrides:

setImmutable in class MutabilityControl

size

public int size()

Gets the size of the list.

Returns:

>= 0; the list size

getValue

public int getValue(int n)

Gets the indicated test value.

Parameters:

n - >= 0;, < size(); which index

Returns:

the test value

getTarget

public int getTarget(int n)

Gets the indicated target. Asking for the target at size() returns the default target.

Parameters:

n - >= 0, <= size(); which index

Returns:

>= 0; the target

getDefaultTarget

public int getDefaultTarget()

Gets the default target. This is just a shorthand for getTarget(size()).

Returns:

>= 0; the default target

getTargets

public IntList getTargets()

Gets the list of all targets. This includes one extra element at the end of the list, which holds the default target.

Returns:

non-null; the target list

getValues

public IntList getValues()

Gets the list of all case values.

Returns:

non-null; the case value list

setDefaultTarget

public void setDefaultTarget(int target)

Sets the default target. It is only valid to call this method when all the non-default elements have been set.

Parameters:

target - >= 0; the absolute (not relative) default target address

add

public void add(int value,
                int target)

Adds the given item.

Parameters:

value - the test value

target - >= 0; the absolute (not relative) target address

removeSuperfluousDefaults

public void removeSuperfluousDefaults()

Shrinks this instance if possible, removing test elements that refer to the default target. This is only valid after the instance is fully populated, including the default target (naturally).
