Constructor Detail

IntegerDataType

public IntegerDataType(String name,
                       boolean primitive)

Parameters:

primitive - indicate if a primitive type should be used

Method Detail

inheritRestrictions

protected void inheritRestrictions(BasicDataType origin)

Description copied from class: BasicDataType

If a datatype inherits from another datatype all its restrictions inherit too.

Overrides:

inheritRestrictions in class ComparableDataType<Integer>

getMin

public int getMin()

Returns:

the minimum value as an int, or a very very small number if there is no minimum.

getMax

public int getMax()

Returns:

the maximum value as an int, or a very very big number if there is no maximum.

increase

public Integer increase(Integer pos)

Description copied from interface: SequentialDataType

Given a certain value, returns the value with is 1 bigger. It can return null if there is no such value (and the given value is the biggest one possible)

Specified by:

increase in interface SequentialDataType<Integer>

decrease

public Integer decrease(Integer pos)

Description copied from interface: SequentialDataType

Given a certain value, returns the value with is 1 smaller. It can return null if there is no such value (and the given value is the smallest one possible)

Specified by:

decrease in interface SequentialDataType<Integer>

first

public Integer first()

Description copied from class: ComparableDataType

Returns a natural 'first' value. This may return some kind of 0

Specified by:

first in interface SequentialDataType<Integer>

Specified by:

first in class ComparableDataType<Integer>
