Constructor Detail

LongDataType

public LongDataType(String name,
                    boolean primitive)

Parameters:

primitive - indicate if a primitive type should be used

Method Detail

getMin

public long getMin()

Returns:

the minimum value as an long, or Long.MIN_VALUE if there is no minimum.

getMax

public long getMax()

Returns:

the maximum value as an long, or Long.MAX_VALUE if there is no maximum.

increase

public Long increase(Long 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<Long>

decrease

public Long decrease(Long 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<Long>

first

public Long first()

Description copied from class: ComparableDataType

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

Specified by:

first in interface SequentialDataType<Long>

Specified by:

first in class ComparableDataType<Long>
