Constructor Details

IntegerRangeValidator

public IntegerRangeValidator()

Default constructor with no value required and a step of one.

IntegerRangeValidator

public IntegerRangeValidator(boolean valueRequired)

Value required constructor with a step of one.

Parameters:

valueRequired - Whether the value must be non-null in order to be considered valid.

IntegerRangeValidator

public IntegerRangeValidator(Integer maximum)

Maximum constructor with a minimum value of zero and a step of one.

Parameters:

maximum - The maximum value, inclusive, or null if the range has no upper bound.

IntegerRangeValidator

public IntegerRangeValidator(Integer minimum,
 Integer maximum)

Minimum and maximum constructor with a step of one.

Parameters:

minimum - The minimum value, inclusive, or null if the range has no lower bound.

maximum - The maximum value, inclusive, or null if the range has no upper bound.

IntegerRangeValidator

public IntegerRangeValidator(Integer minimum,
 Integer maximum,
 Integer step)

Minimum, maximum, and step constructor.

Parameters:

minimum - The minimum value, inclusive, or null if the range has no lower bound.

maximum - The maximum value, inclusive, or null if the range has no upper bound.

step - The step amount, or null if the range has no increment value specified.

IntegerRangeValidator

public IntegerRangeValidator(Integer maximum,
 boolean valueRequired)

Minimum and value required constructor with a minimum value of zero and a step of one.

Parameters:

maximum - The maximum value, inclusive, or null if the range has no upper bound.

valueRequired - Whether the value must be non-null in order to be considered valid.

IntegerRangeValidator

public IntegerRangeValidator(Integer minimum,
 Integer maximum,
 boolean valueRequired)

Minimum, maximum, and value required constructor with a step of one.

Parameters:

minimum - The minimum value, inclusive, or null if the range has no lower bound.

maximum - The maximum value, inclusive, or null if the range has no upper bound.

valueRequired - Whether the value must be non-null in order to be considered valid.

IntegerRangeValidator

public IntegerRangeValidator(Integer minimum,
 Integer maximum,
 Integer step,
 boolean valueRequired)

Minimum, maximum, step, and value required constructor.

Parameters:

minimum - The minimum value, inclusive, or null if the range has no lower bound.

maximum - The maximum value, inclusive, or null if the range has no upper bound.

step - The step amount, or null if the range has no increment value specified.

valueRequired - Whether the value must be non-null in order to be considered valid.

Method Details

isValidStep

protected boolean isValidStep(Integer value,
 Integer step,
 Integer base)

Description copied from class: AbstractComparableRangeValidator

Determines whether the given value falls on the correct step amount relative to the base value.

Specified by:

isValidStep in class AbstractComparableRangeValidator<Integer>

Parameters:

value - The value to validate.

step - The step value.

base - The base (either the minimum or maximum value), or null if zero should be used as a base.

Returns:

true if the value is a valid step away from the given base.
