Constructor Detail

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(java.lang.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(java.lang.Integer minimum,
                             java.lang.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.

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.

Method Detail

isValidStep

protected boolean isValidStep(java.lang.Integer value,
                              java.lang.Integer step,
                              java.lang.Integer base)

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

Specified by:

isValidStep in class AbstractComparableRangeValidator<java.lang.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.
