Constructor Detail

SimpleNumberInputConstraint

public SimpleNumberInputConstraint()

Constructs a constraint.

SimpleNumberInputConstraint

public SimpleNumberInputConstraint(int flags)

Constructs a constraint.

Parameters:

flags - a combination of SimpleConstraint.NO_POSITIVE, SimpleConstraint.NO_NEGATIVE, SimpleConstraint.NO_ZERO, and so on.

SimpleNumberInputConstraint

public SimpleNumberInputConstraint(java.lang.String constraint)

Constructs a constraint with a list of constraints separated by comma.

Parameters:

constraint - a list of constraints separated by comma. Example: no positive, no zero

Method Detail

getMin

public T getMin()

Returns the minimum value.

setMin

public void setMin(T min)

Sets the minimum value.

getMax

public T getMax()

Returns the maximum value.

setMax

public void setMax(T max)

Sets the maximum value.

parseValue

protected abstract T parseValue(java.lang.String value)

Parse the string value to the specified number type T. This method should be implemented by subclasses to convert a string representation of a number to the appropriate numeric type for this constraint.

Parameters:

value - the string representation of a number

Returns:

the parsed number of type T

parseConstraint

protected int parseConstraint(java.lang.String constraint)
                       throws org.zkoss.zk.ui.UiException

Description copied from class: SimpleConstraint

Parses a constraint into an integer value. For example, "no positive" is parsed to SimpleConstraint.NO_POSITIVE.

Deriving classes might override this to provide more constraints.

Overrides:

parseConstraint in class SimpleConstraint

Throws:

org.zkoss.zk.ui.UiException

validate

public void validate(org.zkoss.zk.ui.Component comp,
                     java.lang.Object value)
              throws org.zkoss.zk.ui.WrongValueException

Description copied from interface: Constraint

Verifies whether the value is acceptable.

Specified by:

validate in interface Constraint

Overrides:

validate in class SimpleConstraint

Parameters:

comp - the component being validated

Throws:

org.zkoss.zk.ui.WrongValueException

outOfRangeValue

protected org.zkoss.zk.ui.WrongValueException outOfRangeValue(org.zkoss.zk.ui.Component comp)
