Method Detail

getNextValue

public java.lang.Object getNextValue()

Returns the next number in the sequence.

Specified by:

getNextValue in interface javax.swing.SpinnerModel

Returns:

value + stepSize or null if the sum exceeds maximum.

See Also:

SpinnerModel.getNextValue(), getPreviousValue(), SpinnerNumberModel.setStepSize(java.lang.Number)

getPreviousValue

public java.lang.Object getPreviousValue()

Returns the previous number in the sequence.

Specified by:

getPreviousValue in interface javax.swing.SpinnerModel

Returns:

value - stepSize, or null if the sum is less than minimum.

See Also:

SpinnerModel.getPreviousValue(), getNextValue(), SpinnerNumberModel.setStepSize(java.lang.Number)

getValue

public java.lang.Object getValue()

Returns the value of the current element of the sequence.

Specified by:

getValue in interface javax.swing.SpinnerModel

Returns:

the value property

See Also:

setValue(java.lang.Object), SpinnerNumberModel.getNumber()

setValue

public void setValue(java.lang.Object value)

Sets the current value for this sequence. No bounds checking is done here; the new value may invalidate the (minimum <= value <= maximum) invariant enforced by the constructors. It's also possible to set the value to be something that wouldn't naturally occur in the sequence, i.e. a value that's not modulo the stepSize. This is to simplify updating the model, and to accommodate spinners that don't want to restrict values that have been directly entered by the user. Naturally, one should ensure that the (minimum <= value <= maximum) invariant is true before calling the next, previous, or setValue methods.

This method fires a ChangeEvent if the value has changed.

Specified by:

setValue in interface javax.swing.SpinnerModel

Parameters:

value - the current (non null) Number for this sequence

Throws:

java.lang.IllegalArgumentException - if value is null or not a Number
