Method Detail

name

java.lang.String name()

Get the name of the variable to which settings apply.

Returns:

The name.

stepSize

double stepSize()

The step size for this variable.

Returns:

the step size.

upperBound

double upperBound()

Get the upper bound.

Returns:

The upper bound.

lowerBound

double lowerBound()

Get the lower bound.

Returns:

The lower bound.

isBound

boolean isBound()

Check if a variable is bounded. A variable is bounded if either the upper bound or the lower bound are not infinity.

Returns:

true if the variable is bounded.

isFixed

boolean isFixed()

Check if a variable is fixed.

Returns:

true if the variable is fixed.

setStepSize

void setStepSize(double step)
          throws java.lang.IllegalArgumentException

Set the step size for this variable.

Parameters:

step - The step size.

Throws:

java.lang.IllegalArgumentException - if the step is not positive.

setBounds

void setBounds(double lowerBound,
               double upperBound)
        throws java.lang.IllegalArgumentException

Set the bounds for the variable.

Parameters:

lowerBound - The lower bound.

upperBound - The upper bound.

Throws:

java.lang.IllegalArgumentException - if the lowerBound is not lower than the upperBound.

removeBounds

void removeBounds()

Reset the bounds.

setFixed

void setFixed(boolean isFixed)

Set the fixed/unfixed status of a variable.

Parameters:

isFixed - The fixed status of a variable.

reset

void reset()

Reset the IVariableSetting ot its defaults.

setValue

void setValue(double value)

Set the current value of this variable.

Parameters:

value - The current value.

value

double value()

The current value for this variable.

Returns:

The current value.
