VALUE_VALID

Constructor Summary

LongVariable()

LongVariable(long v)

LongVariable(long v, long min, long max)

Method Summary

void	setValue(long value)
void	setValue(java.lang.Object value)
void	showAlertDialog(int cause, Unit unit) Provided so that derived classes can provide their own specic alert dialogs in case an attempt is made to set the variable to an unacceptable value.
int	validate(java.lang.Object value) Validates the value and returns a constant describing the result
boolean	valueEquals(java.lang.Object value) Note that, in the case that the value is an instance of class Float or class Double, this may return true, even if the numerical values are not equal but when cast to long will compare equal.

public LongVariable()

Method Detail

valueEquals

public boolean valueEquals(java.lang.Object value)

Note that, in the case that the value is an instance of class Float or class Double, this may return true, even if the numerical values are not equal but when cast to long will compare equal. This is because this uses ((Number)value).longValue() to obtain the value to compare with the variables value.

Overrides:

valueEquals in class Variable

Parameters:

value - the value to compare to the varible value.

Returns:

true if the values are equal

setValue

public void setValue(long value)

setValue

public void setValue(java.lang.Object value)

Specified by:

setValue in interface ValueInterface

Overrides:

setValue in class Variable

showAlertDialog

public void showAlertDialog(int cause,
                            Unit unit)

Description copied from class: Variable

Provided so that derived classes can provide their own specic alert dialogs in case an attempt is made to set the variable to an unacceptable value. s * @param cause an int value (defined by a derived class) that is the cause of the aler

Specified by:

showAlertDialog in interface ValueInterface

Overrides:

showAlertDialog in class Variable

unit - the unit in which to express the variable value or the value range.

validate

public int validate(java.lang.Object value)

Description copied from class: Variable

Validates the value and returns a constant describing the result

Specified by:

validate in interface ValueInterface

Overrides:

validate in class Variable

Parameters:

value - the value to validate

Returns:

by default returns ValueInterface.VALUE_VALID
