getChanged

public boolean getChanged()

Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

getChanged in interface Changeable

Returns:

true if the object has been changed and needs recalculation; false otherwise

getChanged

public boolean getChanged(int mask)

Checks the value of the ChangedFlag property for the specified mask (see Changeable for a list of valid masks). The ChangedFlag property determines the action the object needs to take in regards to the current change.

Specified by:

getChanged in interface Changeable

Parameters:

mask - the mask with which to check

Returns:

true if the specified mask exists in the ChangedFlag property; false otherwise

isChanged

public final boolean isChanged()

Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

isChanged in interface Changeable

Returns:

true if the object has been changed and needs recalculation; false otherwise

isChanged

public final boolean isChanged(int mask)

Checks the value of the ChangedFlag property for the specified mask (see Changeable for a list of valid masks). The ChangedFlag property determines the action the object needs to take in regards to the current change.

Specified by:

isChanged in interface Changeable

Parameters:

mask - the mask with which to check

Returns:

True if the specified mask exists in the ChangedFlag property; false otherwise

setChanged

public void setChanged(boolean n,
                       int cf)

Sets the value of the Changed property and updates the parent object. The Changed property determines whether the object needs to be recalculated.

Specified by:

setChanged in interface Changeable

Parameters:

n - new value for Changed

cf - the value with which to update the changed flag

setChanged

public void setChanged(boolean n,
                       int cf,
                       boolean updateParent)

Sets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

setChanged in interface Changeable
