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 -

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 -

Returns:

True if the specified mask exists in the ChangedFlag property, false otherwise.

updateFlags

protected void updateFlags(boolean n,
                           int cf)

Update the "changed" flag and the "ChangedFlag" mask.
