paramString

public String paramString()

toString

public String toString()

Description copied from class: Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:

toString in class Object

Returns:

the String representing this Object, which may be null

See Also:

Object.getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)

getValueIsAdjusting

public boolean getValueIsAdjusting()

Returns true if the value is in the process of changing.

Since:

1.4

setValueIsAdjusting

public void setValueIsAdjusting(boolean valueIsAdjusting)

Sets the value of valueIsAdjusting.

Since:

1.4
