Constructor Detail

NativeRange

protected NativeRange()

Default constructor. Needs to be protected because all instances are created from JavaScript.

Method Detail

select

public final void select()

Makes the selection equal to the current object. When applied to a TextRange object, the select method causes the current object to be highlighted. When applied to a ControlRange object, the select method produces a shaded rectangle around the elements in the control range.

getOwnerDocument

public final Document getOwnerDocument()

Returns:

The document used to create this range.

isTextRange

public final boolean isTextRange()

This method is needed because instanceof operator returns true all the time when applied on a overlay type. For instance:

 TextRange textRange = TextRange.newInstance(doc);
 boolean result = textRange instanceof TextRange; // result is true, which is right.
 result = textRange instanceof ControlRange // result is also true, which is wrong.
 

Returns:

true if this is a text range, and false if it is a control range.
