Class RMXString

com.reportmill.text.RMXString

All Implemented Interfaces:

RMTypes, RMTextTypes, java.lang.CharSequence

public class RMXString
extends SnapObject
implements java.lang.CharSequence, RMTextTypes

An RMXString is like a String that lets you apply attributes, like fonts and colors, to character ranges. These character ranges with common attributes are represented internally as the inner class Run. You might use it like this:

    RMXString xstring = new RMXString("Hello World", RMColor.red);
    xstring.addAttribute(RMFont.getFont("Arail Bold", 12), 0, 5);
    xstring.addAttribute(RMFont.getFont("Arial BoldItalic", 12), 6, xstring.length());
 

Advanced applications, that need to disect or render strings, might iterate over the runs like this:

    for(int i=0; i
