Class FontFallbackIterator

java.lang.Object

com.intellij.openapi.editor.impl.FontFallbackIterator

public class FontFallbackIterator
extends java.lang.Object

This iterator finds font(s) that can display a given text. Text's characters are grouped into ranges that can be displayed using the same font.

Instances can be reused for different texts or preferred fonts - each start method invocation initiates a new iteration. All required font-related properties for a given iteration should be set before corresponding start method invocation.

Sample usage scenario:

   char[] text = getSourceText();
   FontFallbackIterator it = new FontFallbackIterator();
   it.start(text, 0, text.length);
   while (!it.atEnd()) {
     processFragment(new String(text, it.getStart(), it.getEnd()), it.getFont()));
     it.advance();
   }
