Class InlineStyles

java.lang.Object
com.codename1.ui.editor.InlineStyles
public final class InlineStyles extends Object
The per character inline style model for the pure rich text editor. It keeps one TextStyle reference for every character in the document, kept in lockstep with the text through #applyEdit. Runs of identical style are coalesced only at render time, which keeps edits simple and correct at the cost of one reference per character (rich documents are small enough for this to be a non issue).
