Examples of com.google.collide.dto.DocOp

com.google.collide.dto.DocOp
Models a document operation for the Collide code editor. A DocOp is a description for an operation to be performed on the document. It consists of one or more components that together must span the entire length of the document. For example, consider the following DocOp which spans the document with three lines: {(RetainLine:1), (Insert:"Hello"), (Retain:5, true), (RetainLine:1)}. It retains the first line, inserts "Hello" at the beginning of the second line, retains the remaining 5 characters on that second line (including the newline), and then retains the last line.
