Rewriter - This is the main interface to the rewrite buffers.
Its primary job is to dispatch high-level requests to the low-level RewriteBuffers that are involved.

RewriteBuffer & Rewriter::getEditBuffer | ( | FileID | FID | ) |
getEditBuffer - This is like getRewriteBufferFor, but always returns a buffer, and allows you to write on it directly.
getEditBuffer - Get or create a RewriteBuffer for the specified FileID.
This is useful if you want efficient low-level access to apis for scribbling on one specific FileID's buffer.

bool Rewriter::IncreaseIndentation | ( | CharSourceRange | range, |

Increase indentation for the lines between the given source range.
To determine what the indentation should be, 'parentIndent' is used that should be at a source location with an indentation one degree lower than the given range.

InsertTextAfter - Insert the specified string at the specified location in the original buffer.
This method returns true (and does nothing) if the input location was not rewritable, false otherwise. Text is inserted after any other text that has been previously inserted at the some point (the default behavior for InsertText).
