Detailed Description

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.

◆ IncreaseIndentation() [1/2]

bool Rewriter::IncreaseIndentation	(	CharSourceRange	range,
		SourceLocation	parentIndent
	)

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.

◆ InsertText()

bool Rewriter::InsertText	(	SourceLocation	Loc,
		StringRef	Str,
		bool	InsertAfter = `true`,
		bool	indentNewLines = `false`
	)

InsertText - 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.

Parameters

indentNewLines if true new lines in the string are indented using the indentation of the source line in position Loc.

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).
