RewriteBuffer - As code is rewritten, SourceBuffer's from the original input with modifications get a new RewriteBuffer associated with them.

The RewriteBuffer captures the modified text itself as well as information used to map between SourceLocation's in the original input and offsets in the RewriteBuffer. For example, if text is inserted into the buffer, any locations after the insertion point have to be mapped.

◆ Initialize() [1/2]

Initialize - Start this rewrite buffer out with a copy of the unmodified input buffer.

◆ Initialize() [2/2]

void llvm::RewriteBuffer::Initialize ( StringRef Input) inline

◆ InsertText()

InsertText - Insert some text at the specified point, where the offset in the buffer is specified relative to the original SourceBuffer.

The text is inserted after the specified location.

◆ InsertTextAfter()

InsertTextAfter - Insert some text at the specified point, where the offset in the buffer is specified relative to the original SourceBuffer.

The text is inserted after the specified location.

Definition at line 84 of file RewriteBuffer.h.

References InsertText().

◆ InsertTextBefore()

InsertTextBefore - Insert some text before the specified point, where the offset in the buffer is specified relative to the original SourceBuffer.

The text is inserted before the specified location. This is method is the same as InsertText with "InsertAfter == false".

Definition at line 77 of file RewriteBuffer.h.

References InsertText().

◆ RemoveText()

void RewriteBuffer::RemoveText ( unsigned OrigOffset,
unsigned Size,
bool removeLineIfEmpty = false )

◆ ReplaceText()

◆ size()

unsigned llvm::RewriteBuffer::size ( ) const inline

◆ write()

Write to Stream the result of applying all changes to the original buffer.

Note that it isn't safe to use this function to overwrite memory mapped files in-place (PR17960). Consider using a higher-level utility such as Rewriter::overwriteChangedFiles() instead.

The original buffer is not actually changed.
