Note that for an encoder, no input can cause an error; the possible errors result either from a call to the `convert` method after the `endConvert` method is called the first time, or from a call to either the `convert` or the `endConvert` methods after the `endConvert` method has returned successfully. == Synopsis Declared in `<bdlde_quotedprintableencoder.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- bool isError() const; ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
