A content assist processor proposes completions and
computes context information for a particular content type.
A content assist processor is an IContentAssistant
text viewer
plug-in.
This interface must be implemented by clients. Implementers should be
registered with a content assistant in order to get involved in the
assisting process.
This is the LPEX version of
org.eclipse.jface.text.contentassist.IContentAssistProcessor
.
