## Content types

The org.eclipse.core.runtime.content package provides support for detecting the content type for data streams. Content types are used by several content-sensitive features of Eclipse, such as automatic encoding determination, editor selection, and menu contributions. A central content registry allows plug-ins to request content type detection and to find out what content types are available and how they related to each other. The content type registry is extensible so plug-ins can contribute new content type definitions.
