Interface ConnectionManager

All Known Subinterfaces:
ResumableConnectionManager
All Known Implementing Classes:
HttpConnectionManager
public interface ConnectionManager
A connection manager is used to access the contents and metadata about the resource pointed to by a given URI. Connection managers are usually created by ConnectionManagerFactory objects. Implementations doesn't have to be thread-safe since a new connection manager is created for each use of an URI. Implementations doens't have to provide a public no-argument constructor.

NOTE! Also consider implementing the ResumableConnectionManager interface if the protocol supports setting a start offset for the download.
