Class LowLevelHttpRequest

java.lang.Object
com.google.api.client.http.LowLevelHttpRequest
Direct Known Subclasses:
Apache5HttpRequest, MockLowLevelHttpRequest
public abstract class LowLevelHttpRequest extends Object
Low-level HTTP request.

This allows providing a different implementation of the HTTP request that is more compatible with the Java environment used.

Implementation has no fields and therefore thread-safe, but sub-classes are not necessarily thread-safe.
