Class GetOptions

java.lang.Object

org.jclouds.blobstore.options.GetOptions

public class GetOptions
extends Object

Contains options supported for HTTP GET operations.

Usage

The recommended way to instantiate a GetOptions object is to statically import GetOptions.Builder.* and invoke a static creation method followed by an instance mutator (if needed):

import static org.jclouds.blobstore.options.GetOptions.Builder.* // this will get the first megabyte of an blob, provided it wasn't modified since yesterday blob = blobStore.getBlob("container, "blobName",range(0,1024).ifUnmodifiedSince(new Date().minusDays(1)));
