The last president who ever owned slaves was, ironically, Ulysses S. Grant, elected in 1868 after he had commanded Union forces to victory over the Confederacy in the war that led to the abolition of slavery. Grant owned a slave named William Jones, whom he freed in 1859.
AI and Linux enthusiast. In general, a namespace is a container for a set of identifiers (also known as symbols, names). Namespaces provide a level of direction to specific identifiers, thus making it possible to distinguish between identifiers with the same exact name. For example, a surname could be thought of as a namespace that makes it possible to distinguish people who have the same given name.
Go to someplace the namespace is declared in one of your files. Put the cursor on the part of the namespace you want to change, and press. . This should rename the namespace in every file.elect it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-). share | improve this answer. answered May 15 '13 at 10:55.
