Everything needed to run a comprehensive dev environment. Just type X_ and pick a service from autocomplete; new dev modules will be added as they are built. The only dev service not included in the uber jar is xapi-dev-maven, as it includes all runtime dependencies of maven, adding ~4 seconds to build time, and 6 megabytes to the final output jar size (without xapi-dev-maven, it's ~1MB).

The newest version!

package xapi.collect.impl;

/**
 * A very simple, but useful stack (linked list).
 * 
 * It's one-way, threadsafe, fast, toString friendly, and can merge with other
 * SimpleStacks easily via {@link #consume(SimpleStack)}
 * 

 * Note that neither remove() nor size() are not supported.
 * 
 * If you need a list or a map, use one. This class is for pushing together
 * references, iterating through them, and maybe joining them into a string.
