This is yet another one.
How to use:
sealed trait DummyEnum object DummyEnum extends Enum[DummyEnum] { val values = findValues case object Hello extends DummyEnum case object GoodBye extends DummyEnum case object Hi extends DummyEnum } DummyEnum.values should be(Set(Hello, GoodBye, Hi)) DummyEnum.withName("Hello") should be(Hello)

This provides an immutable milliseconds since epoch representation of a date when it might be a mismatch to use the newer java.time.Instance (which represents things as nanoseconds since or before epoch)

Wraper around Guava's Interner class.
Wraper around Guava's Interner class.
Originally I had a generic Intern object that had a map of Class[_] to Guava Interner but that relies on a correct implementation of equals which can make it error prone. For Example an Option[Char] can == an Option[Int]. So instead you have to be explicit about creating an Interner.

Compatible with the Rails MessageEncryptor using 'aes-256-cbc' and MessageVerifier using 'sha1' when working with *String* values.
Also compatible with the custom MessageCrypto which marshalls values as JSON instead of using the ruby Marshal.dump and Marshal.load. Use json=true to dump using JSON.
MessageEncryptor uses Marshal.dump and Marshal.load on whatever values you are trying to encrypt/sign. A subset of Marshal.dump and Marshal.load have been implemented to support String values.
NOTE: This is a legacy class that was created when we switched from Rails to Scala. It is still used in a few places but probably needs to be refactored to remove the old Ruby marshalling stuff.

An Automatically Managed Resource that can either be used once (e.g.
An Automatically Managed Resource that can either be used once (e.g. reading an input stream) or multiple times (e.g. reading a file).
The purpose of Resource is two-fold: 1 - To automatically handle closing a resource after it is done being used. 2 - To abstract the fact that some resources can be read multiple times while other resources are one-time use.
This is a replacement for the deprecated scala.collection.SeqProxy.

This doesn't implement Seq[A] like the original SeqProxy but instead just provides an implicit conversion from this trait into a Seq[A] which then gives you all the Seq functionality

The initial use case of this is for caching NumberFormat instances by Locale. This can be accomplished by overriding the initialValue method and just calling the apply() method with the Locale.

A custom UUID implementation (not to be confused with java.util.UUID or RFC4122 implementations) that allows natural sorting by timestamp based on the string or numeric representation.
A custom UUID implementation (not to be confused with java.util.UUID or RFC4122 implementations) that allows natural sorting by timestamp based on the string or numeric representation.
The UUID consists of 16 bytes (128 bits) broken up into 2 longs:
timeAndCounter: {6-Byte Millis since epoch}{2-Byte Counter} nodeIdAndRandom: {2-Byte Node ID}{6-Byte Random Number}
The "pretty" hex encoded representation is: {6-byte millis since epoch}-{2-byte-counter}-{2-byte-optional-node-id}-{4-byte-random}
Example: 015247f01787-9740-85e0-3e9672a8dfa2

An UUID wrapper class that allow you to define custom types that represent an UUID.
The intended usage pattern is something like:
object UserId extends UUIDFactory[UserId](new UserId(_)) final class UserId(val uuid: UUID) extends UUIDWrapper[UserId]
This allows you to then reference UserId instead of UUID and to have methods that take a strongly typed UserId instead of an UUID (which could represent something other than a User id)
Note: The class that extends this should also extends AnyVal so that serialization will just pass through to the underlying uuid

An object pool based on a WeakHashMap (using weak key AND weak values) that can be used to return canonical versions of objects. Once all references to the object go away the WeakHashMap entry will be GC'd.
This is similar to how String.intern() works (although probably not as efficient)

Base58 is a way to encode Bitcoin addresses (or arbitrary data) as alphanumeric strings.
Base58 is a way to encode Bitcoin addresses (or arbitrary data) as alphanumeric strings.
Note that this is not the same base58 as used by Flickr, which you may find referenced around the Internet.
You may want to consider working with PrefixedChecksummedBytes instead, which
adds support for testing the prefix and suffix bytes commonly found in addresses.
Satoshi explains: why base-58 instead of standard base-64 encoding?
However, note that the encoding/decoding runs in O(n²) time, so it is not useful for large data.
The basic idea of the encoding is to treat the data bytes as a large number represented using base-256 digits, convert the number to be represented using base-58 digits, preserve the exact number of leading zeros (which are otherwise lost during the mathematical operations on the numbers), and finally represent the resulting base-58 digits as alphanumeric ASCII characters.

This contains utility methods for scanning Classes or Files on the classpath.
Originally we used the classpath scanning functionality in the Spring Framework and then later switched to the Reflections library (https://code.google.com/p/reflections/) to avoid the dependency on Spring. At some point we ran into issues with the Reflections library not properly detecting classes so I ended up writing this as a replacement.

Originally I attempted to have the Charset directly encode the BOM (like the UTF-16 Charsets) but ran into problems with not being able to call into protected methods of the UTF-8 Charset implementation and did not want to copy/paste a bunch of code and/or implement a bunch of hacks to make it work properly.
