Examples of eu.stratosphere.types.StringValue

eu.stratosphere.types.StringValue
Mutable string data type that implements the Key interface. StringValue encapsulates the basic functionality of a {@link String}, in a serializable and mutable way.
The mutability allows to reuse the object inside the user code, also across invocations. Reusing a StringValue object helps to increase the performance, as string objects are rather heavy-weight objects and incur a lot of garbage collection overhead, if created and destroyed in masses. @see eu.stratosphere.types.Key @see eu.stratosphere.types.NormalizableKey @see java.lang.String @see java.lang.CharSequence
