org.jacoco.core.analysis.StringPool
public final class StringPool
- extends Object
Utility to normalize String
instances in a way that if
equals()
is true
for two strings they will be
represented the same instance. While this is exactly what
String.intern()
does, this implementation avoids VM specific side
effects and is supposed to be faster, as neither native code is called nor
synchronization is required for concurrent lookup.
