Class SmallIntStrings

java.lang.Object
org.ek9lang.compiler.support.SmallIntStrings
All Implemented Interfaces:
IntFunction<String>
public final class SmallIntStrings extends Object implements IntFunction<String>
THE shared cache of small non-negative int-to-String conversions — use this instead of String.valueOf(int) / Integer.toString(int) when the result is squirrelled or otherwise retained per symbol.

String.valueOf(n) allocates a fresh ~48 B String on every call, so stamping a metric (COMPLEXITY, COGNITIVE_COMPLEXITY, ...) on tens of thousands of symbols leaves tens of thousands of distinct String objects even though the underlying values repeat heavily (a handful of small integers). Returning a shared, pre-computed String for 0..1024-1 collapses those to one object per distinct value — retained-heap saving, not just churn.
