SyntheticMapRemoval (Apache Sling Scripting HTL Compiler 1.2.14-1.4.0 API)

java.lang.Object
- org.apache.sling.scripting.sightly.impl.compiler.visitor.UniformVisitor
- - org.apache.sling.scripting.sightly.impl.compiler.visitor.TrackingVisitor<MapLiteral>
  - - org.apache.sling.scripting.sightly.impl.compiler.optimization.SyntheticMapRemoval

All Implemented Interfaces:

CommandVisitor, EmitterVisitor
```
public final class SyntheticMapRemoval
extends TrackingVisitor<MapLiteral>
implements EmitterVisitor
```
This optimization handles variables initialized to map literals. It initially assigns the values in the map to variables and wherever the map literal is accessed, the property access is replaced with the value variable, thus removing the need for a map lookup.
