Delegates the transformation strategy to scala.reflect.internal.Trees,
because pattern matching on abstract types we have here degrades performance.

Use reify to produce the abstract syntax tree representing a given Scala expression.
Use reify to produce the abstract syntax tree representing a given Scala expression.
For example:
val five = reify{ 5 } // Literal(Constant(5)) reify{ 5.toString } // Apply(Select(Literal(Constant(5)), TermName("toString")), List()) reify{ five.splice.toString } // Apply(Select(five, TermName("toString")), List())
The produced tree is path dependent on the Universe reify was called from.
Use scala.reflect.api.Exprs#Expr.splice to embed an existing expression into a reify call. Use Expr to turn a Tree into an expression that can be spliced.

Renders the code of the passed tree, so that: 1) it can be later compiled by scalac retaining the same meaning, 2) it looks pretty.
Renders the code of the passed tree, so that: 1) it can be later compiled by scalac retaining the same meaning, 2) it looks pretty. #1 is available for unattributed trees and attributed trees #2 is more or less okay indentation-wise, but at the moment there's a lot of desugaring left in place, and that's what we plan to improve in the future. printTypes, printIds, printPositions options have the same meaning as for TreePrinter printRootPkg option is available only for attributed trees.

The methods available for each reflection entity, without the implementation. Since the reflection entities are later overridden by runtime reflection and macros, their API counterparts guarantee a minimum set of methods that are implemented.
Extractors provide the machinery necessary to allow pattern matching and construction of reflection entities that is similar to case classes, although the entities are only abstract types that are later overridden.
EXPERIMENTAL
A refinement of scala.reflect.api.Universe for runtime reflection using JVM classloaders.
This refinement equips mirrors with reflection capabilities for the JVM.
JavaMirrorcan convert Scala reflection artifacts (symbols and types) into Java reflection artifacts (classes) and vice versa. It can also perform reflective invocations (getting/setting field values, calling methods, etc).See the Reflection Guide for details on how to use runtime reflection.
