The PlainText "tree" provides a hook into the source code generation.
The PlainText "tree" provides a hook into the source code generation.
When a PlainText tree occurs during source code generation, its print
method is called with the current AbstractPrinter#PrintingContext. The
result is inserted into the generated source code.
For some use cases (blank line, raw and indented string) implementations
already exist in the PlainText object.
Note that PlainText trees should never be allowed to escape the Scala refactoring library, so be careful when using compiler utilities to transform trees.
PrintingContext is passed around with all the print methods and contains the context or environment for the current printing.

Extracts information from ApplyNodes
Extracts information from ApplyNodes
The main feature of this extractor is that reverses the desugarings the compiler performs for named arguments by creating scala.tools.refactoring.common.EnrichedTrees.NamedArgument instances as necessary. Apart from that, this object is meant to mimic the regular scala.reflect.api.Trees.ApplyExtractor.
Unify the children of a Block tree and sort them in the same order they appear in the source code.
Unify the children of a Block tree and sort them in the same order they appear in the source code.
Also reshapes some trees: multiple assignments are removed and named argument trees are created.
Note that this extractor is needed primarily for tree printing. The rename refactoring for example, that doesn't use tree printing, would work with
object BlockExtractor { def unapply(t: Block) = { Some(t.expr :: t.stats) } }
as well.
Extract the modifiers with their position from a Modifiers object.

When extracting source code from the file via a tree's position, it depends on the tree type whether we can use the position's start or point.

The tree that will be replaced.
The position to adapt. This does not have to be the position of t.
Returns the (symbol) ancestors of the tree excluding the ROOT in descending order. Also filters the symbols for package objects!
Converts a tree containing Idents and Selects to a . separated string.

Returns all children that have a representation in the source code.
Returns all children that have a representation in the source code. This includes Name and Modifier trees and excludes everything that has no Position or is an EmptyTree.
Creates a list of TextChanges from a list of trees, regenerating only those trees that have changed.

If the sourceFile parameter is passed, it will be used to figure out what kinds of newline separators we should generate. If None is passed, '\n' is used.

Takes a name and wraps it in if the name corresponds to a Scala keyword.

Starting from a root tree, returns all children that have changed.
Starting from a root tree, returns all children that have changed. The format of the result is a tuple of a top-level tree, a position of the range that should be replaced and a set of all trees that changed in the context of that top-level tree, including the top-level tree.
Finds a tree by its position, can be used to find the original tree from a transformed tree.

If multiple trees are candidates, then take the last one, because it is likely more specific.
Searches for a Symbol of a name in the type members of a tree.

This is mainly used for ImportSelectors, which don't carry any symbol information with them.
The expr of an Import tree.
The name of an ImportSelector of the import.
Returns whether the tree is considered empty.
Returns whether the tree is considered empty.
Prior to Scala 2.10.1 it was sufficient to check Tree#isEmpty, but now we also need to check if the tree is equal to emptyValDef.

Returns the most specific package declaration in the compilation
unit. For example, given the following declaration:
package a
package b
class C
it returns b. If there are further nested packages, they are ignored:
package a
class C
package b
returns a.
