Represent an import selector as a tree, including both names as trees.
Import selectors are not trees, but we can provide an extractor that converts the ImportSelectors into our own ImportSelectorTrees.
Represent a modifier as a tree, including its position.
Represent a Name as a tree, including its position.
The PlainText "tree" provides a hook into the source code generation.
Representation of self type annotations: self: A with B => ^^^^^^^^^^^^^^
The call to the super constructor in a class: class A(i: Int) extends B(i) ^^^^
Add some methods to Tree that make it easier to compare Trees by position and to extract the position of a tree's name, which is tricky for Selects.
A SourceLayoutTree can be used to insert arbitrary text into the code, for example, blank lines.
Unify the children of a Block tree and sort them in the same order they appear in the source code.
Extract the modifiers with their position from a Modifiers object.
Provides a finer-grained extractor for Template that distinguishes between class constructor parameters, early definitions, parents, self type annotation and the real body.
Copy of scala.reflect.internal.Trees.ValOrDefDef of 2.
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.
Trees that reach the end of the file don't seem to have the correct end position, except if there's a newline at the end.
Takes a name and wraps it in if the name corresponds to a Scala keyword.
Finds a tree by its position, can be used to find the original tree from a transformed 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.
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.
(Since version 0.5.0) Use PlainText objects and its components
A collection of implicit conversions for ASTs and other helper functions that work on trees.
