ToolBox

Indicates that an argument to c.typecheck should be typechecked as a term. This is the default typechecking mode in Scala 2.11 and the only one supported in Scala 2.10.

Compiles a tree using this ToolBox.

If the tree has unresolved type variables (represented as instances of FreeTypeSymbol symbols), then they all have to be resolved first using Tree.substituteTypes, or an error occurs.

This spawns the compiler at the Namer phase, and pipelines the tree through that compiler. Currently compile does not accept trees that already typechecked, because typechecking isn't idempotent. For more info, take a look at https://issues.scala-lang.org/browse/SI-5464.

Defines a top-level class, trait or module in this ToolBox, putting it into a uniquely-named package and returning a symbol that references the defined entity. For a ClassDef, a ClassSymbol is returned, and for a ModuleDef, a ModuleSymbol is returned (not a module class, but a module itself).

This method can be used to generate definitions that will later be re-used by subsequent calls to compile, define or eval. To refer to the generated definition in a tree, use q"$sym".

Compiles and runs a tree using this ToolBox. Is equivalent to compile(tree)().

Front end of the toolbox.

Accumulates and displays warnings and errors, can drop to interactive mode (if supported). The latter can be useful to study the typechecker or to debug complex macros.

scala.tools.reflect provides two predefined front ends that can be created using scala.tools.reflect.mkSilentFrontEnd and scala.tools.reflect.mkConsoleFrontEnd.

Infers an implicit value of the expected type pt in top-level context. Optional pos parameter provides a position that will be associated with the implicit search.

As mentioned in https://groups.google.com/forum/#!topic/scala-internals/ta-vbUT6JE8 this API won't take into account the lexical context of the callsite, because currently it's impossible to reify it.

If silent is false, ToolBoxError will be thrown in case of an inference error. If silent is true, the typecheck is silent and will return EmptyTree if an error occurs. Such errors don't vanish and can be inspected by turning on -Xlog-implicits. Unlike in typecheck, silent is true by default.

Infers an implicit view from the provided tree tree from the type from to the type to in the toplevel context. Optional pos parameter provides a position that will be associated with the implicit search.

Typechecks a tree against the expected type pt under typechecking mode specified in mode with EXPRmode being default. This populates symbols and types of the tree and possibly transforms it to reflect certain desugarings.

If the tree has unresolved type variables (represented as instances of FreeTypeSymbol symbols), then they all have to be resolved first using Tree.substituteTypes, or an error occurs.

If silent is false, ToolBoxError will be thrown in case of a typecheck error. If silent is true, the typecheck is silent and will return EmptyTree if an error occurs. Such errors don't vanish and can be inspected by turning on -Ydebug.

Typechecking can be steered with the following optional parameters: withImplicitViewsDisabled recursively prohibits implicit views (though, implicit vals will still be looked up and filled in), default value is false withMacrosDisabled recursively prohibits macro expansions and macro-based implicits, default value is false

Recursively resets locally defined symbols and types in a given tree. WARNING: Don't use this API, go for untypecheck instead.

Test two objects for inequality.

Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Cast the receiver object to be of type T0.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

Create a copy of the receiver object.

The default implementation of the clone method is platform dependent.

Tests whether the argument (that) is a reference to the receiver object (this).

The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

• It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
• For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
• null.eq(null) returns true.

When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

The equality method for reference types. Default implementation delegates to eq.

See also equals in scala.Any.

Called by the garbage collector on the receiver object when there are no more references to the object.

The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.

A representation that corresponds to the dynamic class of the receiver object.

The nature of the representation is platform dependent.

The hashCode method for reference types. See hashCode in scala.Any.

Test whether the dynamic type of the receiver object is T0.

Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

Equivalent to !(this eq that).

Wakes up a single thread that is waiting on the receiver object's monitor.

Wakes up all threads that are waiting on the receiver object's monitor.

Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.
