A factory which can create a package def from a prototype and a list of declarations.
Adds a list of top-level definitions to the compiler's symbol table.
Adds a list of top-level definitions to the compiler's symbol table. _TOP_LEVEL Allowed definitions include classes (represented by ClassDef
trees), traits (represented
by ClassDef
trees having the TRAIT
flag set in mods
) and objects (represented by ModuleDef
trees).
The definitions are put into the package with a prototype provided in packagePrototype
.
Supported prototypes are (see PackageSpec for more details):
* Strings and names representing a fully-qualified name of the package
* Trees that can work as package ids
* Package or package class symbols
Typical value for a package prototype is a fully-qualified name in a string.
For example, to generate a class available at foo.bar.Test
, call this method as follows:
introduceTopLevel("foo.bar", ClassDef(<mods>, TypeName("Test"), <tparams>, <template>))
It is possible to add definitions to the empty package by using nme.EMPTY_PACKAGE_NAME.toString
, but
that's not recommended, since such definitions cannot be seen from outside the empty package.
Only the multi-parameter overload of this method can be used to introduce companions.
If companions are introduced by two different calls, then they will be put into different virtual files, and scalac
will show an error about companions being defined in different files. By the way, this also means that there's currently no way
to define a companion for an existing class or module_TOP_LEVEL.
Returns a list of fully-qualified references to the introduced definitions.

Returns a fully-qualified reference to the introduced definition.
Looks up a top-level definition tree with a given fully-qualified name (term name for modules, type name for classes).
Looks up a top-level definition tree with a given fully-qualified name
(term name for modules, type name for classes). _TREE Top-level tree is a tree that represents a non-inner class or object in one of the currently compiled source files.
Note that top-level isn't equivalent to scala.reflect.api.Symbols#SymbolApi.isStatic,
because static also embraces definitions nested in static objects
_TREE.
If such a tree does not exist, returns EmptyTree
.
Returns a reference to a top-level definition tree with a given fully-qualified name (term name for modules, type name for classes).

Equivalent to x.hashCode

.
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
.

Test two objects for equality.
Test two objects for equality.
The expression x == that
is equivalent to if (x eq null) that eq null else x.equals(that)
.
true
if the receiver object is equivalent to the argument; false
otherwise.
Hosts supported package specs.
Cast the receiver object to be of type T0
.
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.
Tests whether the argument (arg0

Tests whether the argument (arg0
) 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:
x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.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
).
true
if the argument is a reference to the receiver object; false
otherwise.
The equality method for reference types.
Called by the garbage collector on the receiver object when there are no more references to the object.
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.

Returns string formatted according to given format

Format strings are as for String.format
(@see java.lang.String.format).

The hashCode method for reference types.
Test whether the dynamic type of the receiver object is T0
.
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.
