InstanceMirror

Reflects against an inner class symbol and returns a mirror that can be used to create instances of the class, inspect its companion object or perform further reflections.

To get a class symbol by the name of the class you would like to reflect, use <this mirror>.symbol.typeSignature.member(newTypeName(<name of the class>)).asClass. For further information about member lookup refer to Symbol.typeSignature.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.

Reflects against a field symbol and returns a mirror that can be used to get and, if appropriate, set the value of the field.

FieldMirrors are the only way to get at private[this] vals and vars and might be useful to inspect the data of underlying Java fields. For all other uses, it's better to go through the fields accessor.

In particular, there should be no need to ever access a field mirror when reflecting on just the public members of a class or trait. Note also that only accessor MethodMirrors, but not FieldMirrors will accurately reflect overriding behavior.

To get a field symbol by the name of the field you would like to reflect, use <this mirror>.symbol.typeSignature.member(newTermName(<name of the field>)).asTerm.accessed. For further information about member lookup refer to Symbol.typeSignature.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the class of the instance underlying this mirror.

The input symbol can represent either a field itself or one of the corresponding accessors (in all cases the resulting mirror will refer to the field symbol).

If a field symbol doesn't correspond to a reflectable entity of the underlying platform, a ScalaReflectionException exception will be thrown. This might happen, for example, for primary constructor parameters. Typically they produce class fields, however, private parameters that aren't used outside the constructor remain plain parameters of a constructor method of the class.

Reflects against a method symbol and returns a mirror that can be used to invoke the method provided.

To get a method symbol by the name of the method you would like to reflect, use <this mirror>.symbol.typeSignature.member(newTermName(<name of the method>)).asMethod. For further information about member lookup refer to Symbol.typeSignature.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.

Reflects against an inner module symbol and returns a mirror that can be used to get the instance of the object or inspect its companion class.

To get a module symbol by the name of the object you would like to reflect, use <this mirror>.symbol.typeSignature.member(newTermName(<name of the object>)).asModule. For further information about member lookup refer to Symbol.typeSignature.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.

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.

Test two objects for equality. 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 (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:

• 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.

Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).

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.
