Method Detail

getCallerClass

public scala.Option<scala.Function1<java.lang.Object,java.lang.Class<?>>> getCallerClass()

This optionally holds a function which looks N levels above itself on the call stack and returns the Class[_] object for the code executing in that stack frame. Implemented using sun.reflect.Reflection.getCallerClass if available, None otherwise.

Hint: when comparing to Thread.currentThread.getStackTrace, add two levels.

Returns:

(undocumented)

instantiate

public <T> T instantiate(java.lang.Class<T> clazz)

INTERNAL API

Parameters:

clazz - the class which to instantiate an instance of

Returns:

a new instance from the default constructor of the given class

instantiate

public <T> T instantiate(java.lang.Class<T> clazz,
                         scala.collection.immutable.Seq<java.lang.Object> args)

INTERNAL API Calls findConstructor and invokes it with the given arguments.

Parameters:

clazz - (undocumented)

args - (undocumented)

Returns:

(undocumented)

instantiate

public <T> T instantiate(java.lang.reflect.Constructor<T> constructor,
                         scala.collection.immutable.Seq<java.lang.Object> args)

INTERNAL API Invokes the constructor with the the given arguments.

Parameters:

constructor - (undocumented)

args - (undocumented)

Returns:

(undocumented)

findConstructor

public <T> java.lang.reflect.Constructor<T> findConstructor(java.lang.Class<T> clazz,
                                                            scala.collection.immutable.Seq<java.lang.Object> args)

INTERNAL API Implements a primitive form of overload resolution a.k.a. finding the right constructor.

Parameters:

clazz - (undocumented)

args - (undocumented)

Returns:

(undocumented)

instantiator

public <T> scala.Function0<T> instantiator(java.lang.Class<T> clazz)

INTERNAL API

Parameters:

clazz - the class which to instantiate an instance of

Returns:

a function which when applied will create a new instance from the default constructor of the given class

findMarker

public java.lang.reflect.Type findMarker(java.lang.Class<?> root,
                                         java.lang.Class<?> marker)
