10.  def encoderFor(tpe: scala.reflect.api.JavaUniverse.Type, isRowEncoderSupported: Boolean = false): AgnosticEncoder[_]

    Create an AgnosticEncoder for a Type.

11.  def encoderFor[E](implicit arg0: scala.reflect.api.JavaUniverse.TypeTag[E]): AgnosticEncoder[E]

    Create an AgnosticEncoder from a TypeTag.

    Create an AgnosticEncoder from a TypeTag.

    If the given type is not supported, i.e. there is no encoder can be built for this type, an SparkUnsupportedOperationException will be thrown with detailed error message to explain the type path walked so far and which class we are not supporting. There are 4 kinds of type path: * the root type: root class: "abc.xyz.MyClass" * the value type of Option: option value class: "abc.xyz.MyClass" * the element type of Array or Seq: array element class: "abc.xyz.MyClass" * the field of Product: field (class: "abc.xyz.MyClass", name: "myField")

12.  def encoderForWithRowEncoderSupport[E](implicit arg0: scala.reflect.api.JavaUniverse.TypeTag[E]): AgnosticEncoder[E]

    Same as encoderFor but with extended support to return UnboundRowEncoder for Row type.

16.  def findConstructor[T](cls: Class[T], paramTypes: Seq[Class[_]]): Option[(Seq[AnyRef]) ⇒ T]

    Finds an accessible constructor with compatible parameters.

    Finds an accessible constructor with compatible parameters. This is a more flexible search than the exact matching algorithm in Class.getConstructor. The first assignment-compatible matching constructor is returned if it exists. Otherwise, we check for additional compatible constructors defined in the companion object as apply methods. Otherwise, it returns None.

19.  def getClassNameFromType(tpe: scala.reflect.api.JavaUniverse.Type): String

    Returns the full class name for a type.

    Returns the full class name for a type. The returned name is the canonical Scala name, where each component is separated by a period. It is NOT the Java-equivalent runtime name (no dollar signs).

    In simple cases, both the Scala and Java names are the same, however when Scala generates constructs that do not map to a Java equivalent, such as singleton objects or nested classes in package objects, it uses the dollar sign ($) to create synthetic classes, emulating behaviour in Java bytecode.

20.  def getConstructorParameterNames(cls: Class[_]): Seq[String]

    Returns the parameter names for the primary constructor of this class.

    Returns the parameter names for the primary constructor of this class.

    Logically we should call getConstructorParameters and throw away the parameter types to get parameter names, however there are some weird scala reflection problems and this method is a workaround to avoid getting parameter types.

21.  def getConstructorParameters(tpe: scala.reflect.api.JavaUniverse.Type): Seq[(String, scala.reflect.api.JavaUniverse.Type)]

    Returns the parameter names and types for the primary constructor of this type.

    Returns the parameter names and types for the primary constructor of this type.

    Note that it only works for scala classes with primary constructor, and currently doesn't support inner class.

    Return the Scala Type for T in the current classloader mirror.

    Use this method instead of the convenience method universe.typeOf, which assumes that all types can be found in the classloader that loaded scala-reflect classes. That's not necessarily the case when running using Eclipse launchers or even Sbt console or test (without fork := true).
