  Returns:

  thebinary name of the declaring class of the method represented by this stack frame

  SeeJava Language Specification:

  13.1 The Form of a Binary
  

• getMethodName

  String getMethodName()

  Returns the name of the method represented by this stack frame.

  Returns:

  the name of the method represented by this stack frame

  Throws:

  UnsupportedOperationException - if theStackWalker is configured withDROP_METHOD_INFO option

• getDeclaringClass

  Class<?> getDeclaringClass()

  Returns the declaringClass for the method represented by this stack frame.

  Returns:

  the declaringClass for the method represented by this stack frame

  Throws:

  UnsupportedOperationException - if theStackWalker is configured withoutRETAIN_CLASS_REFERENCE option

• getMethodType

  default MethodType getMethodType()

  Returns theMethodType representing the parameter types and the return type for the method represented by this stack frame.

  Implementation Requirements:

  The default implementation throwsUnsupportedOperationException.

  Returns:

  theMethodType of the method represented by this stack frame

  Throws:

  UnsupportedOperationException - if theStackWalker is configured withDROP_METHOD_INFO option or withoutRETAIN_CLASS_REFERENCE option

  Since:

  10

  4.7.12 TheLineNumberTable Attribute
  

• isNativeMethod

  boolean isNativeMethod()

  Returnstrue if the method containing the execution point represented by this stack frame is a native method.

  Returns:

  true if the method containing the execution point represented by this stack frame is a native method
