  String getClassName()

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

  Returns:

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

  SeeThe Java™ Language Specification:

  13.1 The Form of a Binary

• getMethodName

  String getMethodName()

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

  Returns:

  the name of the method represented by this stack frame

• getDeclaringClass

  Class<?> getDeclaringClass()

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

  Returns:

  the declaringClass of the method represented by this stack frame

  Throws:

  UnsupportedOperationException - if thisStackWalker is not configured withOption.RETAIN_CLASS_REFERENCE.

• getByteCodeIndex

  int getByteCodeIndex()

  Returns the index to the code array of theCode attribute containing the execution point represented by this stack frame. The code array gives the actual bytes of Java Virtual Machine code that implement the method.

  Returns:

  the index to the code array of theCode attribute containing the execution point represented by this stack frame, or a negative number if the method is native.

  SeeThe Java™ Virtual Machine Specification:

  4.7.3 TheCode Attribute

• getFileName

  String getFileName()

  Returns the name of the source file containing the execution point represented by this stack frame. Generally, this corresponds to theSourceFile attribute of the relevantclass file as defined byThe Java Virtual Machine Specification. In some systems, the name may refer to some source code unit other than a file, such as an entry in a source repository.

  Returns:

  the name of the file containing the execution point represented by this stack frame, ornull if this information is unavailable.

  SeeThe Java™ Virtual Machine Specification:

  4.7.10 TheSourceFile Attribute

• getLineNumber

  int getLineNumber()

  Returns the line number of the source line containing the execution point represented by this stack frame. Generally, this is derived from theLineNumberTable attribute of the relevantclass file as defined byThe Java Virtual Machine Specification.

  Returns:

  the line number of the source line containing the execution point represented by this stack frame, or a negative number if this information is unavailable.

  SeeThe Java™ Virtual Machine Specification:

  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.

• toStackTraceElement

  StackTraceElement toStackTraceElement()

  Gets aStackTraceElement for this stack frame.

  Returns:

  StackTraceElement for this stack frame.
