Interface StackWalker.StackFrame

Method Details

• getClassName

  String getClassName()

  Gets the binary 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

  See 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 declaring Class for the method represented by this stack frame.

  Returns:

  the declaring Class of the method represented by this stack frame

  Throws:

  UnsupportedOperationException - if this StackWalker is not configured with Option.RETAIN_CLASS_REFERENCE.

• getMethodType

  default MethodType getMethodType()

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

  Implementation Requirements:

  The default implementation throws UnsupportedOperationException.

  Returns:

  the MethodType for this stack frame

  Throws:

  UnsupportedOperationException - if this StackWalker is not configured with Option.RETAIN_CLASS_REFERENCE.

  Since:

  10

• getDescriptor

  default String getDescriptor()

  Returns the descriptor of the method represented by this stack frame as defined by The Java Virtual Machine Specification.

  Implementation Requirements:

• getByteCodeIndex

  int getByteCodeIndex()

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

  See Java Virtual Machine Specification:

  4.7.3 The Code Attribute
  

• getFileName

  String getFileName()

  Returns the name of the source file containing the execution point represented by this stack frame. Generally, this corresponds to the SourceFile attribute of the relevant class file as defined by The 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, or null if this information is unavailable.

  See Java Virtual Machine Specification:

  4.7.10 The SourceFile 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 the LineNumberTable attribute of the relevant class file as defined by The 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.

  See Java Virtual Machine Specification:

  4.7.12 The LineNumberTable Attribute
  

• isNativeMethod

  boolean isNativeMethod()

  Returns true 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 a StackTraceElement for this stack frame.

  Returns:

  StackTraceElement for this stack frame.
