StackTraceElement

class StackTraceElement : Serializable
kotlin.Any
   ↳ java.lang.StackTraceElement

An element in a stack trace, as returned by java.lang.Throwable#getStackTrace(). Each element represents a single stack frame. All stack frames except for the one at the top of the stack represent a method invocation. The frame at the top of the stack represents the execution point at which the stack trace was generated. Typically, this is the point at which the throwable corresponding to the stack trace was created.

Summary

Public constructors
StackTraceElement(declaringClass: String!, methodName: String!, fileName: String!, lineNumber: Int)

Creates a stack trace element representing the specified execution point.

Public methods
Boolean
equals(other: Any?)

Returns true if the specified object is another StackTraceElement instance representing the same execution point as this instance.

String!

Returns the fully qualified name of the class containing the execution point represented by this stack trace element.

String!

Returns the name of the source file containing the execution point represented by this stack trace element.

Int

Returns the line number of the source line containing the execution point represented by this stack trace element.

String!

Returns the name of the method containing the execution point represented by this stack trace element.

Int

Returns a hash code value for this stack trace element.

Boolean

Returns true if the method containing the execution point represented by this stack trace element is a native method.

String

Returns a string representation of this stack trace element.

StackTraceElement

Added in API level 1
StackTraceElement(
    declaringClass: String!,
    methodName: String!,
    fileName: String!,
    lineNumber: Int)

Creates a stack trace element representing the specified execution point.

Parameters
declaringClass String!: the fully qualified name of the class containing the execution point represented by the stack trace element
methodName String!: the name of the method containing the execution point represented by the stack trace element
fileName String!: the name of the file containing the execution point represented by the stack trace element, or null if this information is unavailable
lineNumber Int: the line number of the source line containing the execution point represented by this stack trace element, or a negative number if this information is unavailable. A value of -2 indicates that the method containing the execution point is a native method
Exceptions
java.lang.NullPointerException if declaringClass or methodName is null

Public methods

equals

Added in API level 1
fun equals(other: Any?): Boolean

Returns true if the specified object is another StackTraceElement instance representing the same execution point as this instance. Two stack trace elements a and b are equal if and only if:

<code>equals(a.getFileName(), b.getFileName()) &amp;&amp;
      a.getLineNumber() == b.getLineNumber()) &amp;&amp;
      equals(a.getClassName(), b.getClassName()) &amp;&amp;
      equals(a.getMethodName(), b.getMethodName())
  </code>
where equals has the semantics of Objects.equals.

Parameters
obj the object to be compared with this stack trace element.
Return
Boolean true if the specified object is another StackTraceElement instance representing the same execution point as this instance.

getClassName

Added in API level 1
fun getClassName(): String!

Returns the fully qualified name of the class containing the execution point represented by this stack trace element.

Return
String! the fully qualified name of the Class containing the execution point represented by this stack trace element.

getFileName

Added in API level 1
fun getFileName(): String!

Returns the name of the source file containing the execution point represented by this stack trace element. Generally, this corresponds to the SourceFile attribute of the relevant class file (as per The Java Virtual Machine Specification, Section 4.7.7). In some systems, the name may refer to some source code unit other than a file, such as an entry in source repository.

Return
String! the name of the file containing the execution point represented by this stack trace element, or null if this information is unavailable.

getLineNumber

Added in API level 1
fun getLineNumber(): Int

Returns the line number of the source line containing the execution point represented by this stack trace element. Generally, this is derived from the LineNumberTable attribute of the relevant class file (as per The Java Virtual Machine Specification, Section 4.7.8).

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

getMethodName

Added in API level 1
fun getMethodName(): String!

Returns the name of the method containing the execution point represented by this stack trace element. If the execution point is contained in an instance or class initializer, this method will return the appropriate special method name, <init> or <clinit>, as per Section 3.9 of The Java Virtual Machine Specification.

Return
String! the name of the method containing the execution point represented by this stack trace element.

hashCode

Added in API level 1
fun hashCode(): Int

Returns a hash code value for this stack trace element.

Return
Int a hash code value for this object.

isNativeMethod

Added in API level 1
fun isNativeMethod(): Boolean

Returns true if the method containing the execution point represented by this stack trace element is a native method.

Return
Boolean true if the method containing the execution point represented by this stack trace element is a native method.

toString

Added in API level 1
fun toString(): String

Returns a string representation of this stack trace element.

Return
String a string representation of the object.
