Parameters:

cls - The class name

method - The method name

file - The file name

line - The line number

Method Detail

equals

public boolean equals(Object obj)

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

Overrides:

equals in class Object

Parameters:

obj - the object to compare to

Returns:
