public class StackFrame
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<StackFrame>

Method Detail

getInjectedException

public InjectableException getInjectedException()

Returns:

the InjectableException that was injected

getFrameNumber

public long getFrameNumber()

Frame numbers are used to compare StackFrames that have the same pushTime.

Returns:

the frameNumber

getMethodSignature

public java.lang.String getMethodSignature()

Returns:

Signature of the method called. This is never null or empty.

getInjectableExceptions

public int[] getInjectableExceptions()

Returns:

The exception IDs that have been explicitly identified as valid to be injected in this method. An empty array indicates that none have been explicitely identified. Any exception can always be injected at any point regardless of whether it is listed here or not.

getException

public java.lang.String getException()

Returns:

The exception thrown by the method. Null if the method has not returned or returned without throwing an exception.

getStackLevel

public int getStackLevel()

Returns:

The level indicates how deep in the stack the method is. If method A calls B calls C then B calld D the levels will be as follows: Method A = 0, B = 1, C = 2, D = 2

getTraceIndex

public int getTraceIndex()

Returns:

The index of this frame in the StackTrace

getPushTime

public java.util.Date getPushTime()

Returns:

The time this frame was pushed onto the StackTrace

getPopTime

public java.util.Date getPopTime()

Returns:

The time this frame was popped off of the StackTrace

getDuration

public long getDuration()

Returns:

The duration of the method call in milliseconds

compareTo

public int compareTo(StackFrame that)

Sorts based on pushTime then frameNumber
