All Implemented Interfaces:

ISnapshotContext

public class CFFrameProcessor
extends FrameProcessor

We want to map the variables from the Java variables to the CF variables. So we have a custom processor for CF that lets us perform this mapping.

public CFFrameProcessor(Settings settings,
                        IEvaluator evaluator,
                        Map<String,Object> variables,

Method Detail

getMethodName

protected String getMethodName(StackTraceElement stackTraceElement,
                               Map<String,Object> variables,
                               int frameIndex)

Description copied from class: FrameCollector

Get the method name from the stack frame.

Overrides:

getMethodName in class FrameCollector

Parameters:

stackTraceElement - the stack frame to process

variables - the variables for the frame

frameIndex - the frame index

Returns:

the name of the method

isAppFrame

protected boolean isAppFrame(StackTraceElement stackTraceElement)

Description copied from class: FrameCollector

An app frame is defined via the settings ISettings.APP_FRAMES_INCLUDES and ISettings.APP_FRAMES_EXCLUDES. This gives a way to tell deep that the frame is part of your app and not part of the framework. This is primarily used as a way to filter frames in the UI.

Overrides:

isAppFrame in class FrameCollector

Parameters:

stackTraceElement - the stack frame to process

Returns:

true if the class name is in the included packages, and not in the excluded packages, else false.

selectVariables

protected Map<String,Object> selectVariables(int frameIndex)

Description copied from class: FrameCollector

Select from the available captured variables the variables we want to process for this frame. This is mainly here to allow for an easy way for CF to map the variables from their capture Java types to the expected CF types.

Overrides:

selectVariables in class FrameCollector

Parameters:

frameIndex - the index of the frame we are processing

Returns:

the variables available at this frame
