Method Detail

getReader

protected StackTraceReader getReader()

Overrides:

getReader in class ReaderProxy

isLoaded

public boolean isLoaded()

Specified by:

isLoaded in interface StackTraceReader

Overrides:

isLoaded in class StackTraceReader.StackTraceReaderDelegate

getThreadId

public long getThreadId()

Description copied from interface: StackTraceReader

File may include extra event besides thread dumps. E.g. memory dynamics or OS metrics could be included for further analysis.

Extra events are seconds class citizens so some readers may filter them out.
