(List<Object> dtfjcontexts, PrintStream out) Construct DDR from DTFJ contexts, this prevents both the DTFJ view such as jdmpview from scanning a core file, followed by a second scan by DDR interactive. -

Constructor Details

DDRInteractive
Construct DDR from J9DDRImage, ICore or IProcess- Parameters:
obj
- Core file.out
- result output stream.- Throws:
Exception

DDRInteractive
- Throws:
Exception
-
DDRInteractive
Construct DDR from DTFJ contexts, this prevents both the DTFJ view such as jdmpview from scanning a core file, followed by a second scan by DDR interactive. It also ensures that a tool can know which contexts point to the same VM. Uses reflection to avoid a binding to the DTFJ jars which allows DDR to be invoked independently- Parameters:
out
- result output stream.obj
-- Throws:
Exception
-
DDRInteractive
Start DDR. Read command from standard input.- Parameters:
path
- path to core file.out
- result output stream.- Throws:
Exception
-
DDRInteractive
Start DDR- Parameters:
path
- core file location on disk.commandReader
- user input.out
- result output stream.- Throws:
Exception

getCommandNames
-
getCurrentContext
Get the current context that is being operated on. This is used by external applications such as Eclipse which are providing their own command parsers- Returns:
- the current context
-
startDDR
-
setInputStream
Used by external clients to set the input stream.- Parameters:
in
- the new stream to read commands from
-
processLine

getPath
This function returns the path DDR interactive was invoked against. This allows commands to obtain the file name. ( A single file could contain multiple address spaces/processes so this cannot be usefully stored on IProcess or IContext. ) External tools may create more than one instance of DDRInteractive at the same time. This is a static property so allow it to be changed by external tools. The path can set at startup or via the com.ibm.j9ddr.tools.ddrinteractive.filepath system property- Returns:
- the path to the file DDRInteractive was launched against or null if a path wasn't specified.
