addProperty

public void addProperty(Object key,
                        Object value)

Parameters:

key -

value -

getStackFrames

public Iterator getStackFrames()
                        throws DataUnavailable

Not available in javacore

Specified by:

getStackFrames in interface ImageThread

Returns:

an iterator to walk the native stack frames in order from top-of-stack (that is, the most recent frame) to bottom-of-stack. Throws DataUnavailable if native stack frames are not available on this platform.

Throws:

DataUnavailable - If native stack frames are not available on this platform

addImageStackFrame

public void addImageStackFrame(ImageStackFrame stackFrame)

NOT in DTFJ

Parameters:

stackFrame -

addImageStackSection

public void addImageStackSection(ImageSection stackSection)

NOT in DTFJ Add a stack section for this thread. Duplicates are not removed. Do NOT use this outside the building process.

Parameters:

stackSection -

getInternalID

public ImagePointer getInternalID()

NON-DTFJ. Used internally as it bypasses the exception, since due to internal implementation, an exception thrown when the id is not set does not necessarily mean an internal building error. Do NOT use this outside the building process.

setSystemThreadID

public void setSystemThreadID(ImagePointer systemThreadID)

NON-DTFJ. For building purposes only. Don't use as part of DTFJ.

Parameters:

systemThreadID -

getSystemThreadID

public ImagePointer getSystemThreadID()

NON-DTFJ. For building purposes only. Don't use as part of DTFJ.

Returns:

system thread id or null if not set.

addRegister

public void addRegister(ImageRegister reg)

NOT in DTFJ

Parameters:

reg - register
