                                throws CorruptDataException

Prints all the j9object fields

Parameters:

out - output stream

tabLevel - indicates the starting tab level

localClazz - the class of the j9object

dataStart - start location of the j9object

localObject - pointer to the j9object

address - address of the object being printed

printJ9ObjectFields

public static void printJ9ObjectFields(PrintStream out,
 int tabLevel,
 com.ibm.j9ddr.vm29.pointer.generated.J9ClassPointer localClazz,
 U8Pointer dataStart,
 com.ibm.j9ddr.vm29.pointer.generated.J9ObjectPointer localObject,
 long address,
 String[] nestingHierarchy,
 boolean showNestedFields)
                                throws CorruptDataException

Prints all the j9object fields

Parameters:

out - The output stream

tabLevel - Indicates the starting tab level

localClazz - The class of the j9object

dataStart - The start location of the object. If printing a nested type this is the effect address of the nested type

localObject - The pointer to the j9object

address - The address of the object being printed. If printing a nested type this is the address of the top level container

nestingHierarchy - This is an array of field names that specifies which nested type contained in the top level container to be printed The first array element is the name of a nested field in the top level container. The second array element is the name of a nested field that is a member of the of the nested field specified in the first array element. And so on...

showNestedFields - Specifies if the entire structure of nested fields should be outputted

Throws:

CorruptDataException
