scanObject

public static void scanObject(int code,
                              int id,
                              Object object,
                              TransitiveClosure trace)

Hand-inlined scanning of objects. The cases of the conditional are ordered in descending frequency of patterns. This entry point falls back to specialized scanning if it is enabled.

Parameters:

code - the code to use for specialized scanning. This determines the pattern that will be used.

id - the id of the specialized scan method

object - the object to scan

trace - the closure to use

scanObject

public static void scanObject(int code,
                              Object object,
                              TransitiveClosure trace)

Hand-inlined scanning of objects. The cases of the conditional are ordered in descending frequency of patterns.

This entry point does not fall back to specialized scanning.

Parameters:

code - the code to use for specialized scanning. This determines the pattern that will be used.

object - the object to scan

trace - the closure to use

scanObject

private static void scanObject(int code,
                               int id,
                               Object object,
                               TransitiveClosure trace,
                               boolean specialize)
