Method Detail

clear

public abstract void clear()

                          boolean nursery)

Scan through the list of references.

Parameters:

trace - the thread local trace element.

nursery - true if it is safe to only scan new references.

                             boolean nursery)

Iterates over and forward entries in the table.

Parameters:
