               AbstractGCEvent.Type type)

Method Detail

add

public void add(GCEvent event)

Overrides:

add in class AbstractGCEvent<GCEvent>

clone

protected Object clone()
                throws CloneNotSupportedException

Overrides:

clone in class AbstractGCEvent<GCEvent>

Throws:

CloneNotSupportedException

cloneAndMerge

public GCEvent cloneAndMerge(AbstractGCEvent<GCEvent> otherEvent)

Overrides:

cloneAndMerge in class AbstractGCEvent<GCEvent>

getYoung

public GCEvent getYoung()

Returns information on young generation. If it was not present in the gc log, but tenured was, it is inferred from there (with -XX:+PrintGCDetails). Otherwise it is null (without -XX:+PrintGCDetails).

Returns:

Information on young generation if possible, null otherwise.

getTenured

public GCEvent getTenured()

Returns information on young generation. If it was not present in the gc log, but tenured was, it is inferred from there (with -XX:+PrintGCDetails). Otherwise it is null (without -XX:+PrintGCDetails).

Returns:

Information on young generation if possible, null otherwise.

getPerm

public GCEvent getPerm()

Returns information on perm generation. If it was not present in the gc log, null will be returned, because the values cannot be inferred.

Returns:

Information on perm generation or null if not present.

toStringBuffer

public void toStringBuffer(StringBuffer sb)

Specified by:

toStringBuffer in class AbstractGCEvent<GCEvent>

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractGCEvent<GCEvent>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractGCEvent<GCEvent>
