Enum AbstractGCEvent.GcPattern

java.lang.Object

java.lang.Enum<AbstractGCEvent.GcPattern>

com.tagtraum.perf.gcviewer.model.AbstractGCEvent.GcPattern

All Implemented Interfaces:

Serializable, Comparable<AbstractGCEvent.GcPattern>

Enclosing class:

AbstractGCEvent<T extends AbstractGCEvent<T>>

public static enum AbstractGCEvent.GcPattern
extends Enum<AbstractGCEvent.GcPattern>

Patterns of additional information for gc events.

• GC: just the name of the event type
• PAUSE: length of a pause
• DURATION: cycle time of a (usually concurrent) event
• MEMORY: information about heap changes
• REGION: information about number of regions used (only G1 up to now)

Enum Constants

Enum Constant and Description
GC "GC type" (just the name, no additional information)
GC_HEAP_MEMORY_PERCENTAGE "Heap memory type" "memory current"("memory percentage")
GC_MEMORY "GC type": "memory current"("memory total")
GC_MEMORY_PAUSE "GC type": "memory before"->"memory after"("memory total"), "pause"

GC_PAUSE "GC type": "pause"
GC_PAUSE_DURATION "GC type": "pause"/"duration"
GC_REGION "GC type": "# regions before"->"# regions after"[("#total regions")] ("total regions" is optional; needs a region size to calculate memory usage)

Method Detail

values

public static AbstractGCEvent.GcPattern[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AbstractGCEvent.GcPattern c : AbstractGCEvent.GcPattern.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AbstractGCEvent.GcPattern valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
