Enum Constant Details

HEAP

public static final ResourceType.Core HEAP

Heap: not persistable, serialization not required.

OFFHEAP

public static final ResourceType.Core OFFHEAP

OffHeap: not persistable, serialization required.

DISK

public static final ResourceType.Core DISK

Disk: persistable, serialization required.

Field Details

persistable

private final boolean persistable

requiresSerialization

private final boolean requiresSerialization

tierHeight

private final int tierHeight

Constructor Details

Core

private Core(boolean persistable,
 boolean requiresSerialization,
 int tierHeight)

Method Details

values

public static ResourceType.Core[] values()

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

Returns:

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

valueOf

public static ResourceType.Core 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

getResourcePoolClass

public Class<SizedResourcePool> getResourcePoolClass()

Description copied from interface: ResourceType

Gets the ResourcePool type associated with this ResourceType.

Specified by:

getResourcePoolClass in interface ResourceType<SizedResourcePool>

Returns:

the ResourcePool type associated with this type

isPersistable

public boolean isPersistable()

Description copied from interface: ResourceType

Indicates whether this ResourceType supports persistence.

Persistence in this context means that a ResourcePool of this ResourceType can be configured so that data stored in it will survive a JVM restart.

Specified by:

isPersistable in interface ResourceType<SizedResourcePool>

Returns:

true if it supports persistence, false otherwise

requiresSerialization

public boolean requiresSerialization()

Description copied from interface: ResourceType

Indicates whether this ResourceType requires serialization support.

Specified by:

requiresSerialization in interface ResourceType<SizedResourcePool>

Returns:

true if serializers are required, false otherwise

getTierHeight

public int getTierHeight()

Description copied from interface: ResourceType

Indicates the level this resource sits in the tiering system.

Higher means resource is faster and less abundant, lower means resource is slower but potentially larger.

Specified by:

getTierHeight in interface ResourceType<SizedResourcePool>

Returns:

the resource tier height

toString

public String toString()

Overrides:

toString in class Enum<ResourceType.Core>
