Enum BuiltInCacheMergePolicies

java.lang.Object

java.lang.Enum<BuiltInCacheMergePolicies>

com.hazelcast.cache.BuiltInCacheMergePolicies

All Implemented Interfaces:

Serializable, Comparable<BuiltInCacheMergePolicies>

public enum BuiltInCacheMergePolicies
extends Enum<BuiltInCacheMergePolicies>

Enum that represents all built-in CacheMergePolicy implementations.

Note: When a new built-in CacheMergePolicy is implemented, its definition should be added here also.

Enum Constant Summary

Enum Constants

Enum Constant and Description
HIGHER_HITS Cache merge policy that merges cache entry from source to destination cache if source entry has more hits than the destination one.
LATEST_ACCESS Cache merge policy that merges cache entry from source to destination cache if source entry has been accessed more recently than the destination entry.
PASS_THROUGH Cache merge policy that merges cache entry from source to destination directly.
PUT_IF_ABSENT Cache merge policy that merges cache entry from source to destination if it does not exist in the destination cache.

Enum Constant Detail

PASS_THROUGH

public static final BuiltInCacheMergePolicies PASS_THROUGH

Cache merge policy that merges cache entry from source to destination directly.

PUT_IF_ABSENT

public static final BuiltInCacheMergePolicies PUT_IF_ABSENT

Cache merge policy that merges cache entry from source to destination if it does not exist in the destination cache.

HIGHER_HITS

public static final BuiltInCacheMergePolicies HIGHER_HITS

Cache merge policy that merges cache entry from source to destination cache if source entry has more hits than the destination one.

LATEST_ACCESS

public static final BuiltInCacheMergePolicies LATEST_ACCESS

Cache merge policy that merges cache entry from source to destination cache if source entry has been accessed more recently than the destination entry.

Method Detail

values

public static BuiltInCacheMergePolicies[] 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 (BuiltInCacheMergePolicies c : BuiltInCacheMergePolicies.values())
    System.out.println(c);

Returns:

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

valueOf

public static BuiltInCacheMergePolicies 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

getImplementationClass

public Class<? extends CacheMergePolicy> getImplementationClass()

getImplementationClassName

public String getImplementationClassName()

Gets the name of the implementation class of CacheMergePolicy.

Returns:

the name of the implementation class of CacheMergePolicy.

newInstance

public CacheMergePolicy newInstance()

Create a new instance of CacheMergePolicy.

Returns:

the created instance of CacheMergePolicy

getDefault

public static BuiltInCacheMergePolicies getDefault()

Gets the definition of the default CacheMergePolicy.

Returns:

the definition of the default CacheMergePolicy
