Field Summary

Fields

Modifier and Type	Field and Description
static TypeAssertion	WITH_RAW_TYPES When used warnings will be issued where types are configured but not used.

Method Summary

Modifier and Type	Method and Description
default boolean	assertTypeSafety(String sCacheName, CacheMapping cacheMapping) Asserts the type compatibility of a named cache given the CacheMapping that defines the cache.
boolean	assertTypeSafety(String sCacheName, CacheMapping cacheMapping, boolean fLog) Asserts the type compatibility of a named cache given the CacheMapping that defines the cache.
static <K,V> TypeAssertion<K,V>	withoutTypeChecking() Obtains a TypeAssertion that allows NamedCaches to be acquired without type-checking, warnings or log messages.
static TypeAssertion	withRawTypes() Obtains a TypeAssertion that allows NamedCaches to be acquired and assigned to a raw NamedCache reference.
static <K,V> TypeAssertion<K,V>	withTypes(Class<K> clsKey, Class<V> clsValue) Obtains a TypeAssertion that asserts the specified types are configured for a cache.

Field Detail

WITHOUT_TYPE_CHECKING

static final TypeAssertion WITHOUT_TYPE_CHECKING

When used no type checking will occur and no warnings will be generated.

WITH_RAW_TYPES

static final TypeAssertion WITH_RAW_TYPES

When used warnings will be issued where types are configured but not used.

Method Detail

assertTypeSafety

boolean assertTypeSafety(String sCacheName,
                         CacheMapping cacheMapping,
                         boolean fLog)
                  throws IllegalArgumentException

Asserts the type compatibility of a named cache given the CacheMapping that defines the cache.

Parameters:

sCacheName - the name of the cache

cacheMapping - the CacheMapping

fLog - when true, log warning if typing mismatch between CacheMapping configuration and this TypeAssertion; specifically, one uses raw types and the other asserts specific types.

Returns:

false if warning logged about the assertion, true otherwise.

Throws:

IllegalArgumentException - when types used with the TypeAssertion are illegal according to the configuration

assertTypeSafety

default boolean assertTypeSafety(String sCacheName,
                                 CacheMapping cacheMapping)
                          throws IllegalArgumentException

Asserts the type compatibility of a named cache given the CacheMapping that defines the cache.

Parameters:

sCacheName - the name of the cache

cacheMapping - the CacheMapping

Returns:

false if warning logged about the assertion, true otherwise.

Throws:

IllegalArgumentException - when types used with the TypeAssertion are illegal according to the configuration

withTypes

static <K,V> TypeAssertion<K,V> withTypes(Class<K> clsKey,
                                          Class<V> clsValue)

Obtains a TypeAssertion that asserts the specified types are configured for a cache.

Type Parameters:

K - the key type

V - the value type

Parameters:

clsKey - the desired key type

clsValue - the desired value type

Returns:

a TypeAssertion

withRawTypes

@Options.Default
static TypeAssertion withRawTypes()

Obtains a TypeAssertion that allows NamedCaches to be acquired and assigned to a raw NamedCache reference. A debug log message will be raised for caches that have been configured with specific types.

Returns:

a TypeAssertion

withoutTypeChecking

static <K,V> TypeAssertion<K,V> withoutTypeChecking()

Obtains a TypeAssertion that allows NamedCaches to be acquired without type-checking, warnings or log messages.

Type Parameters:

K - the key type

V - the value type

Returns:

a TypeAssertion
