template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual int32_t gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::classId ( ) const

inlinevirtualinherited

Return the classId of the instance being serialized.

This is used by deserialization to determine what instance type to create and deserialize into.

Implements gemfire::Serializable.

template<class PRIM >

static CacheableKeyPtr gemfire::CacheableKey::create ( const PRIM value )

inlinestaticinherited

Factory method that creates the key type that matches the type of value.

For customer defined derivations of CacheableKey, the method gemfire::createKey may be overloaded. For pointer types (e.g. char*) the method gemfire::createKeyArr may be overloaded.

static CacheableDoublePtr gemfire::CacheableDouble::create ( )

inlinestatic

Factory function to create a new default instance.

static CacheableDoublePtr gemfire::CacheableDouble::create ( const double value )

inlinestatic

Factory function to create an instance with the given value.

static Serializable* gemfire::CacheableDouble::createDeserializable ( )

inlinestatic

Factory function registered with serialization registry.

virtual int8_t gemfire::Serializable::DSFID ( ) const

virtualinherited

return the Data Serialization Fixed ID type.

This is used to determine what instance type to create and deserialize into.

Note that this should not be overridden by custom implementations and is reserved only for builtin types.

Reimplemented in gemfire::Struct, and gemfire::CacheableUndefined.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual Serializable* gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::fromData ( DataInput & input )

inlinevirtualinherited

Deserialize this object from given DataInput.

Implements gemfire::Serializable.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual uint32_t gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::hashcode ( ) const

inlinevirtualinherited

Return the hashcode for this key.

Implements gemfire::CacheableKey.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual int32_t gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::logString	(	char *	buffer,
		int32_t	maxLength
	)		const

inlinevirtualinherited

Copy the string form of the object into a char* buffer for logging purposes.

Reimplemented from gemfire::CacheableKey.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual uint32_t gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::objectSize ( ) const

inlinevirtualinherited

Return the size in bytes of the instance being serialized.

This is used to determine whether the cache is using up more physical memory than it has been configured to use. The method can return zero if the user does not require the ability to control cache memory utilization.

Reimplemented from gemfire::Serializable.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual bool gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::operator== ( const CacheableKey & other ) const

inlinevirtualinherited

Return true if this key matches other.

Implements gemfire::CacheableKey.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

bool gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::operator== ( const TObj other ) const

inlineinherited

Return true if this key matches other key value.

void gemfire::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t gemfire::SharedBase::refCount ( )

inlineinherited

Returns: the reference count

static void gemfire::Serializable::registerPdxSerializer ( PdxSerializerPtr pdxSerializer )

staticinherited

Register the PDX serializer which can handle serialization for instances of user domain classes.

See also: PdxSerializer

static void gemfire::Serializable::registerPdxType ( TypeFactoryMethodPdx creationFunction )

staticinherited

register an Pdx instance factory method for a given type.

Exceptions

IllegalStateException if the typeName has already been registered, or there is an error in registering the type; check errno for more information in the latter case.

static void gemfire::Serializable::registerType ( TypeFactoryMethod creationFunction )

staticinherited

register an instance factory method for a given type.

During registration the factory will be invoked to extract the typeId to associate with this function.

Exceptions

IllegalStateException if the typeId has already been registered, or there is an error in registering the type; check errno for more information in the latter case.

void gemfire::SharedBase::releaseSB ( ) const

inherited

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual void gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::toData ( DataOutput & output ) const

inlinevirtualinherited

Serialize this object to given DataOutput.

Implements gemfire::Serializable.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual CacheableStringPtr gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::toString ( ) const

inlinevirtualinherited

Return a string representation of the object.

Reimplemented from gemfire::Serializable.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

virtual int8_t gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::typeId ( ) const

inlinevirtualinherited

Return the typeId byte of the instance being serialized.

This is used by deserialization to determine what instance type to create and deserialize into.

Reimplemented from gemfire::Serializable.

template<typename TObj , int8_t TYPEID, const char * TYPENAME, const char * SPRINTFSYM, int32_t STRSIZE>

TObj gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >::value ( ) const

inlineinherited

Gets the contained value.
