Constructor & Destructor Documentation

apache::geode::client::CacheableUndefined::CacheableUndefined ( )

inlineprotected

Constructor, used for deserialization.

Member Function Documentation

virtual int32_t apache::geode::client::CacheableUndefined::classId ( ) const

virtual

Return the classId of the instance being serialized.

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

Implements apache::geode::client::Serializable.

static CacheableUndefinedPtr apache::geode::client::CacheableUndefined::create ( )

inlinestatic

Factory method for creating the default instance of CacheableUndefined.

template<class PRIM >

static SerializablePtr apache::geode::client::Serializable::create ( const PRIM value )

inlinestaticinherited

Factory method that creates the Serializable object that matches the type of value.

For customer defined derivations of Serializable, the method apache::geode::client::createValue may be overloaded. For pointer types (e.g. char*) the method apache::geode::client::createValueArr may be overloaded.

static Serializable* apache::geode::client::CacheableUndefined::createDeserializable ( )

inlinestatic

creation function for undefined query result

virtual int8_t apache::geode::client::CacheableUndefined::DSFID ( ) const

virtual

Return the data serialization fixed ID size type for internal use.

Since: GFE 5.7

Reimplemented from apache::geode::client::Serializable.

virtual Serializable* apache::geode::client::CacheableUndefined::fromData ( DataInput & input )

virtual

deserialize this object

Implements apache::geode::client::Serializable.

virtual uint32_t apache::geode::client::CacheableUndefined::objectSize ( ) const

virtual

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. Note that you must implement this only if you use the HeapLRU feature.

Reimplemented from apache::geode::client::Serializable.

void apache::geode::client::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t apache::geode::client::SharedBase::refCount ( )

inlineinherited

Returns: the reference count

static void apache::geode::client::Serializable::registerPdxSerializer ( PdxSerializerPtr pdxSerializer )

staticinherited

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

See also: PdxSerializer

static void apache::geode::client::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 apache::geode::client::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 apache::geode::client::SharedBase::releaseSB ( ) const

inherited

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

virtual void apache::geode::client::CacheableUndefined::toData ( DataOutput & output ) const

virtual

serialize this object

Implements apache::geode::client::Serializable.

virtual CacheableStringPtr apache::geode::client::Serializable::toString ( ) const

virtualinherited

Display this object as 'string', which depends on the implementation in the subclasses.

The default implementation renders the classname.

The return value may be a temporary, so the caller has to ensure that the SharedPtr count does not go down to zero by storing the result in a variable or otherwise.

Reimplemented in apache::geode::client::PdxInstance, apache::geode::client::CacheableString, apache::geode::client::CacheableDate, apache::geode::client::CacheableEnum, and apache::geode::client::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >.

virtual int8_t apache::geode::client::CacheableUndefined::typeId ( ) const

virtual

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 apache::geode::client::Serializable.
