Factory method for creating an instance of CacheableObjectArray with given size.

creation function for java Object[]

virtual int8_t gemfire::Serializable::DSFID (  )  const [virtual, inherited]

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::CacheableUndefined, and gemfire::Struct.

template<class PTR_TYPE>
bool gemfire::VectorT< PTR_TYPE >::empty (  )  const [inline, inherited]

virtual uint32_t gemfire::CacheableObjectArray::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 gemfire::Serializable.

PdxSerializer

static void gemfire::Serializable::registerPdxType ( TypeFactoryMethodPdx  creationFunction  )  [static, inherited]

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  )  [static, inherited]

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<class PTR_TYPE>
void gemfire::VectorT< PTR_TYPE >::reserve ( int32_t  n  )  [inline, inherited]

reallocate a vector to hold n elements.

template<class PTR_TYPE>

const PTR_TYPE &  t = gemfire::NullSharedBase::s_instancePtr 
) [inline, inherited]

inserts or erases elements at the end such that size becomes n.

Not to be confused with reserve which simply allocates the space, resize fills the space with active elements.

return the size of the vector.

template<class PTR_TYPE>
void gemfire::VectorT< PTR_TYPE >::swap ( VectorT< PTR_TYPE > &  other  )  [inline, inherited]

serialize this object

Implements gemfire::Serializable.

virtual CacheableStringPtr gemfire::Serializable::toString (  )  const [virtual, inherited]

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 gemfire::CacheableKeyType< TObj, TYPEID, TYPENAME, SPRINTFSYM, STRSIZE >, gemfire::CacheableDate, gemfire::CacheableEnum, and gemfire::CacheableString.

virtual int8_t gemfire::CacheableObjectArray::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 gemfire::Serializable.
