Constructor & Destructor Documentation

CacheableDate() [1/3]

apache::geode::client::CacheableDate::CacheableDate ( const time_t  value = 0 )

explicit

Constructor, used for deserialization.

CacheableDate() [2/3]

apache::geode::client::CacheableDate::CacheableDate ( const time_point &  value )

explicit

Construct from std::chrono::time_point<std::chrono::system_clock>.

Member Function Documentation

create() [1/2]

static std::shared_ptr<CacheableDate> apache::geode::client::CacheableDate::create ( )

inlinestatic

Factory method for creating an instance of CacheableDate.

create() [2/2]

template<class _T >

static std::shared_ptr<CacheableKey> apache::geode::client::CacheableKey::create ( _T  value )

staticinherited

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

For user defined derivations of CacheableKey, the method apache::geode::client::CacheableKey::create may be overloaded.

createDeserializable()

static std::shared_ptr<Serializable> apache::geode::client::CacheableDate::createDeserializable ( )

static

creation function for dates.

hashcode()

virtual int32_t apache::geode::client::CacheableDate::hashcode ( ) const

overridevirtual

Returns a hash code value for this object.

The result is the exclusive OR of the two halves of the primitive long value returned by the milliseconds() method.

Returns

the hashcode for this object.

Implements apache::geode::client::CacheableKey.

milliseconds()

virtual int64_t apache::geode::client::CacheableDate::milliseconds ( ) const

virtual

Returns

milliseconds elapsed since January 1, 1970, 00:00:00 GMT.

objectSize()

virtual size_t apache::geode::client::CacheableDate::objectSize ( ) const

inlineoverridevirtual

Returns

the size of the object in bytes

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

operator==()

virtual bool apache::geode::client::CacheableDate::operator== ( const CacheableKey &  other ) const

overridevirtual

Returns

true if this key matches other.

Implements apache::geode::client::CacheableKey.

toString()

std::string apache::geode::client::CacheableDate::toString ( ) const

overridevirtual

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

The default implementation renders the classname.

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