Detailed Description

Implement a date object based on epoch of January 1, 1970 00:00:00 GMT that can serve as a distributable key object for caching as well as being a date value.

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>.

◆ CacheableDate() [3/3]

apache::geode::client::CacheableDate::CacheableDate ( const duration &  value)
explicit

Construct from std::chrono::seconds since POSIX epoch.

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.
