Constructor & Destructor Documentation

Guid()

ignite::Guid::Guid	(	int64_t	most,
		int64_t	least
	)

Constructor.

Parameters

most	Most significant bits.
least	Least significant bits.

Member Function Documentation

Compare()

int64_t ignite::Guid::Compare

(

const Guid &

other

)

const

Compare to another value.

Parameters

other

Instance to compare to.

Returns

Zero if equals, negative number if less and positive if more.

GetHashCode()

int32_t ignite::Guid::GetHashCode

(

)

const

Get hash code of this instance (used in serialization).

Returns

Hash code.

GetLeastSignificantBits()

int64_t ignite::Guid::GetLeastSignificantBits

(

)

const

Returns the least significant 64 bits of this instance.

Returns

The least significant 64 bits of this instance.

GetMostSignificantBits()

int64_t ignite::Guid::GetMostSignificantBits

(

)

const

Returns the most significant 64 bits of this instance.

Returns

The most significant 64 bits of this instance.

GetVariant()

int32_t ignite::Guid::GetVariant

(

)

const

The variant number associated with this instance.

The variant number describes the layout of the Guid.

The variant number has the following meaning: 0 Reserved for NCS backward compatibility; 2 IETF RFC 4122 (Leach-Salz), used by this class; 6 Reserved, Microsoft Corporation backward compatibility; 7 Reserved for future definition.

Returns

The variant number of this instance.

GetVersion()

int32_t ignite::Guid::GetVersion

(

)

const

The version number associated with this instance.

The version number describes how this Guid was generated.

The version number has the following meaning: 1 Time-based UUID; 2 DCE security UUID; 3 Name-based UUID; 4 Randomly generated UUID.

Returns

The version number of this instance.
