Detailed Description

This class enables you to use long identifiers stored as 64 bits.

Library: ilvmaps

A long identifier is used to identify a FRID record. These identifiers are stored as 64 bits (or two integers). If both integers are equal to 0, the identifier is considered as null.

Constructor & Destructor Documentation

IlvS57AssocId::IlvS57AssocId	(	IlInt	h = 0,
		IlInt	l = 0
	)

Initializes the values of both parts of the identifier.

Parameters

h	The higher(left) part of the 64 bit identifier.
l	The lower(right) part of the 64 bit identifier.

IlvS57AssocId::IlvS57AssocId

(

const IlvS57AssocId &

src

)

Initializes an identifier with the value of another identifier.

Parameters

src	The original identifier.

Member Function Documentation

const char* IlvS57AssocId::getValue

(

)

Returns the identifier as a string.

Returns

The identifier as a string. Do not delete the string because it is stored in a static buffer. If you call this function twice, the first string value is erased by the second string value.

IlBoolean IlvS57AssocId::isNull

(

)

const

Returns IlTrue if the identifier is null.

Returns

IlTrue if the identifier is null. An identifier is null if the higher(left) and lower(right) parts are equal to 0.

int IlvS57AssocId::operator==

(

const IlvS57AssocId &

obj

)

const

The equality operator.

Parameters

obj	The second identifier.

Returns

0 if the identifiers are different otherwise returns 1.

void IlvS57AssocId::set	(	IlInt	h,
		IlInt	l
	)

Sets the values of both parts of the identifier.

Parameters

h	The higher(left) part of the 64 bit identifier.
l	The lower(right) part of the 64 bit identifier.
