Constructor & Destructor Documentation

XrdNetCache()

XrdNetCache::XrdNetCache	(	int	psize = 987,
		int	csize = 1597
	)

Constructor. When allocateing a new hash, two adjacent Fibonocci numbers. The series is simply n[j] = n[j-1] + n[j-2].

Parameters

psize	the correct Fibonocci antecedent to csize.
csize	the initial size of the table.

~XrdNetCache()

XrdNetCache::~XrdNetCache ( )

inline

Destructor. The XrdNetCache object is not designed to be deleted. Doing so will cause memory to be lost.

Member Function Documentation

Add()

void XrdNetCache::Add	(	XrdNetAddrInfo *	hAddr,
		const char *	hName
	)

Add an address-hostname association to the cache. The address must be an INET family address; otherwise it is not added.

Parameters

hAddr	points to the address of the name.
hName	points to the name to be associated with the address.

Expand()

void XrdNetCache::Expand ( )

private

Find()

char * XrdNetCache::Find

(

XrdNetAddrInfo *

hAddr

)

Locate an address-hostname association in the cache.

Parameters

hAddr

points to the address of the name.

Returns

Success: an strdup'd string of the corresponding name. Failure: 0;

GenKey()

int XrdNetCache::GenKey ( anItem &  Item, XrdNetAddrInfo *  hAddr  )

Locate()

anItem * XrdNetCache::Locate ( anItem &  Item )

private

SetKT()

static void XrdNetCache::SetKT ( int  ktval )

inlinestatic

Set the default keep time for entries in the cache during initialization.

Parameters

ktval

the number of seconds to keep an entry in the cache.
