typedef struct JKVIterator JKVIterator

Function Documentation

j_kv_iterator_free()

void j_kv_iterator_free

(

JKVIterator *

iterator

)

Frees the memory allocated by the JKVIterator.

Parameters

iterator

A JKVIterator.

j_kv_iterator_get()

gchar const* j_kv_iterator_get	(	JKVIterator *	iterator,
		gconstpointer *	value,
		guint32 *	len
	)

Returns the current collection.

Parameters

iterator	A store iterator.
value	A pointer to be set to the current value.
len	Will be set to the length of the current value.

Returns

The current key.

j_kv_iterator_new()

G_END_DECLS G_BEGIN_DECLS JKVIterator* j_kv_iterator_new	(	gchar const *	namespace,
		gchar const *	prefix
	)

Creates a new JKVIterator.

Parameters

namespace	JKV namespace to iterate over.
prefix	Prefix of keys to iterate over. Set to NULL to iterate over all KVs.

Returns

A new JKVIterator.

j_kv_iterator_new_for_index()

JKVIterator* j_kv_iterator_new_for_index	(	guint32	index,
		gchar const *	namespace,
		gchar const *	prefix
	)

Creates a new JKVIterator on a specific KV server.

Parameters

index	Server to query.
namespace	JKV namespace to iterate over.
prefix	Prefix of keys to iterate over. Set to NULL to iterate over all KVs.

Returns

A new JKVIterator.

j_kv_iterator_next()

gboolean j_kv_iterator_next

(

JKVIterator *

iterator

)

Checks whether another collection is available.

Parameters

iterator

A store iterator.

Returns

TRUE on success, FALSE if the end of the store is reached.
