Typedef Documentation

LazyDataset_t

typedef struct _LazyDataset_t LazyDataset_t

Defines a LazyNodeListReader instance.

Function Documentation

LazyDataset_get()

RaveData2D_t * LazyDataset_get

(

LazyDataset_t *

self

)

Load the data upon request.

LazyDataset_init()

int LazyDataset_init	(	LazyDataset_t *	self,
		LazyNodeListReader_t *	reader,
		const char *	nodename )

Initializes this object with the reader and the name of the node to fetch.

The nodename must exist within the available names in the reader otherwise initialization will fail.

Parameters

[in]	self	- self
[in]	reader	- the node list reader
[in]	nodename	- the name of the node

Returns

1 on success otherwise 0
