Description

Abstract base class for data classes representing one dimensional arrays.

Functions

b_vector_get_len ()

unsigned int
b_vector_get_len (BVector *vec);

Get the number of values in vec and caches it.

Parameters

vec

BVector

Returns

the length

b_vector_get_values ()

const double *
b_vector_get_values (BVector *vec);

Get the full array of values of vec and cache them.

Parameters

vec

BVector

Returns

an array.

b_vector_get_value ()

double
b_vector_get_value (BVector *vec,
                    unsigned int i);

Get a value in vec .

Parameters

vec	BVector
i	index

Returns

the value

b_vector_get_str ()

char *
b_vector_get_str (BVector *vec,
                  unsigned int i,
                  const gchar *format);

Get a string representation of an element in vec .

Parameters

vec	BVector
i	index
format	a format string

Returns

the string. The caller is responsible for freeing it.

b_vector_get_minmax ()

void
b_vector_get_minmax (BVector *vec,
                     double *min,
                     double *max);

Get the minimum and maximum values in vec and cache them.

Parameters

vec	BVector
min	return location for minimum value, or `NULL` .	[out][nullable]
max	return location for maximum value, or `NULL` .	[out][nullable]

b_vector_is_varying_uniformly ()

gboolean
b_vector_is_varying_uniformly (BVector *data);

Returns whether elements of data only increase or only decrease.

Parameters

data

BVector

Returns

TRUE if elements of data strictly increase or decrease.

b_vector_replace_cache ()

double *
b_vector_replace_cache (BVector *vec,
                        unsigned int len);

Frees old cache and replaces it with newly allocated memory, of length len . Used by subclasses of BVector.

Parameters

vec	BVector
len	new length of cache

Returns

Pointer to the new cache.

Types and Values

struct BVectorClass

struct BVectorClass {
	BDataClass base;

	unsigned int (*load_len) (BVector * vec);
	double *(*load_values) (BVector * vec);
	double (*get_value) (BVector * vec, unsigned int i);
	double *(*replace_cache) (BVector *vec, unsigned int len);
};

Class for BVector.

Members

BDataClass `base`;	base class.
`load_len` ()	loads the vector length and returns it.
`load_values` ()	loads the values and returns them.
`get_value` ()	gets a value.
`replace_cache` ()	replaces array cache

BVector

typedef struct _BVector BVector;

Object representing a one-dimensional array of numbers.
