Functions | |
void * | qgsMalloc (size_t size) |
Allocates size bytes and returns a pointer to the allocated memory. | |
void * | qgsCalloc (size_t nmemb, size_t size) |
Allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. | |
void | qgsFree (void *ptr) |
Frees the memory space pointed to by ptr. | |
bool | qgsVariantLessThan (const QVariant &lhs, const QVariant &rhs) |
bool | qgsVariantGreaterThan (const QVariant &lhs, const QVariant &rhs) |
QString | qgsVsiPrefix (QString path) |
Variables | |
const CORE_EXPORT QString | GEOPROJ4 = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" |
PROJ4 string that represents a geographic coord sys. | |
const CORE_EXPORT QString | GEOWKT = " AUTHORITY[\"EPSG\",4326]]" |
Wkt string that represents a geographic coord sys. | |
const CORE_EXPORT QString | PROJECT_SCALES = "1:10000,1:5000,1:2500,1:1000,1:500" |
const CORE_EXPORT QString | GEO_EPSG_CRS_AUTHID = "EPSG:4326" |

void* qgsCalloc | ( | size_t | nmemb, |
size_t | size | ||
) |
Allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory.
Works like C calloc() but prints debug message by QgsLogger if allocation fails.
nmemb | number of elements |
size | size of element in bytes |
void qgsFree | ( | void * | ptr | ) |
Frees the memory space pointed to by ptr.
Works like C free().
ptr | pointer to memory space |
void* qgsMalloc | ( | size_t | size | ) |
Allocates size bytes and returns a pointer to the allocated memory.
Works like C malloc() but prints debug message by QgsLogger if allocation fails.
size | size in bytes |
bool qgsVariantGreaterThan | ( | const QVariant & | lhs, |
const QVariant & | rhs | ||
) |
bool qgsVariantLessThan | ( | const QVariant & | lhs, |
const QVariant & | rhs | ||
) |
QString qgsVsiPrefix | ( | QString | path | ) |
const CORE_EXPORT QString GEO_EPSG_CRS_AUTHID = "EPSG:4326" |
Geographic coord sys from EPSG authority.
const CORE_EXPORT QString GEO_NONE = "NONE" |
Constant that holds the string representation for "No ellips/No CRS".
const CORE_EXPORT QString GEOPROJ4 = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" |
PROJ4 string that represents a geographic coord sys.
