Function Documentation

◆ qgsCalloc()

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.

Parameters

nmemb	number of elements
size	size of element in bytes

Definition at line 134 of file qgis.cpp.

◆ qgsFree()

void qgsFree ( void * ptr )

Frees the memory space pointed to by ptr.

Works like C free().

Parameters

ptr	pointer to memory space

Definition at line 149 of file qgis.cpp.

◆ qgsMalloc()

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.

Parameters

size	size in bytes

Definition at line 119 of file qgis.cpp.

◆ qgsPermissiveToDouble()

double qgsPermissiveToDouble	(	QString	string,
		bool &	ok
	)

Converts a string to a double in a permissive way, e.g., allowing for incorrect numbers of digits between thousand separators.

Parameters

string	string to convert
ok	will be set to `true` if conversion was successful

Returns: string converted to double if possible

See also: permissiveToInt

Since: QGIS 2.9

Definition at line 98 of file qgis.cpp.

◆ qgsPermissiveToInt()

int qgsPermissiveToInt	(	QString	string,
		bool &	ok
	)

Converts a string to an integer in a permissive way, e.g., allowing for incorrect numbers of digits between thousand separators.

Parameters

string	string to convert
ok	will be set to `true` if conversion was successful

Returns: string converted to int if possible

See also: permissiveToDouble

Since: QGIS 2.9

Definition at line 105 of file qgis.cpp.

◆ qgsPermissiveToLongLong()

qlonglong qgsPermissiveToLongLong	(	QString	string,
		bool &	ok
	)

Converts a string to an qlonglong in a permissive way, e.g., allowing for incorrect numbers of digits between thousand separators.

Parameters

string	string to convert
ok	will be set to `true` if conversion was successful

Returns: string converted to int if possible

See also: permissiveToInt

Since: QGIS 3.4

Definition at line 112 of file qgis.cpp.

◆ qgsVariantEqual()

bool qgsVariantEqual	(	const QVariant &	lhs,
		const QVariant &	rhs
	)

Compares two QVariant values and returns whether they are equal, two NULL values are always treated as equal and 0 is not treated as equal with NULL.

Parameters

lhs	first value
rhs	second value

Returns: true if values are equal

Definition at line 298 of file qgis.cpp.

◆ qgsVariantGreaterThan()

bool qgsVariantGreaterThan	(	const QVariant &	lhs,
		const QVariant &	rhs
	)

Compares two QVariant values and returns whether the first is greater than the second.

Useful for sorting lists of variants, correctly handling sorting of the various QVariant data types (such as strings, numeric values, dates and times)

See also: qgsVariantLessThan()

Definition at line 222 of file qgis.cpp.

◆ qgsVariantLessThan()

bool qgsVariantLessThan	(	const QVariant &	lhs,
		const QVariant &	rhs
	)

Compares two QVariant values and returns whether the first is less than the second.

Useful for sorting lists of variants, correctly handling sorting of the various QVariant data types (such as strings, numeric values, dates and times)

Invalid < NULL < Values

See also: qgsVariantGreaterThan()

Definition at line 154 of file qgis.cpp.

◆ qgsVsiPrefix()

QString qgsVsiPrefix ( const QString & path )

Definition at line 227 of file qgis.cpp.
