Detailed Description

A vector of attributes.

Mostly equal to QVector<QVariant>.

Definition at line 115 of file qgsfeature.h.

Constructor & Destructor Documentation

QgsAttributes::QgsAttributes ( )
inline

Definition at line 118 of file qgsfeature.h.

QgsAttributes::QgsAttributes ( int  size)
inline

Create a new vector of attributes with the given size.

Parameters
sizeNumber of attributes

Definition at line 126 of file qgsfeature.h.

QgsAttributes::QgsAttributes ( int  size,
const QVariant v 
)
inline

Constructs a vector with an initial size of size elements.

Each element is initialized with value.

Parameters
sizeNumber of elements
vInitial value

Definition at line 134 of file qgsfeature.h.

QgsAttributes::QgsAttributes ( const QVector< QVariant > &  v)
inline

Copies another vector of attributes.

Parameters
vAttributes to copy

Definition at line 142 of file qgsfeature.h.

Member Function Documentation

bool QgsAttributes::operator!= ( const QgsAttributes v) const
inline

Definition at line 168 of file qgsfeature.h.

bool QgsAttributes::operator== ( const QgsAttributes v) const
inline

Compares two vectors of attributes.

They are considered equal if all their members contain the same value and NULL flag. This was introduced because the default Qt implementation of QVariant comparison does not handle NULL values for certain types (like int).

Parameters
vThe attributes to compare
Returns
True if v is equal
