Member Function Documentation

findMatchingAttributes()

SmallVector< XMLQualifiedNameRef, 1 > donner::svg::components::AttributesComponent::findMatchingAttributes ( const XMLQualifiedNameRef & matcher ) const

inline

Find attributes matching the given name matcher.

Parameters

matcher

Matcher to use to find attributes. If XMLQualifiedNameRef::namespacePrefix is "*", the matcher will match any namespace with the given attribute name.

Returns

A vector of attributes matching the given name matcher.

getAttribute()

std::optional< RcString > donner::svg::components::AttributesComponent::getAttribute ( const XMLQualifiedNameRef & name ) const

inline

Get the value of an attribute, if it exists.

Parameters

name	Name of the attribute to get.

Returns

The value of the attribute, or std::nullopt if the attribute does not exist.

hasAttribute()

bool donner::svg::components::AttributesComponent::hasAttribute ( const XMLQualifiedNameRef & name ) const

inline

Returns true if the element has an attribute with the given name.

Parameters

name	Name of the attribute to check.

Returns

true if the attribute exists, false otherwise.

removeAttribute()

void donner::svg::components::AttributesComponent::removeAttribute ( const XMLQualifiedNameRef & name )

inline

Remove an attribute from the element.

Parameters

name	Name of the attribute to remove.

setAttribute()

void donner::svg::components::AttributesComponent::setAttribute ( const XMLQualifiedNameRef & name, const RcString & value )

inline

Set the value of a generic XML attribute, which may be either a presentation attribute or custom user-provided attribute.

This API only stores the underlying strings for the attribute name and value, and does not parse them. To parse, use the upper-layer API: SVGElement::setAttribute.

Parameters

name	Name of the attribute to set.
value	New value to set.
