Classes

Public Member Functions
	FakeElement (const xml::XMLQualifiedNameRef &tagName="unknown")
	Construct a fake element with the given tag name.
DeferredPrinter	printAsTree () const
	When used in an ostream output stream, prints the element's and all children instead of just the element.
bool	operator< (const FakeElement &other) const
	Comparison operator, uses pointer comparison for simplicity.
Core API that satisfies the \ref ElementLike concept
bool	operator== (const FakeElement &other) const
	Equality operator.
xml::XMLQualifiedNameRef	tagName () const
	Get the XML tag name string for this element.
bool	isKnownType () const
	Returns true if this is a known element type. For FakeElement, returns false for "unknown" elements.
RcString	id () const
	Gets the element id, the value of the "id" attribute.
RcString	className () const
	Gets the element class name, the value of the "class" attribute.
std::optional< RcString >	getAttribute (const xml::XMLQualifiedNameRef &name) const
	Get the value of an attribute, if it exists.
SmallVector< xml::XMLQualifiedNameRef, 1 >	findMatchingAttributes (const xml::XMLQualifiedNameRef &matcher) const
	Find attributes matching the given name matcher.
std::optional< FakeElement >	parentElement () const
	Get this element's parent, if it exists.
std::optional< FakeElement >	firstChild () const
	Get the first child of this element, if it exists.
std::optional< FakeElement >	lastChild () const
	Get the last child of this element, if it exists.
std::optional< FakeElement >	previousSibling () const
	Get the previous sibling of this element, if it exists.
std::optional< FakeElement >	nextSibling () const
	Get the next sibling of this element, if it exists.
Mutator methods
void	setId (const RcString &id)
	Sets the element id, the value of the "id" attribute.
void	setClassName (const RcString &className)
	Sets the element class name, the value of the "class" attribute.
void	setAttribute (const xml::XMLQualifiedNameRef &name, const RcString &value)
	Sets the value of an attribute.
void	appendChild (const FakeElement &child)
	Appends a new child to this element's child list.

Friends
std::ostream &	operator<< (std::ostream &os, const FakeElement &elem)
	Ostream output operator, which outputs the element's tag name, id, class name, and attributes like a CSS selector.

Detailed Description

A test fake for a type that satisfies the ElementLike concept.

This is used for testing purposes, and has simple implementations for each API.

Examples

custom_css_parser.cc.

Constructor & Destructor Documentation

FakeElement()

donner::FakeElement::FakeElement ( const xml::XMLQualifiedNameRef & tagName = "unknown" )

inlineexplicit

Construct a fake element with the given tag name.

Parameters

tagName

The XML tag name for this element.

Member Function Documentation

findMatchingAttributes()

SmallVector< xml::XMLQualifiedNameRef, 1 > donner::FakeElement::findMatchingAttributes ( const xml::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.

firstChild()

std::optional< FakeElement > donner::FakeElement::firstChild ( ) const

inline

Get the first child of this element, if it exists.

Returns

The first child element, or std::nullopt if the element has no children.

getAttribute()

std::optional< RcString > donner::FakeElement::getAttribute ( const xml::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.

lastChild()

std::optional< FakeElement > donner::FakeElement::lastChild ( ) const

inline

Get the last child of this element, if it exists.

Returns

The last child element, or std::nullopt if the element has no children.

nextSibling()

std::optional< FakeElement > donner::FakeElement::nextSibling ( ) const

inline

Get the next sibling of this element, if it exists.

Returns

The next sibling element, or std::nullopt if the element has no next sibling.

parentElement()

std::optional< FakeElement > donner::FakeElement::parentElement ( ) const

inline

Get this element's parent, if it exists.

If the parent is not set, this document is either the root element or has not been inserted into the document tree.

Returns

The parent element, or std::nullopt if the parent is not set.

previousSibling()

std::optional< FakeElement > donner::FakeElement::previousSibling ( ) const

inline

Get the previous sibling of this element, if it exists.

Returns

The previous sibling element, or std::nullopt if the element has no previous sibling.

printAsTree()

DeferredPrinter donner::FakeElement::printAsTree ( ) const

inline

When used in an ostream output stream, prints the element's and all children instead of just the element.

Example usage:

FakeElement element;
std::cout << element.printAsTree() << "\n";

Examples

custom_css_parser.cc.
