Detailed Description

For application developers, this class is internal.

For template tag authors it may be necessary to advance the parser and process contained tags if the tag works in a tag – endtag fashion.

Constructor & Destructor Documentation

◆ Parser()

Parser::Parser	(	const QList< Token > &	tokenList,
		QObject *	parent )

Constructor.

Initialises the Parser with the tokenList.

Definition at line 90 of file parser.cpp.

References Parser(), QObject::QObject(), Cutelee::Engine::defaultLibraries(), QObject::parent(), and QObject::qobject_cast().

Referenced by Parser(), getFilter(), hasNextToken(), parse(), parse(), prependToken(), removeNextToken(), and takeNextToken().

◆ ~Parser()

Parser::~Parser ( )

override

Destructor.

Member Function Documentation

◆ getFilter()

std::shared_ptr< Filter > Parser::getFilter ( const QString & name ) const

Returns the filter object called name or an invalid object if no filter with that name is loaded.

Definition at line 157 of file parser.cpp.

References Parser().

Referenced by Cutelee::FilterExpression::FilterExpression().

◆ hasNextToken()

bool Parser::hasNextToken ( ) const

Returns whether the parser has another token to process.

◆ invalidBlockTag()

void Parser::invalidBlockTag	(	const Token &	token,
		const QString &	command,
		const QStringList &	stopAt = {} )

Definition at line 303 of file parser.cpp.

◆ parse() [1/3]

NodeList Parser::parse	(	Node *	parent,
		const QString &	stopAt )

This is an overloaded method.

See also: parse.

Definition at line 168 of file parser.cpp.

References Parser(), and QObject::parent().

◆ parse() [2/3]

NodeList Parser::parse	(	Node *	parent,
		const QStringList &	stopAt = {} )

Advance the parser, using parent as the parent of new Nodes. The parser will stop if it encounters a tag which is contained in the list stopAt.

For example, the {% if %} tag would stopAt both {% endif %} and {% else %} tags.

◆ parse() [3/3]

NodeList Cutelee::Parser::parse	(	TemplateImpl *	parent,
		const QStringList &	stopAt = {} )

This is an overloaded method.

See also: parse.

References QObject::parent().

◆ prependToken()

void Parser::prependToken ( const Token & token )

protected

Puts the token token to the front of the list to be processed by the parser.

Definition at line 322 of file parser.cpp.

References Parser().

◆ removeNextToken()

void Parser::removeNextToken ( )

Deletes the next token available to the parser.

◆ skipPast()

void Parser::skipPast ( const QString & tag )

Advances the parser to the tag tag. This method is similar to parse, but it does not create nodes for tags encountered.

Definition at line 145 of file parser.cpp.

References Cutelee::BlockToken, hasNextToken(), and takeNextToken().

Referenced by CommentNodeFactory::getNode().

◆ takeNextToken()

Token Parser::takeNextToken ( )

Returns the next token to be processed by the parser. This can be examined in template tag implementations to determine why parsing stopped.

For example, if the {% if %} tag, parsing may stop at an {% else %} tag, in which case parsing should be restarted, or it could stop at an {% endif %} tag, in which case parsing is finished for that node.
