Member Function Documentation

visitNull()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitNull ( const SourceLocation &  source, Null  value  )

inlinevirtual

Callback for values of type Null.

Parameters

source	location of the parsed value.
value	parsed value.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.

visitBoolean()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitBoolean ( const SourceLocation &  source, Boolean  value  )

inlinevirtual

Callback for values of type Boolean.

Parameters

source	location of the parsed value.
value	parsed value.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.

visitString()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitString ( const SourceLocation &  source, String &&  value  )

inlinevirtual

Callback for values of type String.

Parameters

source	location of the parsed value.
value	parsed value.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.

visitNumber()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitNumber ( const SourceLocation &  source, Number  value  )

inlinevirtual

Callback for values of type Number.

Parameters

source	location of the parsed value.
value	parsed value.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.

visitObject()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitObject ( const SourceLocation &  source, Parser &  parser  )

inlinevirtual

Callback for objects.

Parameters

source	location of the beginning of the encountered object.
parser	parser that should be used to parse the object.

Warning

Implementations must advance the parser to the end of the encountered object, past the last closing curly brace.

Implementations must not advance the parser past the end of the encountered object.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.

visitArray()

template<typename It >

virtual void donut::json::Parser< It >::ValueVisitor::visitArray ( const SourceLocation &  source, Parser &  parser  )

inlinevirtual

Callback for arrays.

Parameters

source	location of the beginning of the encountered array.
parser	parser that should be used to parse the array.

Warning

Implementations must advance the parser to the end of the encountered array, past the last closing square bracket.

Implementations must not advance the parser past the end of the encountered array.

Exceptions

json::Error	on invalid input.
any	exception thrown by the concrete implementation.

Reimplemented in donut::json::Parser< It >::ConcreteValueVisitor< Visitor >, and donut::json::Parser< It >::SkipValueVisitor.
