Detailed Description

Base class for all json types.

This is the base class for all json types

• array
• object
• string
• number
• boolean
• null

It provides all accessors to get the values for each concrete class.

Constructor & Destructor Documentation

oos::json_type::json_type ( const std::string &  name )

explicitprotected

Creates a json_type of a certain type

Parameters

name	Type of the json_type

Member Function Documentation

virtual json_value& oos::json_type::operator[] ( const std::string &  key )

virtual

Returns a json_value with the given key. If the concrete type doesn't support this method an exception is thrown.

Parameters

key	The key of the json_value.

Returns

the corresponding json_value.

Reimplemented in oos::json_object.

virtual json_value& oos::json_type::operator[] ( size_t  index )

virtual

Returns a json_value at the given index. If the concrete type doesn't support this method an exception is thrown.

Parameters

index

The index of the json_value.

Returns

the corresponding json_value.

Reimplemented in oos::json_array.

virtual const json_value& oos::json_type::operator[] ( size_t  index ) const

virtual

Returns a json_value at the given index. If the concrete type doesn't support this method an exception is thrown.

Parameters

index

The index of the json_value.

Returns

the corresponding json_value.

Reimplemented in oos::json_array.

virtual bool oos::json_type::parse ( std::istream &  in )

pure virtual

Parses in json input stream

Parameters

in	The json input stream

Returns

True if stream was parsed correctly

Implemented in oos::json_string, oos::json_number, oos::json_array, oos::json_object, oos::json_bool, and oos::json_null.

virtual void oos::json_type::print ( std::ostream &  out ) const

pure virtual

Prints the json type (tree) to a output stream.

Parameters

out	The stream to write on.

Implemented in oos::json_string, oos::json_number, oos::json_array, oos::json_object, oos::json_bool, and oos::json_null.

virtual void oos::json_type::push_back ( const json_value &  x )

virtual

Adds a json_value to the current value. If the concrete type doesn't support this method an exception is thrown.

Parameters

x	The json_value to add.

Reimplemented in oos::json_array.

virtual size_t oos::json_type::size ( ) const

virtual

Returns the size of the json_value. If the concrete type doesn't support this method an exception is thrown.

Returns

The size of the json_value.

Reimplemented in oos::json_object, and oos::json_array.

std::string oos::json_type::type

(

)

const

Return the type string of the json_type.

Returns

The type string.

void oos::json_type::type ( const std::string &  type )

protected

Sets the type string of the json_type.

Parameters

type	The type string to set

Friends And Related Function Documentation

OOS_API std::ostream& operator<< ( std::ostream &  str, const json_type &  value  )

friend

Output operator for json_type. Each concrete type overloads a print method, to have it print out correctly.

Parameters

str	The output stream to print on.
value	The json_type to print.

Returns

The modified output stream.

OOS_API std::istream& operator>> ( std::istream &  str, json_object &  obj  )

friend

Input operator for json_object. In order to parse an object the corresponding input operator needs access to json_type.

Parameters

str	The input stream to print on.
obj	The json_object to parse.

Returns

The modified input stream.

OOS_API std::istream& operator>> ( std::istream &  str, json_array &  obj  )

friend

Input operator for json_array. In order to parse an array the corresponding input operator needs access to json_type.

Parameters

str	The input stream to print on.
obj	The json_array to parse.

Returns

The modified input stream.
