Enumeration Type Documentation

The type of JSON data element.

This comes from section 3.5 of the JSON Schema core document.

Enumerator
JSON_ARRAY 

An Array

JSON_BOOLEAN 

A boolean

JSON_INTEGER 

An integer

JSON_NULL 

A null value

JSON_NUMBER 

A number

JSON_OBJECT 

An object

JSON_STRING 

A string

JSON_UNDEFINED 

A unknown type

The list of valid JSon Schema keywords.

Enumerator
SCHEMA_UNKNOWN 

Keywords we don't understand

Function Documentation

std::string ola::web::JsonTypeToString ( JsonType  type)

Get the string corresponding to a JsonType.

e.g. TypeToString(JSON_STRING) returns "string".

std::string ola::web::KeywordToString ( SchemaKeyword  keyword)

Return the string used by the SchemaKeyword.

SchemaKeyword ola::web::LookupKeyword ( const std::string &  keyword)

Map a string to a SchemaKeyword.

Returns
the SchemaKeyword corresponding to the string, or SCHEMA_UNDEFINED.
static bool ola::web::ParseArray ( const char **  input,
JsonParserInterface *  parser 
)
static

Starts from the first character after the '['.

static bool ola::web::ParseNumber ( const char **  input,
JsonParserInterface *  parser 
)
static

Parse a JsonNumber

static bool ola::web::ParseObject ( const char **  input,
JsonParserInterface *  parser 
)
static

Starts from the first character after the '{'.

static bool ola::web::ParseString ( const char **  input,
string *  str,
JsonParserInterface *  parser 
)
static

Extract a string token from the input.

Parameters
inputA pointer to a pointer with the data. This should point to the first character after the quote (") character.
strA string object to store the extracted string.
parserthe JsonParserInterface to pass tokens to.
Returns
true if the string was extracted correctly, false otherwise.
JsonType ola::web::StringToJsonType ( const std::string &  type)

Convert a string to a JsonType.

Returns
The JsonType, or JSON_UNDEFINED if the string isn't a valid type.

e.g. StringToType("string") returns JSON_STRING.

static bool ola::web::TrimWhitespace ( const char **  input)
static

Trim leading whitespace from a string.

Parameters
inputA pointer to a pointer with the data. This is updated to point to the first non-whitespace character.
Returns
true if more data remains, false if the string is now empty.
Note
This is static within JsonLexer.cpp because we should be using strings rather than char[]s. The only reason this doesn't use a string is because I think we'll need a wchar on Windows.
