Enumeration Type Documentation

◆ JsonType

enum ola::web::JsonType

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

◆ SchemaKeyword

enum ola::web::SchemaKeyword

The list of valid JSon Schema keywords.

Enumerator
SCHEMA_UNKNOWN	Keywords we don't understand

Function Documentation

◆ JsonTypeToString()

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

Get the string corresponding to a JsonType.

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

◆ KeywordToString()

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

Return the string used by the SchemaKeyword.

◆ LookupKeyword()

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

Map a string to a SchemaKeyword.

Returns: the SchemaKeyword corresponding to the string, or SCHEMA_UNDEFINED.

◆ ParseArray()

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

static

Starts from the first character after the '['.

◆ ParseNumber()

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

static

Parse a JsonNumber

◆ ParseObject()

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

static

Starts from the first character after the '{'.

◆ ParseString()

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

static

Extract a string token from the input.

Parameters

input	A pointer to a pointer with the data. This should point to the first character after the quote (") character.
str	A string object to store the extracted string.
parser	the JsonParserInterface to pass tokens to.

Returns: true if the string was extracted correctly, false otherwise.

◆ StringToJsonType()

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.

◆ TrimWhitespace()

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

static

Trim leading whitespace from a string.

Parameters

input A 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.
