JsonParserIter

Members

Aliases

Token

alias Token = typeof(super).Token

Import the Token enum into this namespace

Enums

TokenClass

enum TokenClass

TokenClass enum "Other" is for tokens that stand for themselves

Functions

nesting

int nesting()

Returns the nesting level difference caused by the current token.

nextNamed

cstring nextNamed(cstring name, bool found)

Iterates over the json string looking for the named element and returning the value of the following element.

nextNamedBool

bool nextNamedBool(cstring name, bool found)

Iterates over the json string looking for the named element and returning the value of the following element if it is a boolean. If the value is not boolean the search continues.

nextNamedNumber

T nextNamedNumber(cstring name, bool found)

Iterates over the json string looking for the named element and returning the value of the following element if it is a number. If the value is not a number the search continues.

nextNamedObject

bool nextNamedObject(cstring name)

Iterates over the json string looking for the named object and halting iteration if it is found.

nextNamedString

cstring nextNamedString(cstring name, bool found)

Iterates over the json string looking for the named element and returning the value of the following element if it is a string. If the value is not a string the search continues.

nextType

Token nextType()

Steps to the next token in the current JSON content.

opApply

int opApply(int delegate(ref Token type, ref cstring value) dg)

'foreach' iteration over type/value pairs in the current content

opApply

int opApply(int delegate(ref Token type, ref cstring name, ref cstring value) dg)

'foreach' iteration over type/name/value triples in the current content.

opCall

typeof(this) opCall(cstring content)

Resets the instance and sets the input content (convenience wrapper for super.reset()).

skip

uint skip()

Skips the current member so that the next member is reached by a next() call or in the next 'foreach' iteration cycle. That is, - if the current token denotes an object or array beginning, to the corresponding object/array end token, - if the current token is a name, steps over the name, - if the current member is a value, does nothing.

token_class

TokenClass token_class()

Static variables

nestings

int[Token.max + 1] nestings;

Token nesting difference values

token_classes

TokenClass[Token.max + 1] token_classes;

Token to TokenClass association

type_description

istring[Token.max + 1] type_description;

Token type descriptions
