JsonParserIter

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()
