a parser reading from an input adapter

Member Function Documentation

◆ accept()

bool nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer >::parser::accept ( const bool strict = true )

public accept interface

Parameters

[in] strict whether to expect the last token to be EOF

Returns: whether the input is a proper JSON text

◆ accept_internal()

bool nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer >::parser::accept_internal ( )

inlineprivate

the acutal acceptor

Invariant

1. The last token is not yet processed. Therefore, the caller of this function must make sure a token has been read.

When this function returns, the last token is processed. That is, the last read character was already considered.

This invariant makes sure that no token needs to be "unput".

◆ expect()

Args > class ArrayType = std::vector, class StringType = std::string, class BooleanType = bool, class NumberIntegerType = std::int64_t, class NumberUnsignedType = std::uint64_t, class NumberFloatType = double, template< typename U > class AllocatorType = std::allocator, template< typename T, typename SFINAE=void > class JSONSerializer = adl_serializer>

Exceptions

parse_error.101 if expected token did not occur
