Detailed Description

A type representing a JSON number.

The design of the struct is deliberately straight-forward. All functions return standard values with no error check.

◆ append_double()

simdjson_inline void simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::append_double ( double value )

protectednoexcept

Store a double value to the number.

Definition at line 95 of file json_type-inl.h.

◆ append_s64()

simdjson_inline void simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::append_s64 ( int64_t value )

protectednoexcept

Store a signed 64-bit value to the number.

Definition at line 85 of file json_type-inl.h.

◆ append_u64()

simdjson_inline void simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::append_u64 ( uint64_t value )

protectednoexcept

Store an unsigned 64-bit value to the number.

Definition at line 90 of file json_type-inl.h.

◆ as_double()

simdjson_inline double simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::as_double ( ) const

noexcept

Convert the number to a double.

Though it always succeed, the conversion may be lossy if the number cannot be represented exactly.

Definition at line 75 of file json_type-inl.h.

Definition at line 67 of file json_type-inl.h.

◆ get_int64()

simdjson_inline int64_t simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::get_int64 ( ) const

Definition at line 55 of file json_type-inl.h.

◆ get_number_type()

simdjson_inline number_type simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::get_number_type ( ) const

noexcept

return the automatically determined type of the number: number_type::floating_point_number, number_type::signed_integer or number_type::unsigned_integer.

enum class number_type { floating_point_number=1, /// a binary64 number signed_integer, /// a signed integer that fits in a 64-bit word using two's complement unsigned_integer /// a positive integer larger or equal to 1<<63 };

Definition at line 35 of file json_type-inl.h.

◆ get_uint64()

simdjson_inline uint64_t simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::get_uint64 ( ) const

◆ is_int64()

simdjson_inline bool simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::is_int64 ( ) const

noexcept

return true if the automatically determined type of the number is number_type::signed_integer.

Definition at line 51 of file json_type-inl.h.

◆ is_uint64()

simdjson_inline bool simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::is_uint64 ( ) const

noexcept

return true if the automatically determined type of the number is number_type::unsigned_integer.

Definition at line 39 of file json_type-inl.h.

noexcept

Definition at line 59 of file json_type-inl.h.

◆ operator uint64_t()

simdjson_inline simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::operator uint64_t ( ) const

noexcept

Definition at line 47 of file json_type-inl.h.

◆ skip_double()

simdjson_inline void simdjson::SIMDJSON_IMPLEMENTATION::ondemand::number::skip_double ( )

protectednoexcept
