Detailed Description

数値、文字列などの値を相互変換するクラス

数値の場合doubleまたはint64_tで保持する

数値型であっても文字列のインスタンスを内部に保持し、 ValAdaptorが破棄されるまでの間char*やstring_viewから参照できる

空の状態=空文字列

Member Function Documentation

◆ as()

template<typename T >

double as ( ) const

inline

数値として返す

Since: ver1.10

as<T>(), Tはdoubleなどの実数型、intなどの整数型

Deprecated:: ver2.0〜 asDouble(), asInt(), asLLong() を追加さらにas<T>にはTになにを指定してもdoubleで返るというバグがある

◆ asBool()

bool asBool ( ) const

bool値を返す

Since: ver1.10

文字列型が入っていた場合、空文字列でなければtrueを返す
数値型が入っていた場合、0でなければtrueを返す

◆ asDouble()

double asDouble ( ) const

実数として返す

Since: ver2.0

◆ asInt()

int asInt ( ) const

int型の整数として返す

Since: ver2.0

◆ asLLong()

long long asLLong ( ) const

long long型の整数として返す

Since: ver2.0

◆ asString()

std::string asString ( ) const

inline

文字列として返す(コピー)

Since: ver1.10

◆ asStringRef()

const std::string & asStringRef ( ) const

文字列として返す

Since: ver1.10

std::stringのconst参照を返す。参照はこのValAdaptorが破棄されるまで有効

as_strにstringが格納されていた場合はそれをそのまま返す。そうでない場合(u8string, wstring, double, int64が格納されている場合) はそれをstringに変換したうえでその参照を返す。

◆ asU8StringRef()

const std::string & asU8StringRef ( ) const

Since: ver2.0

◆ asWString()

std::wstring asWString ( ) const

inline

文字列として返す(コピー) (wstring)

Since: ver2.0

◆ asWStringRef()

const std::wstring & asWStringRef ( ) const

文字列として返す (wstring)

Since: ver2.0

See also: asStringRef()

◆ empty()

bool empty ( ) const

値が空かどうか調べる

Since: ver1.11

◆ emptyVal()
