Detailed Description

可写原始数据视图 / Mutable raw data view

Note

该类型不拥有数据，仅保存起始地址和字节数。调用方需要保证被引用对象在视图使用期间 保持有效且可写。 / This type does not own the data. It only stores the start address and byte count. The caller must keep the referenced object alive and writable while the view is in use.

Constructor & Destructor Documentation

RawData() [1/6]

LibXR::RawData::RawData ( void * addr, size_t size )

inline

使用指定地址和大小构造 RawData 对象。 Constructs a RawData object with the specified address and size.

Parameters

addr	数据的起始地址。 The starting address of the data.
size	数据的大小（字节）。 The size of the data (in bytes).

Definition at line 55 of file libxr_type.hpp.

: addr_(addr), size_(size) {}

RawData() [2/6]

template<typename DataType >
requires (!std::is_const_v<DataType> && !std::is_same_v<std::remove_cvref_t<DataType>, RawData>)

LibXR::RawData::RawData ( DataType & data )

inline

从可写对象构造视图 / Construct a view from a writable object

Template Parameters

DataType

对象类型 / Object type

Parameters

data	被引用对象 / Referenced object

Definition at line 71 of file libxr_type.hpp.

                          : addr_(&data), size_(sizeof(DataType))
  {
  }

RawData() [3/6]

LibXR::RawData::RawData ( const RawData & data )

default

拷贝构造函数。 Copy constructor.

Parameters

data	另一个 RawData 对象。 Another RawData object.

RawData() [4/6]

LibXR::RawData::RawData ( char * data )

inline

从 char * 指针构造 RawData，数据大小为字符串长度（不含 \0）。 Constructs RawData from a char * pointer, with size set to the string length (excluding \0).

Parameters

data	C 风格字符串指针。 A C-style string pointer.

Definition at line 92 of file libxr_type.hpp.

: addr_(data), size_(data != nullptr ? std::strlen(data) : 0) {}

RawData() [5/6]

template<size_t N>

LibXR::RawData::RawData ( char(&) data[N] )

inline

从可写字符数组构造文本视图 / Construct a text view from a writable char array

Template Parameters

N	数组长度 / Array length

Parameters

data	被引用字符数组 / Referenced char array

Note

若数组最后一个字符恰为 \\0，则仅裁掉这一个尾随终止符；否则保留整个数组长度。 / If the last array element is \\0, only that trailing terminator is trimmed; otherwise the full array extent is kept.

Definition at line 104 of file libxr_type.hpp.

                           : addr_(data), size_(Detail::TrailingNulTrimmedArraySize(data))
  {
  }

RawData() [6/6]

LibXR::RawData::RawData ( std::string & data )

inlineexplicit

从可写字符串构造文本视图 / Construct a text view from a writable string

Parameters

data	被引用字符串 / Referenced string

Definition at line 112 of file libxr_type.hpp.

      : addr_(data.empty() ? nullptr : data.data()), size_(data.size())
  {
  }

Member Function Documentation

operator=()
