]StreamReader class
Represents a reader that reads characters from a byte stream. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class StreamReader : public System::IO::TextReader
Methods
| Method | Description |
|---|---|
| void Close() override | Closes the current and underlying streams. |
| virtual void Dispose(bool) | Releases all resources used by the current object and closes the undelying stream. |
| void Dispose() override | Releases all resources used by the current object and closes the undelying stream. |
| virtual bool Equals(ptr) | Compares objects using C# Object.Equals semantics. |
| static std::enable_if<IsSmartPtr<T1>::value&&IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&) | Compares reference type objects in C# style. |
| static std::enable_if<!IsSmartPtr<T1>::value&&!IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&) | Compares value type objects in C# style. |
| static bool Equals(float const&, float const&) | Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN. |
| static bool Equals(double const&, double const&) | Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN. |
| virtual bool FastCast(const Details::FastRttiBase&, void **) const | For internal purposes only. |
| SharedPtr<Stream> get_BaseStream() const | Returns a shared pointer to an object that represents the underlying stream. |
| EncodingPtr get_CurrentEncoding() | Returns the currently used encoding. |
| bool get_EndOfStream() | Returns a value that indicates if the end of of stream has been reached. |
| Detail::SmartPtrCounter * GetCounter() | Gets reference counter data structure associated with the object. |
| virtual int32_t GetHashCode() const | Analog of C# Object.GetHashCode() method. Enables hashing of custom objects. |
| virtual const TypeInfo& GetType() const | Gets actual type of object. Analog of C# System.Object.GetType() call. |
| virtual bool Is(const TypeInfo&) const | Check if object represents an instance of type described by targetType. Analog of C# ‘is’ operator. |
| void Lock() | Implements C# lock() statement locking. Call directly or use LockContext sentry object. |
| virtual ptr MemberwiseClone() const | Analog of C# Object.MemberwiseClone() method. Enables cloning custom types. |
| Object() | Creates object. Initializes all internal data structures. |
| Object(Object const&) | Copy constructor. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses. |
| Object& operator=(Object const&) | Assignment operator. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses. |
| int Peek() override | Reads a single character from the stream without changing the stream’s read cursor. |
| int Read() override | Reads a single character from the stream. |
| int Read(ArrayPtr<char_t>, int, int) override | Reads the specified number of characters from the stream, converts them to UTF-16 encoding and writes the resulting UTF-16 characters to the specified character array starting at the specified position. |
| virtual int ReadBlock(ArrayPtr<char_t>, int, int) | Reads the specified maximum number of characters from the current text reader and writes the data to a buffer, starting at the specified index. |
| String ReadLine() override | Reads characters from the stream until the end of the current line. |
| String ReadToEnd() override | Reads characters from the stream until the end of the stream. |
| static bool ReferenceEquals(ptr const&, ptr const&) | Compares objects by reference. |
| static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, T const&) | Compares objects by reference. |
| static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, std::nullptr_t) | Reference-compares value type object with nullptr. |
| bool ReferenceEquals(String const&, std::nullptr_t) | Specialization of Object::ReferenceEquals for case of string and nullptr. |
| bool ReferenceEquals(String const&, String const&) | Specialization of Object::ReferenceEquals for case of strings. |
| int RemovedSharedRefs(int) | Decreases shared reference count by specified value. |
| virtual void SetTemplateWeakPtr(uint32_t) | Set n’th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode. |
| int SharedCount() const | Gets current value of shared reference counter. |
| Object * SharedRefAdded() | Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector. |
| int SharedRefRemovedSafe() | Decrements and returns shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector. |
