EncoderExceptionFallbackBuffer Class

Definition

Throws EncoderFallbackException when an input character cannot be converted to an encoded output byte sequence. This class cannot be inherited.

public ref class EncoderExceptionFallbackBuffer sealed : System::Text::EncoderFallbackBuffer
public sealed class EncoderExceptionFallbackBuffer : System.Text.EncoderFallbackBuffer
type EncoderExceptionFallbackBuffer = class
    inherit EncoderFallbackBuffer
Public NotInheritable Class EncoderExceptionFallbackBuffer
Inherits EncoderFallbackBuffer
Inheritance
EncoderExceptionFallbackBuffer

Remarks

A common reason for an encoding or decoding operation to fail is if the underlying encoding class does not provide a mapping between a character and an equivalent byte sequence. If the input character cannot be converted to an output byte sequence, the encoding operation calls the Fallback method, which throws EncoderFallbackException.

The System.Text.EncoderFallbackBuffer class, which represents a data buffer used in an encoding operation, is the base class for the EncoderExceptionFallbackBuffer class. However, instead of a data buffer, the EncoderExceptionFallbackBuffer class represents a standard behavior wherein an exception is thrown if an encoding operation fails. No actual data buffer exists, and the members designed to manipulate such a buffer do no significant work.

Constructors

EncoderExceptionFallbackBuffer()

Initializes a new instance of the EncoderExceptionFallbackBuffer class.

Properties

Remaining

Gets the number of characters in the current EncoderExceptionFallbackBuffer object that remain to be processed.

Methods

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
Fallback(Char, Char, Int32)

Throws an exception because the input character cannot be encoded. Parameters specify the value and index position of the surrogate pair in the input, and the nominal return value is not used.

Fallback(Char, Int32)

Throws an exception because the input character cannot be encoded. Parameters specify the value and index position of the character that cannot be converted.

GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetNextChar()

Retrieves the next character in the exception fallback buffer.

GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
MovePrevious()

Causes the next call to the GetNextChar() method to access the exception data buffer character position that is prior to the current position.

Reset()

Initializes all data and state information pertaining to this fallback buffer.

(Inherited from EncoderFallbackBuffer)
ToString()

Returns a string that represents the current object.

(Inherited from Object)
