class System.Text.EncoderReplacementFallbackBuffer
Assembly: System.Runtime
Inheritance: object → EncoderFallbackBuffer → EncoderReplacementFallbackBuffer
Represents a substitute input string that is used when the original input character cannot be encoded. This class cannot be inherited.
Properties
public
int
Remaining
Gets the number of characters in the replacement fallback buffer that remain to be processed.
Methods
public
bool
Fallback(char charUnknownHigh,
char charUnknownLow,
int index)
Indicates whether a replacement string can be used when an input surrogate pair cannot be encoded, or whether the surrogate pair can be ignored. Parameters specify the surrogate pair and the index position of the pair in the input.
Returns <see langword="true" /> if the replacement string is not empty; <see langword="false" /> if the replacement string is empty.
charUnknownHigh
The high surrogate of the input pair.
charUnknownLow
The low surrogate of the input pair.
index
The index position of the surrogate pair in the input buffer.
public
bool
Fallback(char charUnknown,
int index)
Prepares the replacement fallback buffer to use the current replacement string.
Returns <see langword="true" /> if the replacement string is not empty; <see langword="false" /> if the replacement string is empty.
charUnknown
An input character. This parameter is ignored in this operation unless an exception is thrown.
index
The index position of the character in the input buffer. This parameter is ignored in this operation.
public
char
GetNextChar()
Retrieves the next character in the replacement fallback buffer.
Returns The next Unicode character in the replacement fallback buffer that the application can encode.
public
bool
MovePrevious()
Causes the next call to the <see cref="M:System.Text.EncoderReplacementFallbackBuffer.GetNextChar" /> method to access the character position in the replacement fallback buffer prior to the current character position.
Returns <see langword="true" /> if the <see cref="M:System.Text.EncoderReplacementFallbackBuffer.MovePrevious" /> operation was successful; otherwise, <see langword="false" /> .
public
void
Reset()
Initializes all internal state information and data in this instance of <see cref="T:System.Text.EncoderReplacementFallbackBuffer" /> .
public
bool
Equals(object obj)
Inherited from object
Determines whether the specified object is equal to the current object.
Returns <see langword="true" /> if the specified object is equal to the current object; otherwise, <see langword="false" /> .
obj
The object to compare with the current object.
protected
void
Finalize()
Inherited from object
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
public
int
GetHashCode()
Inherited from object
Serves as the default hash function.
Returns A hash code for the current object.
public
Type
GetType()
Inherited from object
Gets the <see cref="T:System.Type" /> of the current instance.
Returns The exact runtime type of the current instance.
protected
object
MemberwiseClone()
Inherited from object
Creates a shallow copy of the current <see cref="T:System.Object" /> .
Returns A shallow copy of the current <see cref="T:System.Object" /> .
public
string
ToString()
Inherited from object
Returns a string that represents the current object.
Returns A string that represents the current object.
