Class std.encoding.EncodingScheme

Abstract base class of all encoding schemes

class EncodingScheme ;


replacementSequence[get] immutable(ubyte)[]Returns the sequence of ubytes to be used to represent any character which cannot be represented in the encoding scheme.


canEncode (c) Returns true if the character c can be represented in this encoding scheme.
count (s) Returns the total number of code points encoded in a ubyte array.
create (encodingName) Obtains a subclass of EncodingScheme which is capable of encoding and decoding the named encoding scheme.
decode (s) Decodes a single code point.
encode (c, buffer) Encodes a single code point into a user-supplied, fixed-size buffer.
encodedLength (c) Returns the number of ubytes required to encode this code point.
firstSequence (s) Returns the length of the first encoded sequence.
index (s, n) Returns the array index at which the (n+1)th code point begins.
isValid (s) Returns true if the array is encoded correctly
names () Returns an array of all known names for this encoding scheme
register () Registers a subclass of EncodingScheme.
safeDecode (s) Decodes a single code point. The input does not have to be valid.
sanitize (s) Sanitizes an array by replacing malformed ubyte sequences with valid ubyte sequences. The result is guaranteed to be valid for this encoding scheme.
toString () Returns the standard name of the encoding scheme
validLength (s) Returns the length of the longest possible substring, starting from the first element, which is validly encoded.
factory (classname) Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
opCmp (o) Compare with another Object obj.
opEquals (o) Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides and overloads for opEquals should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for null on the typed overload.
toHash () Compute hash function for Object.
toString () Convert Object to a human readable string.
