Class `std.encoding.EncodingSchemeASCII`

EncodingScheme to handle ASCII



class EncodingSchemeASCII

  : EncodingScheme
;

This scheme recognises the following names: "ANSI_X3.4-1968", "ANSI_X3.4-1986", "ASCII", "IBM367", "ISO646-US", "ISO_646.irv:1991", "US-ASCII", "cp367", "csASCII" "iso-ir-6", "us"

Properties

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

Methods

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