package ParserInput
Returns the character at the given (zero-based) index.
Returns the character at the given (zero-based) index. Note: this method is hot and should be small and efficient. A range-check is not required for the parser to work correctly.
Gets the input line with the given number as a String.
Gets the input line with the given number as a String. Note: the first line is line number one!
The number of characters in this input.
The number of characters in this input. Note: this method is hot and should be small and efficient.
Returns the characters between index start (inclusively) and end (exclusively) as an Array[Char].
Returns the characters between index start (inclusively) and end (exclusively) as an Array[Char].
Returns the characters between index start (inclusively) and end (exclusively) as a String.
Returns the characters between index start (inclusively) and end (exclusively) as a String.
ParserInput reading directly off a byte array. This avoids a separate decoding step but assumes that each byte represents exactly one character, which is encoded by ISO-8859-1! You can therefore use this ParserInput type only if you know that all input will be
ISO-8859-1-encoded, or only contains 7-bit ASCII characters (which is a subset of ISO-8859-1)!Note that this ParserInput type will NOT work with general
UTF-8-encoded input as this can contain character representations spanning multiple bytes. However, if you know that your input will only ever contain 7-bit ASCII characters (0x00-0x7F) then UTF-8 is fine, since the first 127 UTF-8 characters are encoded with only one byte that is identical to 7-bit ASCII and ISO-8859-1.
