CharacterArray is a superclass for all kinds of Strings (i.e. |
68 | 41 |
(singleByte-)Strings, TwoByteStrings and whatever comes in the future. |
154 | 42 |
|
8874 | 43 |
This class is abstract, meaning that there are no instances of it. |
2537 | 44 |
All this class does is provide common protocol for concrete subclasses. |

"return a new string consisting of receivers characters |
4047 |
with all \X-character escapes replaced by corresponding-characters. |
|
4048 |
(similar to the way C-language Strings are converted). |
|
4049 |
The following escapes are supported: |
|
9192 | 4050 |
\r return character |
4051 |
\n newline character |
|
4052 |
\b backspace character |
|
4053 |
\f formfeed character |
|
4054 |
\t tab character |
|
4055 |
\e escape character |
|
4056 |
\\ the \ character itself |
|
4057 |
\nnn three digit octal number defining the characters ascii value |
|
4058 |
\other other |
|
608 | 4059 |
|
4060 |
Notice, that \' is NOT a valid escape, since the general syntax of |
|
4061 |
string constants is not affected by this method. |
|
4062 |
||
4063 |
Although easily implementable, this is NOT done automatically |
|
4064 |
by the compiler (due to a lack of a language standard for this). |
|
4065 |
However, the compiler may detect sends ot #withEscapes to string literals |
|
4066 |
and place a modified string constant into the binary/byte-code. |
|
4067 |
Therefore, no runtime penalty will be payed for using these escapes. |
