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. |

The following escapes are supported: |

9192 | 4284 |
\r return character |
4285 |
\n newline character |
|
4286 |
\b backspace character |

Notice, that \' is NOT a valid escape, since the general syntax of |

string constants is not affected by this method. |
|
4296 |
||
4297 |
Although easily implementable, this is NOT done automatically |
|
4298 |
by the compiler (due to a lack of a language standard for this). |
|
4299 |
However, the compiler may detect sends ot #withEscapes to string literals |
|
4300 |
and place a modified string constant into the binary/byte-code. |
|
4301 |
Therefore, no runtime penalty will be payed for using these escapes. |
