static char	add(char self, int delta) Enabled:
static int	asInteger(char self) Enabled: Unicode character code
static String	escaped(char self) Enabled: Just the part of a character's quoted form that encodes the character.

Method Detail

asInteger

public static int asInteger(char self)

Enabled: Unicode character code

add

public static char add(char self,
                       int delta)

Enabled:

add

public static void add(char self,
                       char other)

Enabled: Kludge to force overload resolution to prevent a char from successfully Java-coercing, on method.invoke(), to an int.

subtract

public static char subtract(char self,
                            int delta)

Enabled:

subtract

public static int subtract(char self,
                           char other)

Enabled:

next

public static char next(char self)

Enabled:

previous

public static char previous(char self)

Enabled:

min

public static char min(char self,
                       char other)

Enabled:

max

public static char max(char self,
                       char other)

Enabled:

__printOn

public static void __printOn(char self,
                             TextWriter out)
                      throws IOException

Enabled: Unlike Java's Writer.print(char), E's chars print by printing their quoted form.

If you want to contribute the character itself to a TextWriter, print it by doing out print(""+c)

IOException

escaped

public static String escaped(char self)

Enabled: Just the part of a character's quoted form that encodes the character.

In other words, everything except the enclosing quote signs. This is used for composing a quoted character. It is mostly redundant with org.erights.e.elib.tables.Twine#quote and org.erights.e.develop.format.StringHelper#quote, but this one outputs a backslash-en for a newline, rather than the newline itself.
