Method Detail

isEscaped

public static boolean isEscaped(java.lang.String str,
                                int pos)

Judges whether to be escaped.

Parameters:

str - Character string including character that judges whether to be escaped

pos - Position of character that judges whether to be escaped

Returns:

The character string is true if escaped.

escape

public static java.lang.String escape(java.lang.String str)

Escapes in the character string.

Converts the following character into the escape sequence.

• HT -> "\t"
• LF -> "\n"
• CR -> "\r"
• FF -> "\f"

Processes neither a single quart nor a double quart.

Parameters:

str - Character string of escape processing object

Returns:

Character string after escape is processed

unescape

public static java.lang.String unescape(java.lang.String str)

Unescapes in the character string.

Converts the following escape sequence into the character.

• "\t" -> HT
• "\n" -> LF
• "\r" -> CR
• "\f" -> FF
• "\"" -> "
• "\'" -> '

Note the point that doesn't become it in a complete inversion of espace().

Parameters:

str - Character string where to be unescaped

Returns:

Character string after it unescapes

toBool

public static boolean toBool(java.lang.String target,
                             java.lang.String yes,
                             java.lang.String no,
                             boolean default_value)

Cconverts the given character string into bool value.

Erase the head/tail blank and replace upper case to lower case

Parameters:

target - Strig for judgment

yes - Charactor string that expresses true.

no - Charactor string that expresses false.

default_value - default

Returns:

Comparative result

unique_sv

public static java.util.Vector<java.lang.String> unique_sv(java.lang.String[] sv)

Deletes repetition from the given character string list.

Parameters:

sv - Character string list

Returns:

List of character string of result
