simpleEscapeIRI
public static void simpleEscapeIRI(String str, Appendable appendable, boolean escapeUnicode) throws IOException
Escapes a string to a (mostly) conforming IRI value and append it to the appendable.Non-ASCII (valid) values can optionally be numerically encoded by setting escapeUnicode to true. Most characters that are invalid in an IRI - like a white space or control character - are percent-encoded.
This is slightly faster than
ParsedIRI.create(String)
for valid IRI (without percents) and much faster for IRI with invalid (percent-encoded) characters, though it is less accurate.- Parameters:
str
-appendable
-escapeUnicode
- escape non-ASCII values numerically- Throws:
IOException
-
appendN
public static void appendN(char c, int n, StringBuilder sb)
Appends the specified character n times to the supplied StringBuilder.- Parameters:
c
- The character to append.n
- The number of times the character should be appended.sb
- The StringBuilder to append the character(s) to.
-
trimDoubleQuotes
public static String trimDoubleQuotes(String text)
Removes the double quote from the start and end of the supplied string if it starts and ends with this character. This method does not create a new string if text doesn't start and end with double quotes, the text object itself is returned in that case.- Parameters:
text
- The string to remove the double quotes from.- Returns:
- The trimmed string, or a reference to text if it did not start and end with double quotes.
