 char[] buff,
 char[] text,
 int start,
 int length,
 boolean forXml)
                      throws IOException

 boolean escapeIsocode,
 char[] buff,
 String text,
 char[] textBuff,
 boolean forXml)
                      throws IOException

writeAttribute

public static void writeAttribute(Writer out,

 String text,
 char[] textBuff,
 boolean isScriptInAttributeValueEnabled,
 boolean forXml)
                           throws IOException

Write a string attribute. Note that this code is duplicated below for character arrays - change both places if you make any changes!!!

Throws:

IOException

writeAttribute

public static void writeAttribute(Writer out,
 boolean escapeUnicode,
 boolean escapeIsocode,
 char[] buff,
 char[] text,
 int start,
 int length,
 boolean isScriptInAttributeValueEnabled,
 boolean forXml)
                           throws IOException

Write a character array attribute. Note that this code is duplicated above for string - change both places if you make any changes!!!

Throws:

IOException

writeURL

public static void writeURL(Writer out,
 String text,
 char[] textBuff,
 String queryEncoding)
                     throws IOException,
UnsupportedEncodingException

Writes a string into URL-encoded format out to a Writer. All characters before the start of the query string will be encoded using UTF-8. Characters after the start of the query string will be encoded using a client-defined encoding. You'll need to use the encoding that the server will expect. (HTML forms will generate query strings using the character encoding that the HTML itself was generated in.) All characters will be encoded as needed for URLs, with the exception of the percent symbol ("%"). Because this is the character itself used for escaping, attempting to escape this character would cause this code to double-escape some strings. It also may be necessary to pre-escape some characters. In particular, a question mark ("?") is considered the start of the query string.

NOTE: This is method is duplicated below. The difference being the acceptance of a char[] for the text to write. Any changes made here, should be made below.

Parameters:

out - a Writer for the output

text - the unencoded (or partially encoded) String

queryEncoding - the character set encoding for after the first question mark

Throws:

IOException

UnsupportedEncodingException
