Method Detail- 
convertpublic void convert(ByteChunk mb, boolean query) throws java.io.IOException URLDecode, will modify the source. Assumes source bytes are encoded using a superset of US-ASCII as per RFC 7230. "%2f" will be rejected unless the input is a query string.- Parameters:
- mb- The URL encoded bytes
- query-- trueif this is a query string. For a query string '+' will be decoded to ' '
- Throws:
- java.io.IOException- Invalid %xx URL encoding
 
 - 
convertpublic void convert(ByteChunk mb, EncodedSolidusHandling encodedSolidusHandling) throws java.io.IOException URLDecode, will modify the source. Assumes source bytes are encoded using a superset of US-ASCII as per RFC 7230.- Parameters:
- mb- The URL encoded bytes
- encodedSolidusHandling- How should the %2f sequence handled by the decoder? For query strings this parameter will be ignored and the %2f sequence will be decoded
- Throws:
- java.io.IOException- Invalid %xx URL encoding

convert@Deprecated public void convert(CharChunk mb, boolean query) throws java.io.IOException Deprecated.Unused. Will be removed in Tomcat 10In-buffer processing - the buffer will be modified.WARNING: This method assumes US-ASCII encoding. - Parameters:
- mb- The URL encoded chars
- query-- trueif this is a query string
- Throws:
- java.io.IOException- Invalid %xx URL encoding
 
 - 
convert@Deprecated public void convert(MessageBytes mb, boolean query) throws java.io.IOException Deprecated.Unused. Will be removed in Tomcat 10URLDecode, will modify the source.WARNING: This method assumes US-ASCII encoding. - Parameters:
- mb- The URL encoded String, bytes or chars
- query-- trueif this is a query string
- Throws:
- java.io.IOException- Invalid %xx URL encoding
 
 - 
convert@Deprecated public java.lang.String convert(java.lang.String str, boolean query)Deprecated.Unused. Will be removed in Tomcat 10%xx decoding of a string.WARNING: This method assumes US-ASCII encoding. FIXME: this is inefficient. - Parameters:
- str- The URL encoded string
- query-- trueif this is a query string
- Returns:
- the decoded string
 
 - 
URLDecode@Deprecated public static java.lang.String URLDecode(java.lang.String str) Deprecated.Unused. This will be removed in Tomcat 10 onwardsDecode and return the specified URL-encoded String. When the byte array is converted to a string, UTF-8 is used. This may be different than some other servers. It is assumed the string is not a query string.- Parameters:
- str- The url-encoded string
- Returns:
- the decoded string
- Throws:
- java.lang.IllegalArgumentException- if a '%' character is not followed by a valid 2-digit hexadecimal number
 
 - 
URLDecodepublic static java.lang.String URLDecode(java.lang.String str, java.nio.charset.Charset charset)Decode and return the specified URL-encoded String. It is assumed the string is not a query string.- Parameters:
- str- The url-encoded string
- charset- The character encoding to use; if null, UTF-8 is used.
- Returns:
- the decoded string
- Throws:
- java.lang.IllegalArgumentException- if a '%' character is not followed by a valid 2-digit hexadecimal number
