CookieTokenizer

• java.lang.Object

Fields Summary
private static final int	MAX_COOKIE_TOKENS Upper bound on the number of cookie tokens to accept. The limit is based on the 4 different attributes (4.3.4) and the 20 cookie minimum (6.3) given in RFC 2109 multiplied by 2 to accomodate the 2 tokens in each name=value pair ("JSESSIONID=1234" is 2 tokens).
private String[]	tokens Array of cookie tokens. Even indices contain name tokens while odd indices contain value tokens (or null).
private int	numTokens Number of cookie tokens currently in the tokens[] array.

Methods Summary
public int	getNumTokens() Return the number of cookie tokens parsed from the Cookie: header. return numTokens;
private int	parseNameValue(java.lang.String cookies, int beginIndex) Parse a name=value pair from the Cookie: header. param cookies The Cookie: header to parse param beginIndex The index in cookies to begin parsing from, inclusive int length = cookies.length(); int index = beginIndex; while (index < length) { switch (cookies.charAt(index)) { case ';": case ',": // Found end of name token without value tokens[numTokens] = cookies.substring(beginIndex, index).trim(); if (tokens[numTokens].length() > 0) { numTokens++; tokens[numTokens] = null; numTokens++; } return index + 1; case '=": // Found end of name token with value tokens[numTokens] = cookies.substring(beginIndex, index).trim(); numTokens++; return parseValue(cookies, index + 1); case '"": // Skip past quoted span do index++; while (cookies.charAt(index) != '""); break; } index++; } if (index > beginIndex) { // Found end of name token without value tokens[numTokens] = cookies.substring(beginIndex, index).trim(); if (tokens[numTokens].length() > 0) { numTokens++; tokens[numTokens] = null; numTokens++; } } return index;
private int	parseValue(java.lang.String cookies, int beginIndex) Parse the value token from a name=value pair. param cookies The Cookie: header to parse param beginIndex The index in cookies to begin parsing from, inclusive int length = cookies.length(); int index = beginIndex; while (index < length) { switch (cookies.charAt(index)) { case ';": case ',": // Found end of value token tokens[numTokens] = cookies.substring(beginIndex, index).trim(); numTokens++; return index + 1; case '"": // Skip past quoted span do index++; while (cookies.charAt(index) != '""); break; } index++; } // Found end of value token tokens[numTokens] = cookies.substring(beginIndex, index).trim(); numTokens++; return index;
public java.lang.String	tokenAt(int index) Returns a given cookie token from the Cookie: header. param index The index of the cookie token to return return tokens[index];
public int	tokenize(java.lang.String cookies) Parse the name=value tokens from a Cookie: header. param cookies The Cookie: header to parse numTokens = 0; if (cookies != null) { try { // Advance through cookies, parsing name=value pairs int length = cookies.length(); int index = 0; while (index < length) index = parseNameValue(cookies, index); } catch (ArrayIndexOutOfBoundsException e) { // Filled up the tokens[] array } catch (IndexOutOfBoundsException e) { // Walked off the end of the cookies header } } return numTokens;
