Field Detail

### currentToken

    protected static String currentToken

  The current token. Currently forAllParameterTypes and forAllClassTagTokens set it and currentToken returns the value. Tokens are computed for cases where the value should be tokenized by a set of delimiters.

### tagTokenizer

    protected static StringTokenizer tagTokenizer

  The StringTokenizer object doing the tokenization. It should be shared by different tag implementations, that's why its defined class-level.

### matchPattern

    protected static String matchPattern

  Template can use matchPattern as a place where they can put volatile variable. You can set the value somewhere in the template and later use the value.
