## org.modeshape.graph.query.parse
Class SqlQueryParser.SqlTokenizer

    java.lang.Object
      org.modeshape.graph.query.parse.SqlQueryParser.SqlTokenizer

All Implemented Interfaces:
  TokenStream.Tokenizer

Enclosing class:
  SqlQueryParser

    public static class SqlQueryParser.SqlTokenizer

extends Object
implements TokenStream.Tokenizer

A `TokenStream.Tokenizer` implementation that parses words, quoted phrases, comments, and symbols. Words are delimited by whitespace and consist only of alpha-number characters plus the underscore character. Quoted phrases are delimited by single-quote and double-quote characters (which may be escaped within the quote). Comments are the characters starting with '/*' and ending with '*/', or starting with '--' and ending with the next line terminator (or the end of the content).

Field Summary
`static int` | `COMMENT` The token type for tokens that consist of all the characters between "/*" and "*/" or between "--" and the next line terminator (e.g., '\n', '\r' or "\r\n")
`static int` | `OTHER` The token type for tokens that consist of other characters.
`static int` | `QUOTED_STRING` The token type for tokens that consist of all the characters within single-quotes, double-quotes, or square brackets.
`static int` | `SYMBOL` The token type for tokens that consist of an individual "symbol" character.
`static int` | `WORD` The token type for tokens that represent an unquoted string containing a character sequence made up of non-whitespace and non-symbol characters.

Constructor Summary
`SqlQueryParser.SqlTokenizer(boolean useComments)`

Method Summary
`void` | `tokenize(TokenStream.CharacterStream input, TokenStream.Tokens tokens)` Process the supplied characters and construct the appropriate `TokenStream.Token` objects.

Constructor Detail

### SqlQueryParser.SqlTokenizer

    public SqlQueryParser.SqlTokenizer(boolean useComments)

Method Detail

### tokenize

    public void tokenize(TokenStream.CharacterStream input,
                         TokenStream.Tokens tokens)
                  throws ParsingException

  Process the supplied characters and construct the appropriate `TokenStream.Token` objects.

  Specified by:
    `tokenize` in interface `TokenStream.Tokenizer`
  Parameters:
    `input` - the character input stream; never null
    `tokens` - the factory for `TokenStream.Token` objects, which records the order in which the tokens are created
  Throws:
    `ParsingException` - if there is an error while processing the character stream (e.g., a quote is not closed, etc.)
