Class Tokenizer

  • Direct Known Subclasses:
    TokenParser
    @Contract(threading=IMMUTABLE)
public class Tokenizer
extends java.lang.Object
    Tokenizer that can be used as a foundation for more complex parsing routines. Methods of this class are designed to produce near zero intermediate garbage and make no intermediate copies of input data.

    This class is immutable and thread safe.

                                     Tokenizer.Delimiter delimiterPredicate)
        Extracts from the sequence of chars a token terminated with any of the given delimiters or a whitespace characters.
        Parameters:
        buf - buffer with the sequence of chars to be parsed
        cursor - defines the bounds and current position of the buffer
        delimiterPredicate - delimiter predicate. Can be null if the token is not delimited by any character.

                                   Tokenizer.Delimiter delimiterPredicate)
        Extracts from the sequence of chars a token terminated with any of the given delimiters discarding semantically insignificant whitespace characters.
        Parameters:
        buf - buffer with the sequence of chars to be parsed
        cursor - defines the bounds and current position of the buffer
        delimiterPredicate - delimiter predicate. Can be null if the token is not delimited by any character.

                                   Tokenizer.Delimiter delimiterPredicate)
        Extracts from the sequence of chars a value which can be enclosed in quote marks and terminated with any of the given delimiters discarding semantically insignificant whitespace characters.
        Parameters:
        buf - buffer with the sequence of chars to be parsed
        cursor - defines the bounds and current position of the buffer

                           Tokenizer.Cursor cursor)
        Skips semantically insignificant whitespace characters and moves the cursor to the closest non-whitespace character.
        Parameters:
        buf - buffer with the sequence of chars to be parsed
        cursor - defines the bounds and current position of the buffer

      • copyContent

        Parameters:
        buf - buffer with the sequence of chars to be parsed
        cursor - defines the bounds and current position of the buffer
        delimiterPredicate - delimiter predicate. Can be null if the token is delimited by a whitespace only.
