方法详细资料

parseToken

public String parseToken(CharArrayBuffer buf,
                         ParserCursor cursor,
                         BitSet delimiters)

Extracts from the sequence of chars a token terminated with any of the given delimiters discarding semantically insignificant whitespace characters.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

delimiters - set of delimiting characters. Can be null if the token is not delimited by any character.

parseValue

public String parseValue(CharArrayBuffer buf,
                         ParserCursor cursor,
                         BitSet delimiters)

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.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

delimiters - set of delimiting characters. Can be null if the value is not delimited by any character.

skipWhiteSpace

public void skipWhiteSpace(CharArrayBuffer buf,
                           ParserCursor cursor)

Skips semantically insignificant whitespace characters and moves the cursor to the closest non-whitespace character.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

copyContent

public void copyContent(CharArrayBuffer buf,
                        ParserCursor cursor,
                        BitSet delimiters,
                        StringBuilder dst)

Transfers content into the destination buffer until a whitespace character or any of the given delimiters is encountered.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

delimiters - set of delimiting characters. Can be null if the value is delimited by a whitespace only.

dst - destination buffer

copyUnquotedContent

public void copyUnquotedContent(CharArrayBuffer buf,
                                ParserCursor cursor,
                                BitSet delimiters,
                                StringBuilder dst)

Transfers content into the destination buffer until a whitespace character, a quote, or any of the given delimiters is encountered.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

delimiters - set of delimiting characters. Can be null if the value is delimited by a whitespace or a quote only.

dst - destination buffer

copyQuotedContent

public void copyQuotedContent(CharArrayBuffer buf,
                              ParserCursor cursor,
                              StringBuilder dst)

Transfers content enclosed with quote marks into the destination buffer.

参数:

buf - buffer with the sequence of chars to be parsed

cursor - defines the bounds and current position of the buffer

dst - destination buffer
