java.lang.Objectorg.apache.james.mime4j.stream.RawFieldParser
public class RawFieldParser
Low level parser for header field elements. The parsing routines 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.

void |
copyContent(ByteSequence buf,

ParserCursor cursor,
java.lang.StringBuilder dst)
Transfers content enclosed with quote marks into the destination buffer. |

RawField |
parseField(ByteSequence raw)
Parses the sequence of bytes into RawField . |
NameValuePair |
parseParameter(ByteSequence buf,
ParserCursor cursor)
Parses the sequence of bytes containing a field parameter delimited with semicolon into NameValuePair . |
java.util.List<NameValuePair> |
parseParameters(ByteSequence buf,
ParserCursor cursor)
Parses the sequence of bytes containing field parameters delimited with semicolon into a list of NameValuePair s. |
RawBody |
parseRawBody(ByteSequence buf,
ParserCursor cursor)
Parses the sequence of bytes containing a value with parameters into RawBody . |
RawBody |
parseRawBody(RawField field)
Parses the field body containing a value with parameters into RawBody . |
java.lang.String |
parseToken(ByteSequence buf,
ParserCursor cursor,
java.util.BitSet delimiters)
Extracts from the sequence of bytes a token terminated with any of the given delimiters discarding semantically insignificant whitespace characters and comments. |
java.lang.String |
parseValue(ByteSequence buf,
ParserCursor cursor,
java.util.BitSet delimiters)
Extracts from the sequence of bytes a value which can be enclosed in quote marks and terminated with any of the given delimiters discarding semantically insignificant whitespace characters and comments. |
void |
skipAllWhiteSpace(ByteSequence buf,
ParserCursor cursor)
Skips semantically insignificant whitespace characters and comments and moves the cursor to the closest semantically significant non-whitespace character. |
void |
skipComment(ByteSequence buf,
ParserCursor cursor)
Skips semantically insignificant content if the current position is positioned at the beginning of a comment and moves the cursor past the end of the comment. |
void |
skipWhiteSpace(ByteSequence buf,
ParserCursor cursor)
Skips semantically insignificant whitespace characters and moves the cursor to the closest non-whitespace character. |
