Method Detail

parseField

public int parseField(byte[] bytes,
                      int startPos,
                      int limit,
                      byte[] delimiter,
                      Timestamp reusable)

Description copied from class: FieldParser

Each parser's logic should be implemented inside this method

Specified by:

parseField in class FieldParser<Timestamp>

createValue

public Timestamp createValue()

Description copied from class: FieldParser

Returns an instance of the parsed value type.

Specified by:

createValue in class FieldParser<Timestamp>

Returns:

An instance of the parsed value type.

getLastResult

public Timestamp getLastResult()

Description copied from class: FieldParser

Gets the parsed field. This method returns the value parsed by the last successful invocation of FieldParser.parseField(byte[], int, int, byte[], Object). It objects are mutable and reused, it will return the object instance that was passed the parse function.

Specified by:

getLastResult in class FieldParser<Timestamp>

Returns:

The latest parsed field.

parseField

public static final Timestamp parseField(byte[] bytes,
                                         int startPos,
                                         int length)

Static utility to parse a field of type Timestamp from a byte sequence that represents text characters (such as when read from a file stream).

Parameters:

bytes - The bytes containing the text data that should be parsed.

startPos - The offset to start the parsing.

length - The length of the byte sequence (counting from the offset).

Returns:

The parsed value.

Throws:

IllegalArgumentException - Thrown when the value cannot be parsed because the text represents not a correct number.

parseField

public static final Timestamp parseField(byte[] bytes,
                                         int startPos,
                                         int length,
                                         char delimiter)

Static utility to parse a field of type Timestamp from a byte sequence that represents text characters (such as when read from a file stream).

Parameters:

bytes - The bytes containing the text data that should be parsed.

startPos - The offset to start the parsing.

length - The length of the byte sequence (counting from the offset).

delimiter - The delimiter that terminates the field.

Returns:

The parsed value.

Throws:

IllegalArgumentException - Thrown when the value cannot be parsed because the text represents not a correct number.
