Method Detail

parseField

public int parseField(byte[] bytes,
             int startPos,
             int limit,
             byte[] delim,
             BooleanValue reuse)

Description copied from class: FieldParser

Parses the value of a field from the byte array. The start position within the byte array and the array's valid length is given. The content of the value is delimited by a field delimiter.

Specified by:

parseField in class FieldParser<BooleanValue>

Parameters:

bytes - The byte array that holds the value.

startPos - The index where the field starts

limit - The limit unto which the byte contents is valid for the parser. The limit is the position one after the last valid byte.

delim - The field delimiter character

reuse - An optional reusable field to hold the value

Returns:

The index of the next delimiter, if the field was parsed correctly. A value less than 0 otherwise.

getLastResult

public BooleanValue 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<BooleanValue>

Returns:

The latest parsed field.

createValue

public BooleanValue createValue()

Description copied from class: FieldParser

Returns an instance of the parsed value type.

Specified by:

createValue in class FieldParser<BooleanValue>

Returns:

An instance of the parsed value type.
