Method Summary

Modifier and Type	Method	Description
default BigDecimal	getBigDecimal(int index, int numBytesPerValue)
byte[]	getBytes(int index, int numBytesPerValue)	NOTE: Do not reuse buffer for BYTES because the return value can have variable length.
double	getDouble(int index)
float	getFloat(int index)
int	getInt(int index)
long	getLong(int index)
String	getPaddedString(int index, int numBytesPerValue, byte[] buffer)	NOTE: The passed in reusable buffer should have capacity of at least numBytesPerValue.
byte[]	getUnpaddedBytes(int index, int numBytesPerValue, byte paddingByte, byte[] buffer)	Get un-padded bytes for string.
String	getUnpaddedString(int index, int numBytesPerValue, byte paddingByte, byte[] buffer)	NOTE: The passed in reusable buffer should have capacity of at least numBytesPerValue.
