decodePrimary
public java.lang.Long decodePrimary(byte[] b, int offset) throws BinaryInterpreterException
Description copied from class:BinaryFieldInterpreter
Decodes only one data of type T from the given bytes array.
WARNING:
bytes
is supposed to contain enough bytes (>=BinaryFieldInterpreter.NB_BYTES
) from the given offset.- Specified by:
decodePrimary
in classBinaryFieldInterpreter<java.lang.Long>
- Parameters:
b
- Array to use to extract enough bytes so that decoding one data of type T.offset
- Position from which bytes must be read.- Returns:
- The decoded value.
- Throws:
BinaryInterpreterException
- If an error occurs while decoding bytes.
-
getArrayClass
protected java.lang.Class<java.lang.Long[]> getArrayClass()
Description copied from class:BinaryFieldInterpreter
Gets the precise array type.
Generally:
T[].class
, where T must be a concrete class.- Specified by:
getArrayClass
in classBinaryFieldInterpreter<java.lang.Long>
- Returns:
- The class of an array of type T.
-
convertPrimary
protected java.lang.Long convertPrimary(java.lang.Object value) throws BinaryInterpreterException
Description copied from class:BinaryFieldInterpreter
Converts/Casts the given object into an object of type T.- Specified by:
convertPrimary
in classBinaryFieldInterpreter<java.lang.Long>
- Parameters:
value
- The value to cast. (MAY BE NULL)- Returns:
- The casted value.
- Throws:
BinaryInterpreterException
- If there is an error while converting the given value.
-
encodePrimary
public byte[] encodePrimary(java.lang.Long value) throws BinaryInterpreterException
Description copied from class:BinaryFieldInterpreter
Encodes a single value of type T in binary.
NOTE: If the given value is null,
BinaryFieldInterpreter.getPadding()
will be returned.- Specified by:
encodePrimary
in classBinaryFieldInterpreter<java.lang.Long>
- Parameters:
value
- The value to encode. (MAY BE NULL).- Returns:
- The value encoded in binary.
- Throws:
BinaryInterpreterException
- If there is an error while encoding the given value.
