Method Detail

decodePrimary
public java.lang.Double decodePrimary(byte[] bytes, int offset) throws BinaryInterpreterExceptionDescription copied from class:BinaryFieldInterpreterDecodes only one data of type T from the given bytes array.
WARNING:
bytesis supposed to contain enough bytes (>=BinaryFieldInterpreter.NB_BYTES) from the given offset.- Specified by:
decodePrimaryin classBinaryFieldInterpreter<java.lang.Double>- Parameters:
bytes- 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.Double[]> getArrayClass()
Description copied from class:BinaryFieldInterpreterGets the precise array type.
Generally:
T[].class, where T must be a concrete class.- Specified by:
getArrayClassin classBinaryFieldInterpreter<java.lang.Double>- Returns:
- The class of an array of type T.
-
convertPrimary
protected java.lang.Double convertPrimary(java.lang.Object value) throws BinaryInterpreterExceptionDescription copied from class:BinaryFieldInterpreterConverts/Casts the given object into an object of type T.- Specified by:
convertPrimaryin classBinaryFieldInterpreter<java.lang.Double>- 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.Double value) throws BinaryInterpreterExceptionDescription copied from class:BinaryFieldInterpreterEncodes a single value of type T in binary.
NOTE: If the given value is null,
BinaryFieldInterpreter.getPadding()will be returned.- Specified by:
encodePrimaryin classBinaryFieldInterpreter<java.lang.Double>- 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.
