                       CodecContext context)

Decode a FieldValue as specified type.

Type Parameters:

T - the generic result type.

Parameters:

value - the FieldValue.

metadata - the metadata of the column.

type - the specified Class.

binary - if the value should be decoded by binary protocol.

context - the codec context.

Returns:

the decoded result.

Throws:

IllegalArgumentException - if any parameter is null, or value cannot be decoded.
