Class ByteType
java.lang.Object
org.apache.cayenne.access.types.ByteType
- All Implemented Interfaces:
- ExtendedType<Byte>
public class ByteType extends Object implements ExtendedType<Byte>
Handles 
java.lang.Byte type mapping. Can be configured to recast
 java.lang.Byte to java.lang.Integer when binding values to PreparedStatement. This is a
 workaround for bugs in certain drivers. Drivers that are proven to have issues with
 byte values are Sybase and Oracle (Mac OS X only).- Since:
- 1.0.3

Method SummaryModifier and Type Method Description StringgetClassName()Returns a full name of Java class that this ExtendedType supports.BytematerializeObject(CallableStatement st, int index, int type)Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.BytematerializeObject(ResultSet rs, int index, int type)Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.voidsetJdbcObject(PreparedStatement statement, Byte value, int pos, int type, int precision)Initializes a single parameter of a PreparedStatement with object value.StringtoString(Byte value)Converts value of the supported type to a human-readable String representation.
