## org.apache.cayenne.access.types
Class ByteType

    java.lang.Object
      org.apache.cayenne.access.types.ByteType

All Implemented Interfaces:
  ExtendedType

    public class ByteType

extends Object
implements ExtendedType

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

Field Summary
`protected boolean` | `widenBytes`

Constructor Summary
`ByteType(boolean widenBytes)`

Method Summary
`String` | `getClassName()` Returns a full name of Java class that this ExtendedType supports.
`Object` | `materializeObject(CallableStatement st, int index, int type)` Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.
`Object` | `materializeObject(ResultSet rs, int index, int type)` Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.
`void` | `setJdbcObject(PreparedStatement statement, Object value, int pos, int type, int precision)` Initializes a single parameter of a PreparedStatement with object value.
`boolean` | `validateProperty(Object source, String property, Object value, DbAttribute dbAttribute, ValidationResult validationResult)` Performs validation of an object property.

Methods inherited from class java.lang.Object
`clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`
