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

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

All Implemented Interfaces:
  ExtendedType

    public class ByteType

extends AbstractType

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
Author:

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 st, Object val, int pos, int type, int precision)` Calls "PreparedStatement.setObject(..)".

Methods inherited from class org.apache.cayenne.access.types.AbstractType

Method Detail

### getClassName

    public String getClassName()

  Description copied from interface: `ExtendedType`
  Returns a full name of Java class that this ExtendedType supports.

  Specified by:
    `getClassName` in interface `ExtendedType`
  Specified by:
    `getClassName` in class `AbstractType`

### materializeObject

    public Object materializeObject(ResultSet rs,
                                    int index,
                                    int type)
                             throws Exception

  Description copied from interface: `ExtendedType`
  Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.

  Specified by:
    `materializeObject` in interface `ExtendedType`
  Specified by:
    `materializeObject` in class `AbstractType`
  Throws:
    `Exception` - if read error ocurred, or an object can't be converted to a target Java class.

### materializeObject

    public Object materializeObject(CallableStatement st,
                                    int index,
                                    int type)
                             throws Exception

  Description copied from interface: `ExtendedType`
  Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.

  Specified by:
    `materializeObject` in interface `ExtendedType`
  Specified by:
    `materializeObject` in class `AbstractType`
  Throws:
    `Exception` - if read error ocurred, or an object can't be converted to a target Java class.

### setJdbcObject

    public void setJdbcObject(PreparedStatement st,
                              Object val,
                              int pos,
                              int type,
                              int precision)
                       throws Exception

  Description copied from class: `AbstractType`
  Calls "PreparedStatement.setObject(..)". Some DbAdapters may need to override this behavior for at least some of the object types, as it doesn't work consistently across all JDBC drivers.

  Specified by:
    `setJdbcObject` in interface `ExtendedType`
  Overrides:
    `setJdbcObject` in class `AbstractType`
  Throws:
    `Exception`
