public class AttributeDefImpl

extends oracle.jbo.server.DefObject

implements AttributeDef, EJBPersistable

AttributeDefImpl is an implementation class for the AttributeDef interface in the middle tier server. The main function of this class is to describe an attribute in an Entity Object or View Object.

For each Entity attribute (as well as for each View Object attribute), there is a get method to get its value and the set method to set its value. Entity Objects can have the following kinds of attributes:

• Persistent. A entity object attribute that is persisted in the database. The value of a persistent attribute can be derived from a database query.
• Transient. A entity object attribute that is not persisted in the database. The value of a transient attribute cannot be derived from a database query.

If you use the Entity Object wizard in the Business Components for Java Design Time tool to create an Entity Object based on an existing table, a persistent Entity attribute is created for each table column. After, if you change the table, you need to manually change the attribute.

Note that for a View Object attribute, there is a separate class, ViewAttributeDefImpl, that extends AttributeDefImpl.

The AttributeDefImpl class has static methods to create AttributeDefImpl instances from the Entity XML file. These instances can also be created programmatically. For example, the method addDynamicAttribute creates a dynamic attribute (AttributeDefImpl) on the View Object.

Advanced users can provide their own implementation of EntityDefImpl (by subclassing EntityDefImpl). Within it, they can create their own AttributeDefImpls by using:

 new AttributeDefImpl(...);

getOIDAttrNames

public java.lang.String[] getOIDAttrNames()

Internal: Applications should not use this method.

getObjectType

public java.lang.String getObjectType()

If the attribute is an object, returns the name of the attribute's object type

For example, assume that you have created an Employee table that contains an Address object of type address_t. The SQL code would look like this:

 CREATE TYPE address_t AS OBJECT  -- user defined Oracle Object datatype
        (
        Street VARCHAR2(30),
        City VARCHAR2(25),
        State CHAR(2),
        Zip  Number
        );

 CREATE TABLE Employee
        (
        EmpId Number,
        Name VARCHAR2(30),
        Address address_t,  -- note the Oracle Object datatype
        );
 

In an Employee Entity Object, this would be interpreted as an Address attribute of type Address_t. If this method were applied to the Address attribute, it would return Address_t.

Returns:

the name of the type.

getPrecision

public int getPrecision()

Gets the attribute's precision.

Scale value is meaningful only for numeric attributes.

Specified by:

getScale in interface AttributeDef

Returns:

the scale value, or 0 if unspecified.

getEntityDef

public EntityDefImpl getEntityDef()

Specified by:

getSQLType in interface AttributeDef

Returns:

the data type. For JDBC types, returns a value of java.sql.Types. For Oracle JDBC types, returns a value of oracle.jdbc.driver.OracleTypes.

getAttributeKind

public byte getAttributeKind()

Returns the "kind" enumerations of this attribute. The "kind" of enumeration can be either persistent, derived, row-associated, transient, or dynamic.

The following code snippet uses this method to return the attribute kind for each element in an array of AttributeDefs. Some processing is then done based on the results.

 for(int i=0; i < attributeDefs.length; i++)
 {
    byte attrKind=attributeDefs[i].getAttributeKind();
    if(attrKind==AttributeDef.ATTR_ASSOCIATED_ROW  ||
      attrKind==AttributeDef.ATTR_ASSOCIATED_ROWITERATOR)
      {
        do some processing
      }
  }
 

Specified by:

getAttributeKind in interface AttributeDef

Returns:

one of ATTR_PERSISTENT, ATTR_SQL_DERIVED, ATTR_ASSOCIATED_ROW, ATTR_TRANSIENT or ATTR_DYNAMIC.

getAttrLoad

public byte getAttrLoad()

Describes the manner in which the data for this attribute is loaded from database.

In the typical case, after the View Object query is executed, the framework retrieves data from the query result and populates the Entity row with the attribute values.

The framework uses two different ways to retrieve data from the query result. The first is the normal SQL SELECT way--the column corresponding to the attribute is accessible in the query result. For example, if the View Object query says SELECT e.Empno, e.Ename, e.Job, FROM Emp then attributes corresponding to columns Empno, Ename, and Job are accessible from the query result. That is, one can do result.getObject("Empno") to JDBC to retrieve the data. This situation is described as by the getAttrLoad() return value ATTR_LOAD_EACH.

If the query is over an Oracle Object table, on the other hand, the framework doesn't have access to individual columns from the query result. For example, assume an object table OBJEMP is based on an object type T, and this type has attributes Name, Address, and Job.

The query statement that the framework builds for such a table is select value(o) from TAB o. This retrieves each row from the table as an Oracle Object. From JDBC, the framework gets this as an object (STRUCT) and gets attributes out of the STRUCT.

In this case, the Entity Object attributes will have the following attribute load values:

    Name    -- ATTR_LOAD_BULK
    Address -- ATTR_LOAD_SKIP
    Job     -- ATTR_LOAD_SKIP
 

ATTR_LOAD_BULK on Name means that while the framework retrieves data for Name, data for the other attributes, Address and Job is bulk-retrieved as well. ATTR_LOAD_SKIP on Address and Job means that since the framework filled in Address and Job while it retrieved Name, they should be skipped since they were bulk-retrieved with Name.

Returns:

the load value. Can be one of ATTR_LOAD_BULK, ATTR_LOAD_SKIP, or ATTR_LOAD_EACH.

getJavaType

public java.lang.Class getJavaType()

Returns the Java type of the attribute.

For example, if the attribute is of type String, this method returns java.lang.String; if it is of type Number, it returns oracle.jbo.domain.Number.

Subclasses should override this method because Entities without accessors should also be able to get their types from attribute descriptors and beans.

Specified by:

getJavaType in interface AttributeDef

Returns:

the attribute's Java class, or Object for attributes which have no accessor methods available.

getElemType

public java.lang.Class getElemType()

Returns the element type of the attribute.

For VARRAYs, this method returns the class name of the elements that are in the VARRAY.

Element type is relevant only if the attribute is an array attribute.

Returns:

the attribute's element class, or null if the attribute is not an array attribute.

getDefaultValue

public java.lang.Object getDefaultValue()

Returns the default value of the attribute.

The default value for an attribute is expressed in terms of the Java type system, rather than the storage type system.

Returns:

the default value for the attribute, or null if none.

getColumnName

public java.lang.String getColumnName()

Returns the column name to which this attribute is mapped.

Specified by:

getColumnName in interface AttributeDef

Returns:

the database column name of this attribute.

getColumnNameForQuery

public java.lang.String getColumnNameForQuery()

Returns the column name to be used in query statement.

For Entity Object attributes, this is the same as the column name returned by getColumnName (that is, the name of the column to which the attribute is mapped).

For View Object attributes, the value it returns depends on whether the query was created in expert mode:

• if expert mode, it returns the column alias.
• if non-expert mode, it returns eo-usage-name.column-name.

Specified by:

getColumnNameForQuery in interface AttributeDef

Returns:

the column name to be used in query.

convertToJava

public java.lang.Object convertToJava(java.lang.Object data)
                               throws DataCreationException
