Class BooleanType

java.lang.Object
  extended by org.apache.cayenne.access.types.BooleanType
All Implemented Interfaces:
ExtendedType

public class BooleanType
extends Object
implements ExtendedType

Handles java.lang.Boolean mapping. Note that "materialize*" methods return either Boolean.TRUE or Boolean.FALSE, instead of creating new Boolean instances using contructor. This makes possible identity comparison such as object.getBooleanProperty() == Boolean.TRUE.

Since:
1.2

Constructor Summary
BooleanType()
           
 
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)
          Initializes a single parameter of a PreparedStatement with object value.
 boolean validateProperty(Object source, String property, Object value, DbAttribute dbAttribute, ValidationResult validationResult)
          Deprecated. since 3.0 as validation should not be done at the DataNode level.

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

validateProperty

public boolean validateProperty(Object source,
                                String property,
                                Object value,
                                DbAttribute dbAttribute,
                                ValidationResult validationResult)
Deprecated. since 3.0 as validation should not be done at the DataNode level.

Description copied from interface: ExtendedType
Performs validation of an object property. Property is considered valid if this it satisfies the database constraints known to this ExtendedType. In case of validation failure, failures are appended to the ValidationResult object and false is returned.

Specified by:
validateProperty in interface ExtendedType

setJdbcObject

public void setJdbcObject(PreparedStatement st,
                          Object val,
                          int pos,
                          int type,
                          int precision)
                   throws Exception
Description copied from interface: ExtendedType
Initializes a single parameter of a PreparedStatement with object value.

Specified by:
setJdbcObject in interface ExtendedType
Throws:
Exception

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
Throws:
Exception - if read error ocurred, or an object can't be converted to a target Java class.

materializeObject

                         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
Throws:
Exception - if read error ocurred, or an object can't be converted to a target Java class.
