Class BooleanType

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

public class BooleanType
extends java.lang.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 constructor. This makes possible identity comparison such as object.getBooleanProperty() == Boolean.TRUE.

Since:
1.2

Method Summary
 java.lang.String getClassName()
          Returns a full name of Java class that this ExtendedType supports.
 java.lang.Object materializeObject(java.sql.CallableStatement st, int index, int type)
          Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.
 java.lang.Object materializeObject(java.sql.ResultSet rs, int index, int type)
          Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.
 void setJdbcObject(java.sql.PreparedStatement st, java.lang.Object val, int pos, int type, int precision)
          Initializes a single parameter of a PreparedStatement with object value.
