public class NumericBooleanType
extends BooleanType

Maps interger database values to boolean java values. Zero is considered false; NULL maps to BooleanType.getDefaultValue(); any other value is considered true.

Constructor Detail

NumericBooleanType

public NumericBooleanType()
Method Detail

getName

public String getName()
Returns the abbreviated name of the type.

This type's name is numeric_boolean

Specified by:
getName in interface Type
Overrides:
getName in class BooleanType
Returns:
String the Hibernate type name

get

public Object get(ResultSet rs,
                  String name)
           throws SQLException
Get a column value from a result set, without worrying about the possibility of null values. Called from NullableType.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.SessionImplementor, java.lang.Object) after nullness checks have been performed.

Overrides:
get in class BooleanType
Parameters:
rs - The result set from which to extract the value.
name - The name of the value to extract.
Returns:
The extracted value.
Throws:
SQLException - Indicates problem making the JDBC call(s).

set

public void set(PreparedStatement st,
                Object value,
                int index)
         throws SQLException
Set a parameter value without worrying about the possibility of null values. Called from NullableType.nullSafeSet(java.sql.PreparedStatement, java.lang.Object, int, boolean[], org.hibernate.engine.SessionImplementor) after nullness checks have been performed.

Overrides:
set in class BooleanType
Parameters:
st - The statement into which to bind the parameter value.
value - The parameter value to bind.
index - The position or index at which to bind the param value.
Throws:
SQLException - Indicates problem making the JDBC call(s).

objectToSQLString

public String objectToSQLString(Object value,
                                Dialect dialect)
                         throws Exception
String representation of the value, suitable for embedding in an SQL statement.

Specified by:
objectToSQLString in interface LiteralType
Overrides:
objectToSQLString in class BooleanType
Returns:
String the value, as it appears in a SQL query
Throws:
Exception

sqlType

public int sqlType()
A convenience form of NullableType.sqlTypes(org.hibernate.engine.Mapping), returning just a single type value since these are explicitly dealing with single column mappings.

Overrides:
sqlType in class BooleanType
Returns:
The Types mapping value.
