Method Details

convertToDatabaseColumn

public Integer convertToDatabaseColumn(Boolean attribute)

Description copied from interface: AttributeConverter

Converts the value stored in the entity attribute into the data representation to be stored in the database.

Specified by:

convertToDatabaseColumn in interface AttributeConverter<Boolean,Integer>

Parameters:

attribute - the entity attribute value to be converted

Returns:

the converted data to be stored in the database column

convertToEntityAttribute

public Boolean convertToEntityAttribute(Integer dbData)

Description copied from interface: AttributeConverter

Converts the data stored in the database column into the value to be stored in the entity attribute. Note that it is the responsibility of the converter writer to specify the correct dbData type for the corresponding column for use by the JDBC driver: i.e., persistence providers are not expected to do such type conversion.

Specified by:

convertToEntityAttribute in interface AttributeConverter<Boolean,Integer>

Parameters:

dbData - the data from the database column to be converted

Returns:

the converted value to be stored in the entity attribute

toDomainValue

public Boolean toDomainValue(Integer relationalForm)

Description copied from interface: BasicValueConverter

Convert the relational form just retrieved from JDBC ResultSet into the domain form.

Specified by:

toDomainValue in interface BasicValueConverter<Boolean,Integer>

toRelationalValue

public Integer toRelationalValue(Boolean domainForm)

Description copied from interface: BasicValueConverter

Convert the domain form into the relational form in preparation for storage into JDBC

Specified by:

toRelationalValue in interface BasicValueConverter<Boolean,Integer>

getDomainJavaType

public JavaType<Boolean> getDomainJavaType()

Description copied from interface: BasicValueConverter

Descriptor for the Java type for the domain portion of this converter

Specified by:

getDomainJavaType in interface BasicValueConverter<Boolean,Integer>

getRelationalJavaType

public JavaType<Integer> getRelationalJavaType()

Description copied from interface: BasicValueConverter

Descriptor for the Java type for the relational portion of this converter

Specified by:

getRelationalJavaType in interface BasicValueConverter<Boolean,Integer>
