simpleorm.dataset

Class SFieldObject

java.lang.Object

simpleorm.dataset.SFieldMeta

simpleorm.dataset.SFieldScalar

simpleorm.dataset.SFieldObject

All Implemented Interfaces:

java.io.Serializable

public class SFieldObject
extends SFieldScalar

Represents columns that are not objects known to SimpleORM. No conversions are done, so this provides a direct gateway to java.sql.RecordSet.getObject. Useful for database specific data types such as PostgreSQL's GIS types, and also for the new SQL array and object types.

## Should add the JDBC object mapping property, but normally the default map is OK.

SFieldObject

public SFieldObject(SRecordMeta meta,
                    java.lang.String columnName,

Method Detail

queryFieldValue

public java.lang.Object queryFieldValue(java.sql.ResultSet rs,
                                        int sqlIndex)
                                 throws java.lang.Exception

Specidalizes abstract method to actually query a column from a result set.

Specified by:

queryFieldValue in class SFieldMeta

Throws:

java.lang.Exception

convertToDataSetFieldType

protected java.lang.Object convertToDataSetFieldType(java.lang.Object raw)
                                              throws java.lang.Exception

Description copied from class: SFieldMeta

Converts the parameter from the raw type parameter to the correct internal Object type that is stored in the data set. Returns the object if no conversion necessary. Used by SRecordInstance.setObject etc., Not getObject.

Specified by:

convertToDataSetFieldType in class SFieldMeta

Throws:

java.lang.Exception

defaultSqlDataType

public java.lang.String defaultSqlDataType()

Description copied from class: SFieldScalar

The default data type if not overriden by overrideSqlDataType. This is only called when the data type is actually needed by CREATE TABLE, ie if no sqlDataTypeOverride is specified.

Specified by:

defaultSqlDataType in class SFieldScalar

isFKeyCompatible

public boolean isFKeyCompatible(SFieldScalar field)

Description copied from class: SFieldScalar

Check if two fields can be used on both sides of a foreign key relation (same type, length, ...)

javaSqlType

public int javaSqlType()

Specified by:

javaSqlType in class SFieldScalar

Returns:

int constant from java.sql.Types, used for setting sql datatype with null values
