java.lang.Object
   simpleorm.properties.SPropertyMap
      simpleorm.core.SFieldMeta
         simpleorm.core.SFieldScalar
            simpleorm.core.SFieldBoolean

All known Subclasses:   simpleorm.core.SFieldBooleanChar,  simpleorm.core.SFieldBooleanBit,
SFieldBoolean
abstract public class SFieldBoolean extends SFieldScalar (Code)
Booleans are represented as Boolean.TRUE/FALSE internally. However, SQL89 does not have a concept of boolean, only strings and numbers. So these are normally mapped to strings like "Y", "N". Which representation is determined in subclasses. (The JDBC java docs are useless as always "getBoolean gets booleans...").

(The issue is with JDBC, not SimpleORM. And of course SFieldObject can always be used if really needed.)




Constructor Summary
public  SFieldBoolean(SRecordMeta meta, String columnName, SPropertyValue[] pvals)
    

Method Summary
protected  ObjectconvertDatabaseToBoolean(ResultSet rs, int sqlIndex)
    
protected  BooleanconvertExternalToBoolean(Object raw)
     Shared routine for converting Strings to booleans so all boolean implementations can be consistent.
 ObjectconvertToField(Object raw)
     Converts from the users external representation to the internal representation stored in SRecordInstance.


Constructor Detail
SFieldBoolean
public SFieldBoolean(SRecordMeta meta, String columnName, SPropertyValue[] pvals)(Code)




Method Detail
convertDatabaseToBoolean
protected Object convertDatabaseToBoolean(ResultSet rs, int sqlIndex) throws Exception(Code)
Shared routine for converting database representations to booleans so all boolean implementations can be consistent and so boolean classes can be attached to existing database columns



convertExternalToBoolean
protected Boolean convertExternalToBoolean(Object raw)(Code)
Shared routine for converting Strings to booleans so all boolean implementations can be consistent.



convertToField
Object convertToField(Object raw)(Code)
Converts from the users external representation to the internal representation stored in SRecordInstance. This is deliberately quite permissive, and should work even if the external world is a bit inconsistent.
