Constructor Detail

BooleanMapping

public BooleanMapping(DatabaseAdapter dba,
                      java.lang.Class type)

BooleanMapping

public BooleanMapping(DatabaseAdapter dba,
                      FieldMetaData fmd)
Method Detail

mapTo

public void mapTo(Column col)
Description copied from class: ColumnMapping
Links this mapping to a specific column. Linkage involves at least two steps:
  1. Calling the column's Column.mapWith(com.triactive.jdo.store.mapping.ColumnMapping) method
  2. Setting this mapping's ColumnMapping.typeInfo to match the column's

This method can be called at most once for a given mapping. Subclasses may do extra work as a consequence of mapping themselves to a column, but they should always call super.mapTo(col) first.

Overrides:
mapTo in class ColumnMapping

setBoolean

public void setBoolean(PersistenceManager pm,
                       java.sql.PreparedStatement ps,
                       int param,
                       boolean value)
Overrides:
setBoolean in class ColumnMapping

getBoolean

public boolean getBoolean(PersistenceManager pm,
                          java.sql.ResultSet rs,
                          int param)
Overrides:
getBoolean in class ColumnMapping

setObject

public void setObject(PersistenceManager pm,
                      java.sql.PreparedStatement ps,
                      int param,
                      java.lang.Object value)
Overrides:
setObject in class ColumnMapping

getObject

public java.lang.Object getObject(PersistenceManager pm,
                                  java.sql.ResultSet rs,
                                  int param)
Overrides:
getObject in class ColumnMapping

newSqlLiteral

public SqlExpression newSqlLiteral(QueryStatement qs,
                                   java.lang.Object value)
Description copied from class: Mapping
Returns an SQL expression representing the literal value of a Java object. The object must be of a type used with this mapping.

Specified by:
newSqlLiteral in class Mapping
Parameters:
qs - the surrounding query statement for the expression
value - the literal value

newSqlExpression

public SqlExpression newSqlExpression(QueryStatement.QueryColumn qsc)
Description copied from class: ColumnMapping
Returns an SQL expression representing a reference to a column in a query statement.

Specified by:
newSqlExpression in class ColumnMapping
Parameters:
qsc - the query column reference
