Constructor Detail

OracleBlobRDBMSMapping

public OracleBlobRDBMSMapping(JavaTypeMapping mapping,
                              StoreManager storeMgr,
                              DatastoreField field)

Constructor.

Parameters:

mapping - The Java mapping

storeMgr - Store Manager in use

field - The column in the datastore

OracleBlobRDBMSMapping

protected OracleBlobRDBMSMapping(StoreManager storeMgr,
                                 JavaTypeMapping mapping)

Creates a OracleBlobRDBMSMapping

Parameters:

storeMgr - Store Manager

mapping - The Java mapping

Method Detail

getInsertionInputParameter

public java.lang.String getInsertionInputParameter()

Description copied from class: RDBMSMapping

Accessor for the string to put in any retrieval datastore statement for this field. In RDBMS, this is typically a ? to be used in JDBC statements.

Overrides:

getInsertionInputParameter in class ColumnMapping

Returns:

The input parameter

See Also:

RDBMSMapping.getInsertionInputParameter()

getObject

public java.lang.Object getObject(java.lang.Object rs,
                                  int param)

Returns the object to be loaded from the Orale BLOB.

Specified by:

getObject in interface DatastoreMapping

Overrides:

getObject in class RDBMSMapping

Parameters:

rs - the ResultSet from the query

param - the index in the query

Returns:

the object loaded as a byte[]

Throws:

javax.jdo.JDODataStoreException

getTypeInfo

public TypeInfo getTypeInfo()

Description copied from class: ColumnMapping

Returns the TypeInfo (JDBC SQL type) for columns. This method is capable of returning only one TypeInfo (SQL Type). In that way, it seems adequate for using in 1 column Mapping or many columns that share the same TypeInfo. However adequate in most of uses, Mappings using two or more columns should overwrite the initTypeInfo method to appropriate set differents TypeInfo (SQL type) for all the columns

Specified by:

getTypeInfo in class ColumnMapping

Returns:

The TypeInfo

See Also:

RDBMSMapping.getTypeInfo()

getUpdateInputParameter

public java.lang.String getUpdateInputParameter()

Description copied from class: RDBMSMapping

Accessor for the string to put in any update datastore statements for this field. In RDBMS, this is typically a ? to be used in JDBC statements.

Overrides:

getUpdateInputParameter in class ColumnMapping

Returns:

The input parameter.

See Also:

RDBMSMapping.getUpdateInputParameter()

includeInSQLFetchStatement

public boolean includeInSQLFetchStatement()

Whether to include this mapping in a fetch statement.

Returns:

Whether to include it when fetching the object
