Constructor Detail

OracleClobMapping

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

                         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 StringMapping

chooseColumnType

public TypeInfo chooseColumnType(Column col)

Description copied from class: ColumnMapping

Chooses an appropriate SQL type for a column based on the column's options.

Overrides:

chooseColumnType in class StringMapping

getSqlInsertionValue

public java.lang.String getSqlInsertionValue()

Description copied from class: ColumnMapping

Returns the SQL text to be included in INSERT statements when inserting a value into this mapping's column. This is usually "?" to indicate a JDBC statement parameter.

Overrides:

getSqlInsertionValue in class ColumnMapping

getSqlUpdateValue

public java.lang.String getSqlUpdateValue()

Description copied from class: ColumnMapping

Returns the SQL text to be included in UPDATE statements when updating a value in this mapping's column. This is usually "?" to indicate a JDBC statement parameter.

Overrides:

getSqlUpdateValue in class ColumnMapping

setString

public void setString(PersistenceManager pm,
                      java.sql.PreparedStatement ps,
                      int param,
                      java.lang.String value)

Overrides:

setString in class StringMapping

getString

public java.lang.String getString(PersistenceManager pm,
                                  java.sql.ResultSet rs,
                                  int param)

Overrides:

getString in class StringMapping

setObject

public void setObject(PersistenceManager pm,
                      java.sql.PreparedStatement ps,
                      int param,
                      java.lang.Object value)

Overrides:

setObject in class StringMapping

getObject

public java.lang.Object getObject(PersistenceManager pm,
                                  java.sql.ResultSet rs,
                                  int param)

Overrides:

getObject in class StringMapping

postInsert

public void postInsert(StateManager sm,
                       java.sql.Connection conn,
                       java.lang.Object value)

Description copied from interface: PostInsertProcessing

Called after a SQL INSERT has been performed.

Specified by:

postInsert in interface PostInsertProcessing

Parameters:

sm - The state manager of the instance owning the Java object being inserted.

conn - The connection on which the INSERT has been performed.

value - The column value being inserted.

postUpdate

public void postUpdate(StateManager sm,
                       java.sql.Connection conn,
                       java.lang.Object value)

Retrieve the empty CLOB locator created by the insert statement and write out the current CLOB field value to the Oracle CLOB object

Specified by:

postUpdate in interface PostUpdateProcessing

Parameters:

sm - The state manager of the instance owning the Java object being updated.

conn - The connection on which the UPDATE has been performed.

value - The column value being updated.
