Method Detail

getExpectedJavaType

protected int getExpectedJavaType()

Description copied from class: MaxEmbeddedLobFieldStrategy

Return the expected type of the field from JavaTypes or JavaSQLTypes.

Specified by:

getExpectedJavaType in class MaxEmbeddedLobFieldStrategy

update

protected void update(OpenJPAStateManager sm,
                      Row row)
               throws SQLException

Description copied from class: MaxEmbeddedLobFieldStrategy

Set the value of the owning field into the given row.

Specified by:

update in class MaxEmbeddedLobFieldStrategy

Throws:

SQLException

isCustom

protected Boolean isCustom(OpenJPAStateManager sm,
                           JDBCStore store)

Description copied from class: MaxEmbeddedLobFieldStrategy

Return whether this is a custom insert/update.

Specified by:

isCustom in class MaxEmbeddedLobFieldStrategy

putData

protected void putData(OpenJPAStateManager sm,
                       ResultSet rs,
                       DBDictionary dict)
                throws SQLException

Description copied from class: MaxEmbeddedLobFieldStrategy

Set the data from the given state manager into the result set.

Specified by:

putData in class MaxEmbeddedLobFieldStrategy

Throws:

SQLException

map

public void map(boolean adapt)

Description copied from interface: Strategy

Map the owning mapping using this strategy.

Specified by:

map in interface Strategy

Overrides:

map in class MaxEmbeddedLobFieldStrategy

Parameters:

adapt - if true, use the owning mapping's raw mapping info to set its ORM data; if false, ORM data will already be set

initialize

public void initialize()

Description copied from interface: Strategy

Perform caching and other initialization operations. This method is called after Strategy.map(boolean), and after all related components have been mapped as well.

Specified by:

initialize in interface Strategy

Overrides:

initialize in class AbstractStrategy
