Examples of org.datanucleus.metadata.JoinMetaData

org.datanucleus.metadata.JoinMetaData
Secondary tables and join tables are mapped using a join condition that associates a column or columns in the secondary or join table with a column or columns in the primary table, typically the primary tables primary key columns. Column elements used for relationship mapping or join conditions specify the column name and optionally the target column name. The target column name is the name of the column in the associated table corresponding to the named column. The target column name is optional when the target column is the single primary key column of the associated table.

    public JoinMetadata newJoinMetadata()
    {
        JoinMetaData internalJoinmd = getInternal().newJoinMetaData();
        JoinMetadataImpl joinmd = new JoinMetadataImpl(internalJoinmd);
        joinmd.parent = this;
        return joinmd;
    }
