      Parameters:

  • Method Details

    • setDatabasePlatform

      public void setDatabasePlatform(DatabasePlatform databasePlatform)
      Description copied from interface: NamingConvention
      Set the associated DatabasePlaform.

      This is set after the DatabasePlatform has been associated.

      The purpose of this is to enable NamingConvention to be able to support database platform specific configuration.

      Specified by:
      setDatabasePlatform in interface NamingConvention
      Parameters:
      databasePlatform - the database platform

    • getSequenceName

      public String getSequenceName(String rawTableName, String pkColumn)
      Description copied from interface: NamingConvention
      Return the sequence name given the table name (for DB's that use sequences).

      Typically you might append "_seq" to the table name as an example.

      Specified by:
      getSequenceName in interface NamingConvention
      Parameters:
      rawTableName - the table name
      Returns:
      the sequence name

    • getCatalog

      public String getCatalog()
      Return the catalog.

    • setCatalog

      public void setCatalog(String catalog)
      Sets the catalog.

    • getSchema

      public String getSchema()
      Return the schema.

    • setSchema

      public void setSchema(String schema)
      Sets the schema.

    • getSequenceFormat

      public String getSequenceFormat()
      Returns the sequence format.

    • setSequenceFormat

      public void setSequenceFormat(String sequenceFormat)
      Set the sequence format used to generate the sequence name.

      The format should include "{table}". When generating the sequence name {table} is replaced with the actual table name.

      Parameters:
      sequenceFormat - string containing "{table}" which is replaced with the actual table name to generate the sequence name.

    • isUseForeignKeyPrefix

      public boolean isUseForeignKeyPrefix()
      Return true if a prefix should be used building a foreign key name.

      This by default is true and this works well when the primary key column names are simply "ID". In this case a prefix (such as "ORDER" and "CUSTOMER" etc) is added to the foreign key column producing "ORDER_ID" and "CUSTOMER_ID".

      This should return false when your primary key columns are the same as the foreign key columns. For example, when the primary key columns are "ORDER_ID", "CUST_ID" etc ... and they are the same as the foreign key column names.

      Specified by:
      isUseForeignKeyPrefix in interface NamingConvention

    • setUseForeignKeyPrefix

      public void setUseForeignKeyPrefix(boolean useForeignKeyPrefix)
      Set this to false when the primary key columns matching your foreign key columns.

    • getTableName

      public TableName getTableName(Class<?> beanClass)
      Returns the table name for a given entity bean.

      This first checks for the @Table annotation and if not present uses the naming convention to define the table name.

      Specified by:
      getTableName in interface NamingConvention
      Parameters:
      beanClass - the bean class
      Returns:
      the table name for the entity class
      See Also:
      • getTableNameFromAnnotation(Class)
      • getTableNameByConvention(Class)

    • getM2MJoinTableName

      public TableName getM2MJoinTableName(TableName lhsTable, TableName rhsTable)
      Description copied from interface: NamingConvention
      Returns the ManyToMany join table name (aka the intersection table).
      Specified by:
      getM2MJoinTableName in interface NamingConvention
      Parameters:
      lhsTable - the left hand side bean table
      rhsTable - the right hand side bean table
      Returns:
      the many to many join table name

    • deriveM2MColumn

      public String deriveM2MColumn(String tableName, String dbColumn)

      Description copied from interface: NamingConvention
      Return the full table name taking into account quoted identifiers.
      Specified by:

      Load settings from properties.
