eyedbodl --help
One must specify one and only one of the following major options:
--gencode=C++ Generates C++ code
--gencode=Java Generates Java code
--gencode=ODL Generates ODL
--update|-u Updates schema in database <dbname>
--diff Displays the differences between a database schema and an odl file
--checkfile Check input ODL file
--help Displays the current information
The following options must be added to the --gencode=C++ or Java option:
<odlfile>|-|-d <dbname>|--database=<dbname> Input ODL file (or - for standard input) or the database name
The following options can be added to the --gencode=C++ or Java option:
--package=<package> Package name
--output-dir=<dirname> Output directory for generated files
--output-file-prefix=<prefix> Ouput file prefix (default is the package name)
--class-prefix=<prefix> Prefix to be put at the begining of each runtime class
--db-class-prefix=<prefix> Prefix to be put at the begining of each database class
--attr-style=implicit Attribute methods have the attribute name
--attr-style=explicit Attribute methods have the attribute name prefixed by get/set (default)
--schema-name=<schname> Schema name (default is <package>)
--export Export class instances in the .h file
--dynamic-attr Uses a dynamic fetch for attributes in the get and set methods
--down-casting=yes Generates the down casting methods (the default)
--down-casting=no Does not generate the down casting methods
--attr-cache=yes Use a second level cache for attribute value
--attr-cache=no Does not use a second level cache for attribute value (the default)
For the --gencode=C++ option only
--namespace=<namespace> Define classes with the namespace <namespace>
--c-suffix=<suffix> Use <suffix> as the C file suffix
--h-suffix=<suffix> Use <suffix> as the H file suffix
--gen-class-stubs Generates a file class_stubs.h for each class
--class-enums=yes Generates enums within a class
--class-enums=no Do not generate enums within a class (default)
--gencode-error-policy=status Status oriented error policy (the default)
--gencode-error-policy=exception Exception oriented error policy
--rootclass=<rootclass> Use <rootclass> name for the root class instead of the package name
--no-rootclass Does not use any root class
The following options can be added to the --gencode=ODL option:
--system-class Generates system class ODL
The following option must be added to the --update|-u option:
-d <dbname>|--database=<dbname> Database for which operation is performed
The following options can be added to the --update|-u option:
<odlfile>|- Input ODL file or '-' (standard input)
--schema-name=<schname> Schema name (default is package)
--db-class-prefix=<prefix> Prefix to be put at the begining of each database class
--rmv-undef-attrcomp=yes|no Removes (yes) or not (no) the undefined attribute components
(constraint, index and implementation). Default is no
--update-index=yes|no Updates (yes) or not (no) the index with a different
implementation in the DB. Default is no
--rmcls={<class>} Removes the given class list
--rmsch Removes the entire schema
The following options must be added to the --diff option:
-d <dbname>|--database=<dbname> Database for which the schema difference is performed
<odlfile> The input ODL file for which the schema difference is performed
The following options can be added to the --diff option:
--system-class Performs difference on system classes also
The following option must be added to the --checkfile option:
<odlfile>|- Input ODL file or '-' (standard input)
The following options can be added when an <odlfile> is set:
--cpp=<cpp> Uses <cpp> preprocessor instead of the default one
--cpp-flags=<cpp-flags> Adds <cpp-flags> to the preprocessing command
--no-cpp Does not use any preprocessor
Common Options:
-U <user>|@, --user=<user>|@ User name
-P [<passwd>], --passwd[=<passwd>] Password
--host=<host> eyedbd host
