    • Method Detail

      • normalizeQuoting

        Identifier normalizeQuoting​(Identifier identifier)
        Essentially quotes the identifier if it needs to be. Useful to apply global quoting, as well as reserved word quoting after calls to naming strategies.
        Parameters:
        identifier - The identifier for which to normalize quoting.
        Returns:
        The quoting-normalized Identifier.
      • toIdentifier

        Identifier toIdentifier​(java.lang.String text)
        Generate an Identifier instance from its simple name as obtained from mapping information.

        Note that Identifiers returned from here may be implicitly quoted based on 'globally quoted identifiers' or based on reserved words.

        Parameters:
        text - The text form of a name as obtained from mapping information.
        Returns:
        The identifier form of the name.
      • toIdentifier

        Identifier toIdentifier​(java.lang.String text,
                                boolean quoted)
        Generate an Identifier instance from its simple name as obtained from mapping information. Additionally, this form takes a boolean indicating whether to explicitly quote the Identifier.

        Note that Identifiers returned from here may be implicitly quoted based on 'globally quoted identifiers' or based on reserved words.

        Parameters:
        text - The text form of a name as obtained from mapping information.
        quoted - Is the identifier to be quoted explicitly.
        Returns:
        The identifier form of the name.
      • applyGlobalQuoting

        Identifier applyGlobalQuoting​(java.lang.String text)
        Intended only for use in handling quoting requirements for column-definition as defined by Column.columnDefinition(), JoinColumn.columnDefinition(), etc. This method should not be called in any other scenario.

        This method is needed to account for that fact that the JPA spec says that column-definition should be quoted of global-identifier-quoting is requested. Again, this is needed for spec compliance. TBH, I can not think of a argument why column-definitions should ever be *globally* quoted, but the spec is the spec. In fact the default implementation allows applications to opt-out of global-identifier-quoting affecting column-definitions.

        Parameters:
        text - The text to be (possibly) quoted
        Returns:
        The identifier form

      • isReservedWord

        boolean isReservedWord​(java.lang.String word)
        Check whether the given word represents a reserved word.
        Parameters:
        word - The word to check
        Returns:
        true if the given word represents a reserved word; false otherwise.
      • toMetaDataCatalogName

        java.lang.String toMetaDataCatalogName​(Identifier catalogIdentifier)
        Render the Identifier representation of a catalog name into the String form needed in DatabaseMetaData calls.
        Parameters:
        catalogIdentifier - The Identifier representation of a catalog name
        Returns:
        The String representation of the given catalog name
      • toMetaDataSchemaName

        java.lang.String toMetaDataSchemaName​(Identifier schemaIdentifier)
        Render the Identifier representation of a schema name into the String form needed in DatabaseMetaData calls.
        Parameters:
        schemaIdentifier - The Identifier representation of a schema name
        Returns:
        The String representation of the given schema name
      • toMetaDataObjectName

        java.lang.String toMetaDataObjectName​(Identifier identifier)
        Render the Identifier representation of an object name (table, sequence, etc) into the String form needed in DatabaseMetaData calls.
        Parameters:
        identifier - The Identifier representation of an object name
        Returns:
        The String representation of the given object name
