      org.apache.torque.task.TorqueDataModelTask

Direct Known Subclasses:

KualiTorqueDataSQLTask, KualiTorqueSQLTask, TorqueDocumentationTask

public class TorqueDataModelTask
extends TexenTask

A base torque task that uses either a single XML schema representing a data model, or a <fileset> of XML schemas. We are making the assumption that an XML schema representing a data model contains tables for a single database.

Field Detail

xmlFile

protected String xmlFile

XML that describes the database model, this is transformed into the application model object.

filesets

protected List<org.apache.tools.ant.types.FileSet> filesets

Fileset of XML schemas which represent our data models.

dataModels

protected List<Database> dataModels

Data models that we collect. One from each XML schema file.

context

protected Context context

Velocity context which exposes our objects in the templates.

dataModelDbMap

protected Hashtable<String,String> dataModelDbMap

Map of data model name to database name. Should probably stick to the convention of them being the same but I know right now in a lot of cases they won't be.

databaseNames

protected Hashtable<String,String> databaseNames

Hashtable containing the names of all the databases in our collection of schemas.

sqldbmap

protected String sqldbmap

Name of the properties file that maps an SQL file to a particular database.

targetDatabase

private String targetDatabase

The target database(s) we are generating SQL for.

targetPackage

private String targetPackage

Target Java package to place the generated files in.
