Constructor Detail

MappingTool

public MappingTool(JDBCConfiguration conf,
                   String action,
                   boolean meta)
Constructor. Supply configuration and action.

Method Detail

getAction

public String getAction()
The action supplied on construction.


isMetaDataAction

public boolean isMetaDataAction()
Whether the action works on metadata as well as mappings.


getSchemaAction

public String getSchemaAction()
The schema modification policy, or none. See the ACTION constants in SchemaTool. May be a comma-separated list of values. Defaults to SchemaTool.ACTION_ADD.


setSchemaAction

public void setSchemaAction(String schemaAction)
The schema modification policy, or none. See the ACTION constants in SchemaTool. May be a comma-separated list of values. Defaults to SchemaTool.ACTION_ADD.


getReadSchema

public boolean getReadSchema()
Set to true to read the entire schema before mapping. Leaving this option false saves time, but is dangerous when adding new mappings, because without full knowledge of the existing schema the mapping tool might create tables or indexes that conflict with existing components.


setReadSchema

public void setReadSchema(boolean readSchema)
Set to true to read the entire schema before mapping. Leaving this option false saves time, but is dangerous when adding new mappings, because without full knowledge of the existing schema the mapping tool might create tables or indexes that conflict with existing components.


getSequences

public boolean getSequences()
Whether to manipulate sequences. Defaults to true.


setSequences

public void setSequences(boolean seqs)
Whether to manipulate sequences. Defaults to true.


getIndexes

public boolean getIndexes()
Whether indexes on existing tables should be manipulated. Defaults to false.


setIndexes

public void setIndexes(boolean indexes)
Whether indexes on existing tables should be manipulated. Defaults to false.


getForeignKeys

public boolean getForeignKeys()
Whether foreign keys on existing tables should be manipulated. Defaults to false.


setForeignKeys

public void setForeignKeys(boolean fks)
Whether foreign keys on existing tables should be manipulated. Defaults to false.


getPrimaryKeys

public boolean getPrimaryKeys()
Whether primary keys on existing tables should be manipulated. Defaults to false.


setPrimaryKeys

public void setPrimaryKeys(boolean pks)
Whether primary keys on existing tables should be manipulated. Defaults to false.


getDropUnusedComponents

public boolean getDropUnusedComponents()
Whether schema components that are unused by any mapping will be dropped from this tool's SchemaGroup, and, depending on the schema action, from the database. Defaults to true.


setDropUnusedComponents

public void setDropUnusedComponents(boolean dropUnused)
Whether schema components that are unused by any mapping will be dropped from this tool's SchemaGroup, and, depending on the schema action, from the database. Defaults to true.


setIgnoreErrors

public void setIgnoreErrors(boolean ignoreErrors)
Whether and SQL errors should cause a failure or just issue a warning.

public boolean getIgnoreErrors()
Whether and SQL errors should cause a failure or just issue a warning.


setSchemaTool

public void setSchemaTool(SchemaTool tool)
Set the schema tool to use for schema modification.


getSchemaWriter

The stream to export the planned schema to as an XML document. If non-null, then the database schema will not be altered.


setSchemaWriter

public void setSchemaWriter(Writer schemaWriter)
The stream to export the planned schema to as an XML document. If non-null, then the database schema will not be altered.


getMappingWriter

public Writer getMappingWriter()
The stream to export the planned mappings to as an XML document. If non-null, then the mapping repository will not be altered.


setMappingWriter

public void setMappingWriter(Writer mappingWriter)
The stream to export the planned mappings to as an XML document. If non-null, then the mapping repository will not be altered.

Set the schema to use in mapping.


clear

public void clear()
Reset the internal repository. This is called automatically after every record().


record

public void record()
Records the changes that have been made to both the mappings and the associated schema, and clears the tool for further use. This also involves clearing the internal mapping repository.
