Method Summary

Modifier and TypeMethod and Description
public int
getPriority(Class<? extends DatabaseObject>
The object type we are asked to snapshot
objectType, Database
The DBMS for which the snapshotting should be done
database)

Overrides liquibase.snapshot.jvm.JdbcSnapshotGenerator.getPriority.

Implements liquibase.snapshot.SnapshotGenerator.getPriority.

Inquire if this SnapshotGenerator is capable of snapshotting objects of type objectType (e.g. Table, Index, View etc.) in the DBMS database (e.g. Oracle, Postgres, HyperSQL etc.) A return priority of > 0 will be interpreted as capable.

protected DataType
readDataType(CachedRow
the result from the JDBC getColumns() call for the column
columnMetadataResultSet, Column
logical definition of the column (object form)
column, Database
the database from which the column originates
database)

Overrides liquibase.snapshot.jvm.ColumnSnapshotGenerator.readDataType.

Processes metadata of a column, e.g. name, type and default value.

public Class<? extends SnapshotGenerator>[]
replaces()

Overrides liquibase.snapshot.jvm.JdbcSnapshotGenerator.replaces.

Implements liquibase.snapshot.SnapshotGenerator.replaces.

Returns classes (and superclasses) that this SnapshotGenerator replaces.

public int getPriority(Class<? extends DatabaseObject> objectType, Database database)

Overrides liquibase.snapshot.jvm.JdbcSnapshotGenerator.getPriority.

Implements liquibase.snapshot.SnapshotGenerator.getPriority.

Doc from liquibase.snapshot.SnapshotGenerator.getPriority.

Inquire if this SnapshotGenerator is capable of snapshotting objects of type objectType (e.g. Table, Index, View etc.) in the DBMS database (e.g. Oracle, Postgres, HyperSQL etc.) A return priority of > 0 will be interpreted as capable. The highest priority for an objectType-database combination wins.

Parameters
objectType:Class<? extends DatabaseObject>

The object type we are asked to snapshot

database:Database

The DBMS for which the snapshotting should be done

Returns:int

An integer of PRIORITY_... constants indicating our capability and willingness to snapshot

protected DataType readDataType(CachedRow columnMetadataResultSet, Column column, Database database)

Overrides liquibase.snapshot.jvm.ColumnSnapshotGenerator.readDataType.

Doc from liquibase.snapshot.jvm.ColumnSnapshotGenerator.readDataType.

Processes metadata of a column, e.g. name, type and default value. We start with the result of the JDBC DatabaseMetaData.getColumns() method. Depending on Database, additional columns might be present.

Parameters
columnMetadataResultSet:CachedRow

the result from the JDBC getColumns() call for the column

column:Column

logical definition of the column (object form)

database:Database

the database from which the column originates

Returns:DataType

a DataType object with detailed information about the type

Implements liquibase.snapshot.SnapshotGenerator.replaces.

Doc from liquibase.snapshot.SnapshotGenerator.replaces.

Returns classes (and superclasses) that this SnapshotGenerator replaces. Return null or empty array to not affect the SnapshotGeneratorChain.
