Constructor Summary

HsqlDbModelReader(PlatformInfo platformInfo)
Creates a new model reader for HsqlDb databases.

Method Summary

protected boolean	isInternalForeignKeyIndex(Table table, ForeignKey fk, Index index) Tries to determine whether the index is the internal database-generated index for the given foreign key. Note that only non-unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.
protected boolean	isInternalPrimaryKeyIndex(Table table, Index index) Tries to determine whether the index is the internal database-generated index for the given table's primary key. Note that only unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.
protected Table	readTable(DatabaseMetaDataWrapper metaData, Map values) Reads the next table from the meta data.

Constructor Detail

HsqlDbModelReader

public HsqlDbModelReader(PlatformInfo platformInfo)

Creates a new model reader for HsqlDb databases.

Parameters:

platformInfo - The platform specific settings

Method Detail

readTable

protected Table readTable(DatabaseMetaDataWrapper metaData,
                          Map values)
                   throws SQLException

Reads the next table from the meta data.

Overrides:

readTable in class JdbcModelReader

Parameters:

metaData - The database meta data

values - The table metadata values as defined by JdbcModelReader.getColumnsForTable()

Returns:

The table or null if the result set row did not contain a valid table

Throws:

SQLException

isInternalForeignKeyIndex

protected boolean isInternalForeignKeyIndex(Table table,
                                            ForeignKey fk,
                                            Index index)

Tries to determine whether the index is the internal database-generated index for the given foreign key. Note that only non-unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.

Overrides:

isInternalForeignKeyIndex in class JdbcModelReader

Parameters:

table - The table owning the index and foreign key

fk - The foreign key

index - The index to check

Returns:

true if the index seems to be an internal primary key one

isInternalPrimaryKeyIndex

protected boolean isInternalPrimaryKeyIndex(Table table,
                                            Index index)

Tries to determine whether the index is the internal database-generated index for the given table's primary key. Note that only unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.

Overrides:

isInternalPrimaryKeyIndex in class JdbcModelReader

Parameters:

table - The table owning the index

index - The index to check

Returns:

true if the index seems to be an internal primary key one
