GemFireXDModelReader

public GemFireXDModelReader(Platform platform)

Creates a new model reader for GemFireXD databases.

Parameters:

platform - The platform that this model reader belongs to

Method Detail

isInternalForeignKeyIndex

protected boolean isInternalForeignKeyIndex(DatabaseMetaDataWrapper metaData,
                                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 DerbyModelReader

Parameters:

metaData - The database meta data

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(DatabaseMetaDataWrapper metaData,
                                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 DerbyModelReader

Parameters:

metaData - The database meta data

table - The table owning the index

index - The index to check

Returns:

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