Constructor Details

IndexConstantAction

protected IndexConstantAction(UUID tableId,
 String indexName,
 String tableName,
 String schemaName)

Make the ConstantAction for a CREATE/DROP INDEX statement.

Parameters:

tableId - The table uuid

indexName - Index name.

tableName - The table name

schemaName - Schema that index lives in.

Method Details

getIndexName

public String getIndexName()

Get the index name.

Returns:

the name of the index

setIndexName

public void setIndexName(String indexName)

Set the index name at execution time. Useful for unnamed constraints which have a backing index.

Parameters:

indexName - The (generated) index name.

setConstraintID

public void setConstraintID(UUID constraintID)

Set the id for the constraint which may be driving this index action. This is called by CreateConstraintConstantAction.

Parameters:

constraintID - The id of the constraint
