Method Detail

newPlanner

public FarragoSessionPlanner newPlanner(FarragoSessionPreparingStmt stmt,
                                        boolean init)

Description copied from interface: FarragoSessionPersonality

Creates a new planner.

Specified by:

newPlanner in interface FarragoSessionPersonality

Overrides:

newPlanner in class FarragoDefaultSessionPersonality

Parameters:

stmt - stmt on whose behalf planner will operate

init - whether to initialize default rules in new planner

Returns:

new planner

getSqlOperatorTable

public SqlOperatorTable getSqlOperatorTable(FarragoSessionPreparingStmt preparingStmt)

Description copied from interface: FarragoSessionPersonality

Gets the SQL operator table to use for validating a statement.

Specified by:

getSqlOperatorTable in interface FarragoSessionPersonality

Overrides:

getSqlOperatorTable in class FarragoDefaultSessionPersonality

Parameters:

preparingStmt - statement being prepared

Returns:

table of builtin SQL operators and functions to use for validation; user-defined functions are not included here

getOJRexImplementorTable

public OJRexImplementorTable getOJRexImplementorTable(FarragoSessionPreparingStmt preparingStmt)

Description copied from interface: FarragoSessionPersonality

Gets the implementation table to use for compiling a statement that uses a Java calculator.

Specified by:

getOJRexImplementorTable in interface FarragoSessionPersonality

Overrides:

getOJRexImplementorTable in class FarragoDefaultSessionPersonality

Parameters:

preparingStmt - statement being prepared

newComponentImpl

public <C> C newComponentImpl(Class<C> componentInterface)

Description copied from interface: FarragoSessionPersonality

Gets the component associated with the given Class object from the personality. If the personality does not support (or recognize) the component type, it returns null. The returned instance is guaranteed to be of type C or a subclass.

Specified by:

newComponentImpl in interface FarragoSessionPersonality

Overrides:

newComponentImpl in class FarragoDefaultSessionPersonality

Parameters:

componentInterface - the interface desired

Returns:

an implementation of componentInterface or null
