Interface IdentifierFactory

All Known Implementing Classes:

AbstractIdentifierFactory

public interface IdentifierFactory

Factory that creates immutable instances of DatastoreIdentifier. Identifiers are of a particular type. Each datastore could invent its own particular types as required, just that the ones here should be the principal types required.

Returns:

The identifier case

getNameOfIdentifierCase

java.lang.String getNameOfIdentifierCase()

Convenience method to return the name for the identifier case.

Returns:

Identifier case name

getIdentifierInAdapterCase

java.lang.String getIdentifierInAdapterCase(java.lang.String identifier)

Accessor for an identifier for use in the datastore adapter

Parameters:

identifier - The identifier name

Returns:

sqlIdentifier - The SQL identifier name

Returns:

The DatastoreIdentifier

newDatastoreContainerIdentifier

DatastoreIdentifier newDatastoreContainerIdentifier(java.lang.String identifierName)

Method to use to generate an identifier for a datastore field with the supplied name. The passed name will not be changed (other than in its case) although it may be truncated to fit the maximum length permitted for a datastore field identifier.

Parameters:
