forBackReferences

public static JdbcIdentifierBuilder forBackReferences(JdbcConverter converter,
 AggregatePath path,
 Function<AggregatePath, Object> valueProvider)

Creates ParentKeys with backreference for the given path and value of the parents id.

forBackReference

public static Identifier forBackReference(JdbcConverter converter,
 AggregatePath path,
 Identifier defaultIdentifier,
 Function<AggregatePath, Object> valueProvider)

Parameters:

converter - used for determining the column types to be used for different properties. Must not be null.

path - the path for which needs to back reference an id. Must not be null.

defaultIdentifier - Identifier to be used as a default when no backreference can be constructed. Must not be null.

valueProvider - provides values for the Identifier based on an AggregatePath. Must not be null.

Returns:

Guaranteed not to be null.

withQualifier

public JdbcIdentifierBuilder withQualifier(AggregatePath path,
 Object value)

Adds a qualifier to the identifier to build. A qualifier is a map key or a list index.

Parameters:

path - path to the map that gets qualified by value. Must not be null.

value - map key or list index qualifying the map identified by path. Must not be null.

Returns:

this builder. Guaranteed to be not null.
