public interface AOMapper<T extends Entity,U>

Common interface for mapping between AO records of type T to domain objects of type U.

Since:

v5.9.5

Method Summary

java.util.Map<java.lang.String,java.lang.Object>	toAO(U model) Return a mapping of AO column names to values which will represent the domain object.
U	toModel(T record) Constructs a (usually immutable) domain object from the AO record.
void	update(U source, T target) Copies fields from a domain object to the AO record representation.

Method Detail

toAO

@NotNull
java.util.Map<java.lang.String,java.lang.Object> toAO(U model)

Return a mapping of AO column names to values which will represent the domain object.

The keys of the map must be the exact names of the columns as they will appear in AO. E.g. for a column fieldId the column name would be FIELD_ID.

Note: the ID (primary key) column does not need to be included. This is only used when persisting new domain objects to AO.

Parameters:

model - the new domain object

Returns:

a map containing the columns and values

toModel

@NotNull
U toModel(T record)

Constructs a (usually immutable) domain object from the AO record.

Parameters:

record - the record to use

Returns:

the domain object

update

void update(U source,
            T target)

Copies fields from a domain object to the AO record representation. Note that the save() method must not be called.

Parameters:

source - the domain object

target - the corresponding AO record
