Constructor Detail

AbstractRemoteEntityLinkService

protected AbstractRemoteEntityLinkService(String entityName,
                                          JsonEntityPropertyManager jsonEntityPropertyManager)

Super-constructor for all remote entity link services that use JSON entity properties for storage.

Parameters:

entityName - the entity name that should be used when storing the JSON properties for this link service. this MUST be unique to the service. To reduce the risk of collision, it SHOULD NOT be the same as the name of the entity itself. For example, RemoteVersionLinkService uses "RemoteVersionLink", not "Version".

jsonEntityPropertyManager - the injected JsonEntityPropertyManager component

Method Detail

getEntityPropertyValue

@Nullable
protected String getEntityPropertyValue(@Nonnull
                                                 Long entityId,
                                                 @Nonnull
                                                 String globalId)

Retrieve the stored JSON for an entity link.

Parameters:

entityId - the ID of the specific entity that this remote entity link was stored against

globalId - the global ID against which the entity link was stored. See the return value of putEntityPropertyValue(Long, String, String) for more information.

Returns:

the stored JSON, or null if the remote entity link does not exist

putEntityPropertyValue

@Nonnull
protected String putEntityPropertyValue(@Nonnull
                                                Long entityId,
                                                @Nullable
                                                String globalId,
                                                @Nonnull
                                                String json)

Store JSON data representing an entity link.

Parameters:

entityId - the ID of the specific entity that this remote entity link will be stored against

globalId - the global ID against which to store the remote entity link, or null. If it is null, then the supplied json value is examined to see if it is a valid JSON object with a value specified for RemoteEntityLink.GLOBAL_ID generate a new unique identifier to serve as the global ID

json - the content to be stored

Returns:

the global ID used to store the link. If the supplied JSON is an an object that contains a string field called at its top level, then that value will be extracted and used as the global ID for storage. Otherwise, a global ID will be generated by this method and returned in its place.

Throws:

FieldTooLongJsonPropertyException - if globalId or json exceeds the maximum allowed length

InvalidJsonPropertyException - if json is malformed

IllegalArgumentException - if entityId or json is null

putEntityPropertyDryRun

protected String putEntityPropertyDryRun(@Nonnull
                                         Long entityId,
                                         @Nullable
                                         String globalId,
                                         @Nonnull
                                         String json)

Verifies the same conditions that putEntityPropertyValue(Long, String, String) would without actually creating or updating the property value. This is intended for use when validating a service request.

Parameters:

entityId - as for putEntityPropertyValue(Long, String, String)

globalId - as for putEntityPropertyValue(Long, String, String)

json - as for putEntityPropertyValue(Long, String, String)

Returns:

the global ID that would have been used to store the link. If this method is used to perform validation, then this value may be passed in as the globalId parameter in the following call to putEntityPropertyValue(Long, String, String) to guarantee that the same value will be used even if it is a generated UUID.

Throws:

FieldTooLongJsonPropertyException - if globalId or json exceeds the maximum allowed length

InvalidJsonPropertyException - if json is malformed

IllegalArgumentException - if entityId or json is null

verifyNotNull

protected static void verifyNotNull(ErrorCollection errors,
                                    I18nHelper i18n,
                                    String field,
                                    Object value)

verifyNotBlank

protected static void verifyNotBlank(ErrorCollection errors,
                                     I18nHelper i18n,
                                     String field,
