putDryRun

public void putDryRun(@Nonnull
                      String entityName,
                      @Nonnull
                      Long entityId,
                      @Nonnull
                      String key,
                      String json)

Description copied from interface: JsonEntityPropertyManager

Performs all of the validation that would be performed during a JsonEntityPropertyManager.put(String, Long, String, String) request, but does not actually store the value.

Specified by:

putDryRun in interface JsonEntityPropertyManager

Parameters:

entityName - as for JsonEntityPropertyManager.put(String, Long, String, String)

entityId - as for JsonEntityPropertyManager.put(String, Long, String, String)

key - as for JsonEntityPropertyManager.put(String, Long, String, String)

json - as for JsonEntityPropertyManager.put(String, Long, String, String)

JsonEntityPropertyManager.put(String, Long, String, String)

put

public void put(@Nonnull
                String entityName,
                @Nonnull
                Long entityId,
                @Nonnull
                String key,
                String json)

Description copied from interface: JsonEntityPropertyManager

Set the value for an entity property, creating, updating, or deleting it as necessary.

Specified by:

put in interface JsonEntityPropertyManager

Parameters:

entityName - the entity name for the property (maximum length 255). As explained in the class documentation, this value should be unique to the service creating the properties and will generally not be the same as the entity to which the properties are attached.

entityId - the entity ID for the property. In general, this will be the same as the ID of the owning entity; for example, the RemoteVersionLinkService uses the version ID for this value.

key - the key for the property (maximum length 255). This value should generally be suitable for a reverse lookup when the same data might be associated with multiple entities. For example, the RemoteVersionLinkService uses the global ID of the remote object, which is the same identifier used by applinks to identify a Confluence page, Bamboo project, etc.

json - the new value for the property, or null to delete it (maximum length is available by calling JsonEntityPropertyManager.getMaximumValueLength())

JsonEntityPropertyManager.putDryRun(String, Long, String, String)

Description copied from interface: JsonEntityPropertyManager

Produces a list of entity property keys that match the provided entity name and key prefix. This convenience method is exactly equivalent to:

     JsonEntityPropertyManager.query().entityName(entityName)
          .keyPrefix(keyPrefix)
          .findDistinctKeys()
 

Specified by:

keyPrefix - the prefix to apply for limiting which keys are returned; must not be null or a blank string

Returns:

the list of distinct matching keys, sorted in ascending alphabetical order

findKeys

@Nonnull
public List<String> findKeys(@Nonnull
                                     String entityName,
                                     @Nonnull
                                     Long entityId)

Description copied from interface: JsonEntityPropertyManager

Produces a list of entity property keys that match the provided entity name and entity id. This convenience method is exactly equivalent to:

     JsonEntityPropertyManager.query().entityName(entityName)
          .entityId(entityId)
          .EntityPropertyQuery.ExecutableQuery.findKeys()
 

Specified by:

findKeys in interface JsonEntityPropertyManager

Parameters:

entityName - the entity name for the entities that are associated with the properties.

entityId - the id of the entity.

exists

public boolean exists(@Nonnull
                      String entityName,
                      @Nonnull
                      Long entityId,
                      @Nonnull
                      String key)

Description copied from interface: JsonEntityPropertyManager

Returns whether or not a given property exists. This convenience method is equivalent to JsonEntityPropertyManager.get(String, Long, String) != null, but does not actually retrieve the JSON data from the database, so it may have better performance characteristics when the JSON content is not needed.

Specified by:

exists in interface JsonEntityPropertyManager

Parameters:

entityId - the entity ID for the property

key - the key for the property

Counts the number of properties that match the given entity. This convenience method is exactly equivalent to:

     JsonEntityPropertyManager.query().entityName(entityName)
          .entityId(entityId)
          .count()
 

Specified by:

countByEntity in interface JsonEntityPropertyManager
