Method Details

putDryRun

public void putDryRun(@Nonnull
 String entityName,
 @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)

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

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

See Also:

• 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, String, String)

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())

eventFunction - the function that generates the event to be thrown. See EntityPropertyHelper for some functions that may be used to generate events

dispatchEvent - true if the method should dispatch an event after it is run.
