Retrieve an IContentManager
The IPortalContext has an IContentManagerFactory which can be used to create an IContentManager. To retrieve an IContentManager based on a connection, see the following code snippet for an example:
...
Which connectionName to use depends on your project's configuration.
Creating new content
The following code snippet shows how to create new content based on a given string.
...
The properties object may be used to store additional properties with the content. The contentId will be required to read, update or delete this content at a later time.
Read metadata
To retrieve file metadata, including custom properties, you may use the readMetadata method, for example:
| Code Block | ||
|---|---|---|
| ||
IContentMetadata metadata = contentManager.readMetadata(contentId, context.getSessionScope().getActiveUser(), true);
IValue propertyValue = metadata.getProperties().getProperty("customProperty"); |
Read content
The following code snippet shows how to retrieve the string that was created in the previous example.
...
| Code Block | ||
|---|---|---|
| ||
InputStream stream = new ByteArrayInputStream(newContentString.getBytes("UTF-8"));
IUserData userData = context.getSessionScope().getActiveUser();
CustomContentProperties properties = new CustomContentProperties();
properties.setProperty("customProperty", new StringValue("newValue"));
String contentName = "new content name";
String contentType = "text/plain";
Long processId = null;
String caseId = null;
if(contentManager instanceof IChannelContentManager channelContentManager) {
// Using the Java NIO-based API introduced in Blueriq 17.4
contentManager.update(contentId, Channels.newChannel(stream), contentName, contentType, processId, caseId, properties, userData);
} else {
// Using the stream-based API that was deprecated in Blueriq 17.4 and might be released in a future release
contentManager.update(contentId, stream, contentName, contentType, processId, caseId, properties, userData);
} |
Delete content
The following example shows how to delete the content made in the previous example:
| Code Block | ||
|---|---|---|
| ||
contentManager.delete(contentId); |
Move content
The following example shows how to move content between content managers:
| Code Block | ||
|---|---|---|
| ||
// Get the active user data IUserData userData = context.getSessionScope().getActiveUser(); // Pre-emptive check if the both content managers are the of the same implemation so we can check if can move the files. // This is should also be done in the move function of the IContentManager. if (!sourceContentManager.getImplementation().getClass().equals(targetImplementation.getImplementation().getClass())) { // Both content managers require the same implementation to perform a direct move. return null; } GUID GUID newContentId = sourceContentManager.move(targetContentManager, contentId, userData); } |
