CMIS: Check the content stream updation capability

RepositoryCapabilities interface provides getContentStreamUpdatesCapability, it returns the Content stream updatable capability. Following table summarizes the possible values.

Value	Description
none	The content stream may never be updated.
anytime	The content stream may be updated any time.
pwconly	The content stream may be updated only when checked out.

Example

                  CapabilityContentStreamUpdates capabilityContentStreamUpdates = repoInfo.getCapabilities().getContentStreamUpdatesCapability();

                  if (capabilityContentStreamUpdates == null) {

                           System.out.println("Repository is not providing any value");

                  } else if (capabilityContentStreamUpdates == CapabilityContentStreamUpdates.NONE) {

                           System.out.println("Content stream will not be updated");

                  } else if (capabilityContentStreamUpdates == CapabilityContentStreamUpdates.ANYTIME) {

                           System.out.println("Content stream can be updated at any time");

                  } else if (capabilityContentStreamUpdates == CapabilityContentStreamUpdates.PWCONLY) {

                           System.out.println("Content stream can be updated only when the document is checked out");

                  }

  } else if (capabilityContentStreamUpdates == CapabilityContentStreamUpdates.PWCONLY) {

  }

 }

}

Output

Content stream can be updated at any time
