## Connecting to a CMIS repository (the simple way)
# To be able to do anything useful on a CMIS repository, you must first find a repository, and create a session with it:

atom_url = "http://localhost:8181/alfresco/service/cmis"
user = "admin"
password = "admin"
@session = CMIS::create_session(atom_url, user, password)

# Most CMIS servers only provides one repository by default that you can connect to and the code above automatically connects to the first repository that it finds.
# If you want to connect to a specific repository you can do it like this:

available_repos = CMIS::repositories(atom_url, user, password)
puts "Trying to connect to repository with id #{available_repos[0].id}"
@session = CMIS::create_session(atom_url, user, password, available_repos[0].id)

## Working with folders and documents

### Finding the contents of the root folder

root = @session.root_folder
children = root.children

children.each do |o|
  puts o.name # Prints out all children objects found in the root folder 
end

### Creating folders

# Create a folder the simple way. This is a convenient method implemented in the JRuby CMIS library.
root.create_cmis_folder("My new folder")

# Create a folder the hard way:
folder_props = { CMIS::PropertyIds::OBJECT_TYPE_ID => "cmis:folder", CMIS::PropertyIds::NAME => "Another folder" }
root.create_folder(folder_props)

## Creating/Uploading documents

### Create a document object the simple way. This is a convenient method implemented in the JRuby CMIS Library.

# This method takes a name and a file path and uploads the file to the repository. The document will be saved as a major version.
id = root.create_cmis_document("cmis_logo.png", "/Users/ricn/cmis_logo.png")
doc = @session.get_object(id)
puts doc.name

### Create a document object the hard way:
# TODO

### Download a document to your local disk:
# TODO

### Updating a document
id = root.create_cmis_document("cmis_logo_original.png", "/Users/ricn/cmis_logo.png")
doc = @session.get_object(id)
puts "Original name: #{doc.name}"
props = { CMIS::PropertyIds::NAME => "cmis_logo_renamed.png"}
id = doc.update_properties(props)
doc = @session.get_object(id)
puts "New name: #{doc.name}"

### Deleting a document
doc = @session.get_object(id)
doc.delete # Yay, that was easy!

### Deleting a folder tree

# First we need to create a folder tree
folder1 = root.create_cmis_folder("folder1")
folder11 = folder1.create_cmis_folder("Folder11")
folder12 = folder1.create_cmis_folder("Folder12")
# Delete it
folder1.delete_tree(true, CMIS::UnfileObject::DELETE, true) # parameter explanation: boolean allversions, UnfileObject unfile, boolean continueOnFailure

## CMIS Properties

### Displaying the properties of an Object
props = @session.root_folder.properties
props.each do |p|
  display_name = p.definition.display_name
  value = p.value_as_string
  if display_name != nil && value != nil
    puts p.definition.display_name + ": " + p.value_as_string
  end
end

### Getting a property explicitly
# Each object type has a known set of properties, and you can retrieve these explicitly.
# For example, the document type has a set of properties described by the DocumentProperties 
# (http://chemistry.apache.org/java/0.8.0/maven/apidocs/org/apache/chemistry/opencmis/client/api/DocumentProperties.html) interface, 
# and you can use the methods on this interface to retrieve the value a property

# For root folder
puts "Is root folder? " + root.is_root_folder.to_s
puts "Path: " + root.path

# For a document
id = root.create_cmis_document("cmis_logo_original.png", "/Users/ricn/cmis_logo.png")
doc = @session.get_object(id)
puts "Name: " + doc.name
puts "Version label: " + doc.version_label
puts "Content stream file name: " + doc.content_stream_file_name
puts "Content stream mime type: " + doc.content_stream_mime_type

## Working with CMIS Queries. NOT WORKING :-(

query = "SELECT * FROM cmis:document WHERE cmis:name LIKE 'cmis%'"
q = @session.query(query, false) # true means search all versions

q.each do |result|
  puts result.property_value_by_query_name("cmis:name").inspect
end
