    PCCViewer. Comment

    new Comment(comment, conversation)

    The constructor for a Comment Object. This describes the comments that belong to a mark PCCViewer.Conversation.

    It will not be necessary to create comments directly with this constructor. Rather, simply use PCCViewer.Conversation#addComment.

    Note: Comment text is not sanitized in any way by the API, and will exist as the same string value assigned to it. To ensure security of the web application, text data may need to be sanitized and safely inserted into the DOM when it is used.

    Parameters:

    Name Type Description
    comment string

    The text content of the comment.

    conversation PCCViewer.Conversation

    The PCCViewer.Conversation Object that this comment belongs to.

    Throws:

    • If commentText is not a string.

      Type
      Error

    • If conversation is not a PCCViewer.Conversation Object.

      Type
      Error

    Example

    // assume we already have a PCCViewer.Mark object created
var conversation = mark.getConversation();

var comment = conversation.addComment('This is the best comment ever.');

    creationTime :string

    Gets and sets the date and time when the comment was created.

    This is an ECMA 5 accessor property that is defined only in browsers supporting ECMA 5. This property is not available in the older browsers like IE8. For the greatest browser compatibility, use the corresponding getter and setter methods.

    Type:

    • string
    See:

    text :string

    Gets and sets the text content of the Comment.

    Methods

    getConversation() → {PCCViewer.Conversation}

    Gets the conversation that this comment is (or was) a part of.

    Returns:

    getData(key) → {string|object}

    Gets the data value for the given key, or gets a hash containing all key values, if a key was not provided.

    Note: If a hash is returned, this will be a new object each time it is called. Adding new properties to the returned hash will not add data to the Comment.

    Note: The returned data is not mutated or sanitized, which could lead to a security vulnerability if not sanitized properly before use.

    Parameters:

    Name Type Description
    key string

    The key for which to get the data value.

    See:

    Throws:

    If the key argument is null or otherwise not a string.

    Type
    Error

    Returns:

    • If a key argument was provided, it returns the associated value.
    • If a key argument was provided, but a value has not been associated with the key, then it returns undefined.
    • If a key was not provided, it returns a hash object containing all key-value pairs.
    Type
    string | object

    Example

    var comment = myConversation.addComment("Hello world.");

// The key "Author" is set the value "Mark".
comment.setData("Author", "Mark");

comment.setData("Severity", "Critical");

comment.getData("Author"); // returns "Mark"
comment.getData();         // returns {"Author":"Mark", "Severity":"Critical"}
comment.getData("FooBar"); // returns undefined

    getDataKeys() → {Array.<string>}

    Gets an array of data keys known to this Comment.

    See:

// Returns an empty array before key-value pairs are stored.
comment.getDataKeys(); // returns []

comment.getDataKeys(); // returns ["Author", "Severity"]

    getMarkupLayer() → {PCCViewer.MarkupLayer}

    getSessionData(key) → {string|object}

    Gets the session data value for the given key, or gets a hash containing all key values, if a key was not provided. Unlike PCCViewer.Comment#getData, this data is not saved with the annotation, it only lasts for the session.

    string | object

    Example

    var comment = myConversation.addComment("Hello world.");

// The key "Author" is set the value "Mark".
comment.setSessionData("Author", "Mark");

    See:

    Returns:

    Returns an array of data keys known to this Comment. If no data is stored, then an empty array will be returned.

comment.setCreationTime(janFirst1970);

    setData(key, value) → {PCCViewer.Comment}

    Sets the data value for the given key.

    • Overwrites any data value already associated with the given key.
    • There is no artificial limit imposed on the number of key-value pairs that are stored.
    • If limits on the number of key-value pairs are required, they should be enforced by calling code.
    • Setting the value as undefined results in no information for the key being persisted to the server.
    • The returned data is not mutated or sanitized, which could lead to a security vulnerability if not sanitized properly before use.

    Parameters:

    Name Type Description
    key string

    The key for which to set the data value.
