Techniques for navigating interactive diagrams are provided. In one technique, a first content of an interactive diagram is presented in a content display area of a user interface. The interactive diagram also includes second content that is outside the content display area of the user interface. A boundary is identified that encapsulates the first content and the second content. While displaying a scrolling control on the user interface, first user input is received that causes a portion of the second content to be presented in the content display area and a portion of the first content to no longer be presented in the content display area. In response receiving second user input to view a portion of the interactive diagram that is outside the boundary, a visual appearance of one or more elements of the scrolling control is updated.

Diagram navigation

Techniques for encoding node locations are provided. In some examples, a node in a hierarchy such as a document object model (DOM) may be expressed as a location path from the root node of the hierarchy to the node. Each node on the location path may be encoded using a mapping between the type and/or index of the node and a set of characters such as ASCII characters. The encoding of each node on the path be concatenated to form the encoded location path. The encoding seeks to minimize the length of the encoded location path. For example, in an embodiment, a single ASCII character may be used to encode both the type and the index of a node. In an embodiment, breakpoint locations may be encoded using methods provided to reduce storage and computing resource required.

Compact encoding of node locations

Known techniques for generating serial information to represent program objects (serialization) and to recreate program objects from the serial information (deserialization) often impose limitations on the changes that may be made to the class structure or definition of the program object. Many changes to the class structure introduce incompatibilities that prevent a one version of a program object from being recovered from serial information that represent a different version of the program object. Techniques are disclosed that overcome this difficulty by allowing the serialization and deserialization processes to be adaptive according to the version of the program object.
