Common data structures are automatically identified and displayed structurally. The result is animated when changes occur, as when a node is added to a linked list. Structural views of linked data structures display local variable nodes and their relation to the main structure. Structural views show the internal structure of trees, linked lists, hash tables, etc. For example, a content-based view shows ArrayList and LinkedList in an identical way, as a list of elements. The Java object viewers in jGRASP provide interface-based, structural, and other views of data structures and other objects and primitives during debugging and workbench operations. The editing window provides CSD-based folding and a 'context hint' feature that displays the first line of a code structure that is off-screen when the mouse is hovered over its CSD structure.

jGRASP produces CSDs for Java, C, C++, Objective-C, Ada, and VHDL. Its purpose is to improve the readability of source code. The Control Structure Diagram (CSD) is a control flow diagram that fits into the space normally taken by indentation in source code. It can be configured to work with most free and commercial compilers for any programming language. The jGRASP web site offers downloads for Windows, Mac OS, and as a generic ZIP file suitable for Linux and other systems.įor languages other than Java, jGRASP is a source code editor. GRASP (Linux, UNIX) and pcGRASP (Windows) are written in C/C++, whereas jGRASP is written in Java (the 'j' in jGRASP means it runs on the JVM). JGRASP is implemented in Java, and runs on all platforms with a Java Virtual Machine (Java version 1.8 or higher). The runtime data structure visualizations are also available as plugins for IntelliJ IDEA, Android Studio, and Eclipse.

It produces static visualizations of source code structure and visualizations of data structures at runtime. JGRASP is a development environment that includes the automatic creation of software visualizations.
