Flowchart family

AnnotationNode (class)

Annotation node: dashed border rectangle for adding notes and comments to flowcharts. Can optionally attach to another node via a dotted connector line.

CardNode (class)

Card node: rectangle with cut corner for punch card or card-based storage. Legacy flowchart symbol for card-based data processing.

CodeLanguage (enum)

Target languages for FlowchartCodeGenerator.

CollateNode (class)

Collate node: inverted trapezoid for sorting or collating data. Used to represent organizing or ordering operations.

CommentNode (class)

Comment node: fold-over corner rectangle for additional notes or comments. Similar to AnnotationNode but with a distinctive folded corner appearance.

ConnectorDirection (enum)

ConnectorNode (class)

Off-page connector: pentagon shape for referencing flow on another page/diagram. Use matching ConnectorId to link From/To pairs.

DataNode (class)

Data (Database) node: cylinder shape representing a data store.

DecisionNode (class)

Decision node: diamond shape with Yes/No ports (left/right) plus optional top/bottom ports.

DelayNode (class)

Delay node: half-circle or rounded shape indicating a pause/wait in the process.

DirectAccessNode (class)

Direct Access Storage node: cylinder with flat bottom for random access storage (hard disk).

DisplayNode (class)

Display node: rounded rectangle with curved bottom (like a monitor) for output display.

DocumentNode (class)

Document: rectangle with a curved bottom edge and centered label.

DoWhileLoopNode (class)

Do-While loop node: executes body at least once, then checks condition at end. Similar to WhileLoop but with condition checked after execution.

ExtractNode (class)

Extract node: right-pointing triangle for data extraction operations. Used for selecting, filtering, or extracting specific data from a dataset.

FlowchartCodeGenerator (class)

Generates structured code from a flowchart diagram. Conventions: for decision nodes the first output port is the true branch and the second is the false branch; for loop nodes the first output port is the loop body and the second is the exit.

FlowchartControl (class)

Base class for Flowchart nodes providing consistent sizing and port layout helpers.

FlowchartSimulator (class)

Step-through execution of a flowchart. The simulator walks connection lines in port order; when a node has multiple outgoing edges (decisions, loops, forks) the optional BranchSelector chooses the branch (defaults to the first edge).

ForkNode (class)

Fork node (parallel split): thick vertical bar with single input and multiple parallel outputs. Represents splitting flow into concurrent/parallel paths.

ForLoopNode (class)

For loop node: rectangle with loop icon and condition text. Represents iterative processing with init, condition, and increment.

InputOutputNode (class)

Input/Output (parallelogram) node with slanted sides and centered label.

InternalStorageNode (class)

Internal Storage node: rectangle with vertical lines for internal memory/storage. Used for data structures in memory (arrays, buffers, caches).

JoinNode (class)

Join node (parallel synchronization): thick vertical bar with multiple inputs and single output. Represents waiting for all parallel paths to complete before continuing.

LoopLimitNode (class)

Loop Limit node: hexagon with horizontal orientation for loop boundaries. Used to mark the beginning or end of a loop structure.

LoopLimitType (enum)

ManualInputNode (class)

Manual Input node: parallelogram with top slanted (wider at top) for manual data entry.

ManualOperationNode (class)

Manual operation node: trapezoid shape (top wider than bottom) for human-performed tasks.

MergeNode (class)

Merge node: inverted triangle for combining multiple flow paths (no synchronization logic).

MultiDocumentNode (class)

Multi-Document node: stacked documents for multiple document output. Visual: Multiple overlapping document shapes with curved bottoms.

OffPageReferenceNode (class)

Off-Page Reference node: upside-down house shape (pentagon) for page references. Alternative to ConnectorNode with a different visual style.

OrNode (class)

Or node: logic gate shape for conditional OR operations. Circle with OR symbol. Used when any input condition can proceed to the next step.

PredefinedProcessNode (class)

Predefined Process: rectangle with vertical double-struck edges and centered label.

PreparationNode (class)

Preparation node: horizontal hexagon for initialization/setup steps. Commonly used for variable declarations, configuration, or setup tasks.

ProcessNode (class)

Process node: rectangle with optional rounded corners and centered label.

SequentialAccessNode (class)

Sequential Access Storage node: elongated oval for sequential access storage devices. Used for devices like magnetic tape where data must be accessed sequentially.

SimulationEdge (class)

A candidate transition from the current simulation node.

SimulationStepEventArgs (class)

Event args raised after each simulation step.

SortNode (class)

Sort node: two overlapping triangles for sorting operations.

StartEndNode (class)

Start/End node (terminator): pill-shaped rounded rectangle with a label.

StoredDataNode (class)

Stored data node: parallelogram tilted to the right for data storage (tape, disk). Different from InputOutput which tilts both sides.

SubProcessNode (class)

Sub-process node: rectangle with double border for calling/referencing another process. Can be collapsed (shows + icon) or expanded to show nested details.

SummingJunctionNode (class)

Summing Junction node: X in a circle for combining/merging multiple inputs. Different from OR gate - represents mathematical summation or aggregation.

TapeNode (class)

Tape node: rounded bottom semicircle shape for magnetic tape storage. Legacy flowchart symbol for sequential tape-based storage.

WhileLoopNode (class)

While loop node: hexagon (vertical orientation) with condition text. Represents loop that executes while condition is true.
