public DataFlowNode(TInstruction? instruction)

Parameters

instruction TInstruction

The contents of the node.

Properties

InDegree

Gets a value indicating the number of incoming edges that this node is incident to.

public int InDegree { get; }

Property Value

int

Instruction

Gets the contents of the node.

public TInstruction? Instruction { get; set; }

Property Value

TInstruction

IsExternal

Gets a value indicating whether the data flow node represents an external data source.

public virtual bool IsExternal { get; }

Property Value

bool

Offset

Gets or sets the offset associated to the data flow node.

public long Offset { get; set; }

Property Value

long

OutDegree

VariableDependencies

Gets a collection of values that are assigned to variables that this node depends on.

public VariableDependencyCollection<TInstruction> VariableDependencies { get; }

Property Value

VariableDependencyCollection<TInstruction>

Methods

Disconnect()

Removes all incident edges (both incoming and outgoing edges) from the node, effectively isolating the node in the graph.

public void Disconnect()

GetDependants()

Obtains a collection of nodes that depend on this node.

public IEnumerable<DataFlowNode<TInstruction>> GetDependants()

Returns

IEnumerable<DataFlowNode<TInstruction>>

The dependant nodes.

GetIncomingEdges()

Obtains a collection of edges that refer to dependent nodes.

public IEnumerable<DataFlowEdge<TInstruction>> GetIncomingEdges()

Returns

IEnumerable<DataFlowEdge<TInstruction>>

The edges.

GetOutgoingEdges()

Obtains a collection of edges encoding all the dependencies that this node has.

public IEnumerable<DataFlowEdge<TInstruction>> GetOutgoingEdges()

Returns

IEnumerable<DataFlowEdge<TInstruction>>

The edges.

ToString()

public override string ToString()

Returns

string

UpdateOffset()

Synchronizes the node's offset with the offset of the embedded instruction.

public void UpdateOffset()
