Detailed Description

FNode Base class for node based evaluation within the Dataflow graph.

Note : Do NOT create mutable variables in the classes derived from FDataflowNode. The state is stored on the FContext. The Evaluate is const to allow support for multithreaded evaluation.

ForwardInput(...)

Forward an input to this output. This will not cache the value itself but cache a reference to the input connection cache entry. This is memory efficient and do not require a runtime copy of the data. Input and output references must match in type. Note that forwarding an input never sets a default value when no input is connected, use SafeForwardInput instead.

Parameters

Context	: The evaluation context that holds the data store.
InputReference	: Pointer to a input member of this node that needs to be forwarded.
Reference	: Pointer to a member of this node that corresponds with the output to set.

Freeze the node's outputs.

SafeForwardInput(...)

Forward an input to this output or set a default value if no input is connected. This is more memory efficient when an input is connected than setting the value. Input and output references must match in type.

Parameters

Context	: The evaluation context that holds the data store.
InputReference	: Pointer to a input member of this node that needs to be forwarded.
Reference	: Pointer to a member of this node that corresponds with the output to set.

This method extracts an element from the specified input at a specific index and set it as output to the specified output. When called, the input will be pulled as a result. If the input is not an array or if the index is out of bounds, a null value will be set on the output (which will result in a default value when read from)

inline

SetValue(...)

Set the value of the Reference output.

Note: If the compiler errors out with "You cannot bind an lvalue to an rvalue reference", then simply remove the explicit template parameter from the function call to allow for a const reference type to be deducted. const int32 Value = 0; SetValue<int32>(Context, Value, &Reference); // Error: You cannot bind an lvalue to an rvalue reference const int32 Value = 0; SetValue(Context, Value, &Reference); // Fine const int32 Value = 0; SetValue<const int32&>(Context, Value, &Reference); // Fine

Parameters

Context	: The evaluation context that holds the data store.
Value	: The value to store in the contexts data store.
Reference	: Pointer to a member of this node that corresponds with the output to set.
