Struct FunctionCall

go/engine/node/functioncall.go:30–36

FunctionCall invokes a compiled engine.Function. It evaluates input bindings in the surrounding scope, runs the function and applies output bindings back to the surrounding scope.

// to the surrounding scope.
type FunctionCall struct {
	engine.LinearNode
	fn              *engine.Function
	inputBindings   map[string]workflowapi.Expression    // arg uid → expression
	outputBindings  map[string]workflowapi.OutputBinding // return uid → binding
	toolDescription string
}

// NewFunctionCall builds a FunctionCall. Validates that every declared return
// has a matching output binding.
func NewFunctionCall(id string, fn *engine.Function, inputBindings map[string]workflowapi.Expression, outputBindings map[string]workflowapi.OutputBinding, toolDescription string) (*FunctionCall, error) {
