Constructor Detail

FlowExpressionContext

public FlowExpressionContext(FlowExpressions.Receiver receiver,
                             List<FlowExpressions.Receiver> arguments,
                             BaseContext checkerContext)

Creates context for parsing a flow expression.

Parameters:

receiver - used to replace "this" in a flow expression and used to resolve identifiers in the flow expression with an implicit "this"

arguments - used to replace parameter references, e.g. #1, in flow expressions, null if no arguments

checkerContext - used to create FlowExpressions.Receivers
