                             String rawValue,
                             ControllerServiceLookup serviceLookup,

StandardPropertyValue

public StandardPropertyValue(ResourceContext resourceContext,
                             String rawValue,
                             ControllerServiceLookup serviceLookup,
                             ParameterLookup parameterLookup,
                             PreparedQuery preparedQuery,
                             VariableRegistry variableRegistry)

Constructs a new StandardPropertyValue with the given value & service lookup and indicates whether or not the rawValue contains any NiFi Expressions. If it is unknown whether or not the value contains any NiFi Expressions, the StandardPropertyValue(ResourceContext, String, ControllerServiceLookup, ParameterLookup, VariableRegistry) constructor should be used or true should be passed. However, if it is known that the value contains no NiFi Expression, that information should be provided so that calls to evaluateAttributeExpressions() are much more efficient

Parameters:

resourceContext - the context in which resources are to be understood

rawValue - value

serviceLookup - lookup

parameterLookup - the parameter lookup

preparedQuery - query

variableRegistry - variableRegistry
