MessageFindingVisitor class

This visits the program source nodes looking for Intl.message uses that conform to its pattern and then creating the corresponding IntlMessage objects. We have to find both the enclosing function, and the Intl.message invocation.

Constructors

MessageFindingVisitor(MessageExtraction extraction)

Properties

extraction → MessageExtraction
The message extraction in which we are running.
final
generateNameAndArgs ↔ bool
Should we generate the name and arguments from the function definition, meaning we're running in the transformer.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
messages → Map<String, MainMessage>
Accumulates the messages we have found, keyed by name.
final
name ↔ String
getter/setter pair
parameters ↔ FormalParameterList?
We keep track of the data from the last MethodDeclaration, FunctionDeclaration or FunctionExpression that we saw on the way down, as that will be the nearest parent of the Intl.message invocation.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

addIntlMessage(MethodInvocation node) → bool
Check that the node looks like an Intl.message invocation, and create the IntlMessage object from it and store it in messages. Return true if we successfully extracted a message and should stop looking. Return false if we didn't, so should continue recursing.
checkValidity(MethodInvocation node) → String?
Returns a String describing why the node is invalid, or null if no reason is found, so it's presumed valid.
looksLikeIntlMessage(MethodInvocation node) → bool
Return true if node matches the pattern we expect for Intl.message()
messageFromDirectPluralOrGenderCall(MethodInvocation node) → MainMessage?
Create a MainMessage from node using the name and parameters of the last function/method declaration we encountered and the parameters to the Intl.plural or Intl.gender call.
messageFromIntlMessageCall(MethodInvocation node) → MainMessage?
Create a MainMessage from node using the name and parameters of the last function/method declaration we encountered and the parameters to the Intl.message call.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

visitMethodInvocation(MethodInvocation node) → void
