Symbol Table for Validation and other purposes. This symbol table is built from the AST model after syntactic parsing is complete. It will also work for any sub-tree of the model that is rooted by a ParentDefOf[Definition] node.
The symbol tree contains a mapping from leaf name to the entire list of parent definitions (symbols) as well as a mapping from definitions to their parents (parentage). Bot maps are built during a single pass of the AST.

THe name of the pass for inclusion in messages it produces.
THe name of the pass for inclusion in messages it produces. This must be implemented by the subclass

A signal that the processing is complete and no more calls to process will be made.
A signal that the processing is complete and no more calls to process will be made. This also gives the Pass subclass a chance to do post-processing as some computations can only be done after collecting data from the entire AST
Value parameters
- root
-
The root of the parsed model just as a convenience for post-processing
Attributes
- Definition Classes
- Source
- SymbolsPass.scala
The main implementation of the Pass.
The main implementation of the Pass. The AST is walked in a depth first manner calling this function for each definition it encounters.
Value parameters
- definition
-
The definition to be processed
- parents
-
The stack of definitions that are the parents of com.ossuminc.riddl.language.AST.Definition. This stack goes from immediate parent towards the root. The root is deepest in the stack.
Attributes

- SymbolsPass.scala
Generate the output of this Pass.
Generate the output of this Pass. This will only be called after all the calls to process have completed.
Value parameters
- root
-
The new com.ossuminc.riddl.language.AST.Root of the model that the pass computed
Attributes
- Returns
-
an instance of the output type
- Definition Classes

Inherited methods
Pre-process the root before actually traversing.
Pre-process the root before actually traversing. This is also a signal that the processing is about to start.
Value parameters
- root
-
A com.ossuminc.riddl.language.AST.Root node which encapsulates the whole model. This is the state of the Root as of the last pass.
Attributes
- Returns
-
Typically returns the same Root objects with changes in subsequent levels, but it entirely possibly to completely reorganize the hierarchy, including its root node.
