Make new factory. Per default (Ref)CommonAST instances are generated. AST Support code shared by TreeParser and Parser. We use delegation to share code (and have only one bit of code to maintain) rather than subclassing or superclassing (forces AST support code to be loaded even when you don't want to do AST stuff). This class collects all factories of AST types used inside the code. New AST node types are registered with the registerFactory method. On creation of an ASTFactory object a default AST node factory may be specified. When registering types gaps between different types are filled with entries for the default factory. |
|
Initialize factory with a non default node type. factory_node_name should be the name of the AST node type the factory generates. (should exist during the existance of this ASTFactory instance) |
|
Destroy factory.
|
|
Add a child to the current AST. Add a child to the current AST |
|
|
|
Create new AST node and initialize contents from a stream.
|
|
Create new AST node and initialize contents from a token.
|
|
Create duplicate of tr. Create a new empty AST node; if the user did not specify an AST node type, then create a default one: CommonAST. |
|
Create AST node of the right type for 'type' and initialize with txt.
|
|
Create AST node of the right type for 'type'.
|
|
Create new empty AST node. The right default type shou. Create a new empty AST node; if the user did not specify an AST node type, then create a default one: CommonAST. |
|
Deep copy a single node. This function the new clone() methods in the AST interface. Returns a new RefAST(nullASTptr) if t is null. |
|
Duplicate tree including siblings of root. Duplicate tree including siblings of root. |
|
Duplicate a tree, assuming this is a root node of a tree-- duplicate that node and what's below; ignore siblings of root node. |
|
|
|
get the name of the node 'type'

|
|
Make a tree from a list of nodes, where the nodes are contained in an ASTArray object. The ASTArray is deleted after use. |
|
Make a tree from a list of nodes. The first element in the array is the root. If the root is null, then the tree is a simple list not a tree. Handles null children nodes correctly. For example, make(a, b, null, c) yields tree (a b c). make(null,a,b) yields tree (nil a b). |
|
Make an AST the root of current AST.
|
|
Register a node factory for the node type type with name ast_name.
|
|
Set a new default AST type. factory_node_name should be the name of the AST node type the factory generates. (should exist during the existance of this ASTFactory instance). Only change factory between parser runs. You might get unexpected results otherwise. |
|
Set the maximum node (AST) type this factory may encounter.
