public class AST0 extends AbstractAST implements java.util.List<IExpr>, java.lang.Cloneable, java.io.Externalizable, java.util.RandomAccess
Immutable (A)bstract (S)yntax (T)ree of a given function with no argument.
In Symja, an abstract syntax tree (AST), is a tree representation of the
abstract syntactic structure of the Symja source code. Each node of the tree
denotes a construct occurring in the source code. The syntax is 'abstract' in
the sense that it does not represent every detail that appears in the real
syntax. For instance, grouping parentheses are implicit in the tree
structure, and a syntactic construct such as a Sin[x] expression
will be denoted by an AST with 2 nodes. One node for the header
Sin and one node for the argument x.
