Package edu.udel.cis.vsl.abc.ast.IF

package edu.udel.cis.vsl.abc.ast.IF

Module ast defines an Abstract Syntax Tree representation of a program, the AST. This module is large and is therefore divided into several submodules. Each submodule has its own interface. This package proper contains the module entry point, ASTs and an exception class specific to ASTs.

This module is decomposed into the following submodules:

• main: this package, declaring the interfaces AST and ASTFactory.
• ast.value
  • responsibilities: representation of concrete value, such as characters, integers, floating point values
  • interface: edu.udel.cis.vsl.abc.ast.value.IF
  • entry point: Values
• ast.type
  • responsibilities: representation of types
  • interface: edu.udel.cis.vsl.abc.ast.type.IF
  • entry point: Types
• ast.entity
  • responsibilities: representation of abstract program entities which can be named by an identifier, including variables, functions, labels, scopes, structures, unions, enumerations, enumerators, and typedefs
  • interface: edu.udel.cis.vsl.abc.ast.entity.IF
  • entry point: Entities
• ast.conversion
  • responsibilities: representation of C's implicit conversions, such as the conversion of an array to a pointer to the first element of the array, and so on
  • interface: edu.udel.cis.vsl.abc.ast.conversion.IF
  • entry point: Conversions
• ast.node
  • responsibilities: representation of AST nodes
  • interface: edu.udel.cis.vsl.abc.ast.node.IF
  • entry point: Nodes

Class	Description
AST	A representation of a program as an abstract syntax tree.
ASTException	Runtime exception thrown when something goes wrong with the AST.
ASTFactory	An ASTFactory is used to create all objects associated to an AST.
ASTs	Factory class providing static method to produce a new ASTFactory.
DifferenceObject
DifferenceObject.DiffKind
StandardTypes	The class collects together the standard type definitions, e.g., size_t, ptrdiff_t, etc.
