Package Dependencies
AFC’s build enforces package dependency rules over and above the ones governed by the public keyword. This is done using the definitions src/scripts/components.yaml, a YAML file. From it, we produce checking rules for Macker and this
What follows is a subsystem and package breakdown generated from components.yaml.
Core
AFC’s functional model to byte code compiler and runtime. The spreadsheet compiler sits on top of this and first transforms a spreadsheet into a functional model.
Runtime (formulacompiler-runtime)
All the components needed to run compiled engines.
Api.event
org.formulacompiler.runtime.event
Api.spreadsheet
org.formulacompiler.runtime.spreadsheet
API
org.formulacompiler.runtime
Core
org.formulacompiler.runtime.internal
Spreadsheet
org.formulacompiler.runtime.internal.spreadsheet
JVM
org.formulacompiler.runtime.internal.bytecode
Compiler (formulacompiler-compiler)
Functional model to byte code compiler. Does not have a fully sufficient public API yet. In particular, the functional model itself is not yet exposed.
API
org.formulacompiler.compiler
Logging
org.formulacompiler.compiler.internal.logging
Core
org.formulacompiler.compiler.internal
Expressions
org.formulacompiler.compiler.internal.expressions
Expressions.parser
org.formulacompiler.compiler.internal.expressions.parser
Templates
Template native Java implementations of low-level functions. Used directly by the generated expression interpreters and as templates for the generated bytecode compilers.
org.formulacompiler.compiler.internal.templates
Model
org.formulacompiler.compiler.internal.model
Compiler
Abstract two-stage compiler – delegates both an initial model transform and then transformed model to bytecode compilation.
org.formulacompiler.compiler.internal.engine
Interpreter
Interprets expressions at compile-time to do constant-folding.
org.formulacompiler.compiler.internal.model.interpreter
Analysis
Performs data type analysis.
org.formulacompiler.compiler.internal.model.analysis
Rewriting
Rewrites higher-level expressions in terms of lower-level constructs.
org.formulacompiler.compiler.internal.model.rewriting
Optimizer
Performs constant-folding.
org.formulacompiler.compiler.internal.model.optimizer org.formulacompiler.compiler.internal.model.optimizer.consteval
Transformer
Implements the first stage of the abstract two-stage compiler.
org.formulacompiler.compiler.internal.model.transformer
JVM
Compiles a transformed model to byte code.
org.formulacompiler.compiler.internal.bytecode
Decompiler (formulacompiler-decompiler)
Byte code engine decompiler.
API
org.formulacompiler.decompiler
JVM
org.formulacompiler.decompiler.internal.bytecode
Spreadsheet
AFC’s spreadsheet to functional model and – in the end – bytecode engine compiler.
Compiler (formulacompiler-spreadsheet)
The core compiler which does everything except load and save spreadsheets in the different supported file formats.
API
org.formulacompiler.spreadsheet
Model
Implements the abstract internal model of a spreadsheet.
org.formulacompiler.spreadsheet.internal
Binding
Defines a binding of spreadsheet model elements to the user’s own Java classes.
org.formulacompiler.spreadsheet.internal.binding
Binder
Used to create a spreadsheet binding.
org.formulacompiler.spreadsheet.internal.binder
Builder
Used to create internal spreadsheet models from scratch.
org.formulacompiler.spreadsheet.internal.builder
Compiler
Compiles a spreadsheet model to a bytecode engine by way of first compiling to a functional model and then using AFC’s functional model compiler on that.
org.formulacompiler.spreadsheet.internal.compiler
Util
Convenience classes implementing simplified API for AFC.
org.formulacompiler.spreadsheet.internal.util
Parser
Base for the spreadsheet function parsers following Excel and OpenFormula specification.
org.formulacompiler.spreadsheet.internal.parser
Load
Spreadsheet loader implementation that dispatches to actual specific loader implementations by file extension.
org.formulacompiler.spreadsheet.internal.loader
Save
Spreadsheet saver implementation that dispatches to actual specific saver implementations by file extension.
org.formulacompiler.spreadsheet.internal.saver
Excel.xls (formulacompiler-spreadsheet-excel-xls)
Excel .xls file format handlers.
Load
org.formulacompiler.spreadsheet.internal.loader.excel.xls
Save
org.formulacompiler.spreadsheet.internal.saver.excel.xls
Openoffice.ods (formulacompiler-spreadsheet-opendocument)
OpenOffice .ods (OpenDocument) file format handlers.
Load
