Base class for actions on the revlib_parser.
The RevLib file parser revlib_parser(std::istream&, revlib_processor&, std::string*) gets an instance of a revlib_processor object as parameter.
For creating a circuit a circuit_processor already exists. Other processors can be implemented by inhereting from this class.
The base class provides virtual functions for each command in a RevLib file with corresponding parameters.
Only the methods which data is needed must be overriden.
revlib_processor | ( | ) |
Default constructor.
Initializes private data
|
virtual |
Default deconstructor.
Clears private data
|
protected |
Adds an annotation to the processor.
The parser adds all annotations in each step, i.e. every time it parses a line. Old annotations are removed before. The annotations can be read with current_annotation() when processing an action.
key | Key of the annotation |
value | Value of the annotation |
|
protected |
Clears the current annotations.
This method clears the current annotations, i.e. when a new line is processed by the parser.
|
protected |
Returns the current annotations.
|
protectedvirtual |
Called when parsing .begin command.
This method is called when a .begin command is parsed.
|
protectedvirtual |
Called when parsing comments.
This method is called when a comment (starting with a #) is parsed. The comment (text after the #) is stored in the parameter comment
.
comment | Comment (single line) |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing the .constants command.
This method is called when a .constants command is parsed. The constant in a std::vector can be accessed via their first
and last
iterator. A optional boolean value indicates whether the line is constant or not and in case it is constant, which constant line is represented.
first | Begin iterator of constants vector |
last | End iterator of constants vector |
Reimplemented in circuit_processor, and specification_processor.
|
protectedvirtual |
Called when parsing .end command.
This method is called when a .end command is parsed.
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .garbage command.
This method is called when a .garbage command is parsed. The garbage in a std::vector can be accessed via their first
and last
iterator. A boolean value indicates whether the line has a garbage output or not.
first | Begin iterator of garbage vector |
last | End iterator of garbage vector |
Reimplemented in circuit_processor, and specification_processor.
|
protectedvirtual |
Called when a gate is parsed.
This method is called when a gate is parsed providing the gate type in parameter target_type
and all connected line via their zero-index indices.
The last indices in the list line_indices
are the target lines. The number of target lines depends on the corresponding gate type.
target_type | Target type of the target line(s). |
line_indices | All connected lines, both control and target lines. |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .inputbus command.
This method is called when a .inputbus command is parsed. The first parameter name
is the name of the bus, whereas the corresponding variables can be accessed via the second parameter line_indices
, which already contains the indices rather than the variable names.
name | Name of the bus |
line_indices | Line indices of the variables of the bus |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .inputs command.
This method is called when a .inputs command is parsed. The inputs in a std::vector can be accessed via their first
and last
iterator.
first | Begin iterator of inputs vector |
last | End iterator of inputs vector |
Reimplemented in circuit_processor, and specification_processor.
|
protectedvirtual |
Called when parsing .module command.
This method is called when a .module command is parsed.
name | Name of the module (used later to add gates) |
filename | File-name of the module circuit |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .numvars command.
This method is called when a .numvars command is parsed. The number of variables is stored in the parameter numvars
.
numvars | Number of variables |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .outputbus command.
This method is called when a .outputbus command is parsed. The first parameter name
is the name of the bus, whereas the corresponding variables can be accessed via the second parameter line_indices
, which already contains the indices rather than the variable names.
name | Name of the bus |
line_indices | Line indices of the variables of the bus |
Reimplemented in circuit_processor.
|
protectedvirtual |
Called when parsing .outputs command.
This method is called when a .outputs command is parsed. The outputs in a std::vector can be accessed via their first
and last
iterator.
first | Begin iterator of outputs vector |
last | End iterator of outputs vector |
Reimplemented in circuit_processor, and specification_processor.
|
protectedvirtual |
Called when parsing .state command.
This method is called when a .state command is parsed. The first parameter name
is the name of the state (bus), whereas the corresponding variables can be accessed via the second parameter line_indices
, which already contains the indices rather than the variable names.
A .state command is modeled like a bus since it can contain more than one line index. Even if the state contains only one signal, this pattern is used.
name | Name of the state (bus) |
line_indices | Line indices of the variables of the state (bus) |
initial_value | Initial value for the state signal |
Reimplemented in circuit_processor.

protectedvirtual |
Called when a truth table line is parsed.
This method is called when a truth table line is parsed. A truth table line is parsed in a specification file.
The truth table line is given as first and last iterator over boost::optional<bool> values and as additional parameter the corresponding truth table line is given.
line_index | The corresponding truth table line |
first | Begin iterator over truth table output value |
last | End iterator over truth table output value |
Reimplemented in specification_processor.
|
protectedvirtual |
Called when parsing .variables command.
This method is called when a .variables command is parsed. The variables in a std::vector can be accessed via their first
and last
iterator.
first | Begin iterator of variables vector |
last | End iterator of variables vector |
|
protectedvirtual |

This method is called when a .version command is parsed. The version (as a std::string) is stored in the parameter version
.

A parser for the RevLib file format.
This function can read a circuit realization and truth table specifications in a format as proposed on RevLib. The function itself just realizes the parser and uses a revlib_processor instance which provides methods for implementation details.
For example, when reading the realization into a circuit structure, the read_realization_circuit_processor class can be used as instance.
in | Input stream containing the file |
reader | An instance of the revlib_processor |
base_directory | A base directory to look for included files. This is usually the directory of the loaded file-name. This member was introduced in RevKit version 1.1 |
error | A pointer to a string. In case the parsing fails, and error is not null, a error message is stored |
