Constructor Detail

Proposition

public Proposition(Argument[] arguments)
            throws ArgumentException
Constructs a mathematical proposition with its proof.

Parameters:
arguments - sentence and its proof
Throws:
ArgumentException - if there is not exactly two arguments or the first argument is not an instance of Sentence or the second argument is no instance of ProofLineList.
Method Detail

check

public final void check(Module module,
                        String label)
                 throws ArgumentException
Check if proof is correct.

Specified by:
check in interface ParagraphCheck
Parameters:
module - module
label - label of paragraph
Throws:
ArgumentException - if proof is not correct

compress

public final void compress()
                    throws ArgumentException
Remove all double and unused proof lines.

Throws:
ArgumentException - if proof is there were any illegal line references
IllegalArgumentException - if there was a programming error

reduceRuleVersion

public final void reduceRuleVersion(Module module,
                                    Version version)
                             throws ArgumentException
Reduce needed rule version and change proof lines in that way.

Parameters:
module - this is the connected module
Throws:
ArgumentException - if a proof line has major errors in their line references
UnsupportedOperationException - if there is a rule which couldn't yet be reduced to simper rules because the reduction for that rule isn't implemented
IllegalArgumentException - if there was a programming error

replaceProofLineByProofLines

public final void replaceProofLineByProofLines(ProofLineList proofLines,
                                               int position)
Replace a single proof line by some (other) proof lines. If the replacement lines are empty, nothing is done; by calling compress the caller could remove the proof line.

Parameters:
proofLines - these proof lines should be inserted, the line references must be already correct
position - this line should be replaced by the new proof lines
Throws:
IllegalArgumentException - if position is not a valid one, or the remaping failed because the given proof lines had illegal references

create

public final Argument create(Argument[] arguments)
                      throws ArgumentException
Description copied from interface: Argument
Create a new Argument with given arguments.

Specified by:
create in interface Argument
Specified by:
create in class AbstractDynamicArgumentList
Throws:
ArgumentException

toString

public final String toString()
Description copied from interface: Argument
Get the argument in String form.

Specified by:
toString in interface Argument
Specified by:
toString in class AbstractDynamicArgumentList
