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
