Method Detail

getProof

public Proof getProof()

Description copied from interface: Proof.State

Get the enclosing proof for this step. Every step must be associated with a proof, and all connected steps must be in the same proof.

Specified by:

getProof in interface Proof.State

Returns:

getParent

public T getParent()

Description copied from interface: Proof.State

Get the parent (i.e. before) state for this step. This is null if this state represents the root of the proof.

Specified by:

getParent in interface Proof.State

Returns:

getRule

public Proof.Rule getRule()

Description copied from interface: Proof.State

Get the name of the rule used for this step.

Specified by:

getRule in interface Proof.State

Returns:

getDependencies

public List<Formula> getDependencies()

Description copied from interface: Proof.State

Get the formulae on which this step depends

Specified by:

getDependencies in interface Proof.State

Returns:

numberOfChildren

public int numberOfChildren()

Description copied from interface: Proof.State

Get the number of child steps originating from this step

Specified by:

numberOfChildren in interface Proof.State

Returns:

getChild

public T getChild(int ith)

Description copied from interface: Proof.State

Get the child state resulting from this step

Specified by:

getChild in interface Proof.State

Returns:

applyBypass

public void applyBypass(Proof.State child)

Specified by:

applyBypass in interface Proof.State
