Method Detail

setStructureWalker

public void setStructureWalker(@Nonnull
                               StructureWalker<O> walker)

Parameters:

walker - the structure walker to use with this object walker

walkStructure

public void walkStructure(@Nonnull
                          OWLObjectVisitorEx<?> v)

Parameters:

v - visitor to use over the objects

walkStructure

public void walkStructure(@Nonnull
                          OWLObjectVisitor v)

Parameters:

v - visitor to use over the objects

getOntology

@Nullable
public OWLOntology getOntology()

Gets the last ontology to be visited.

Returns:

The last ontology to be visited

getAxiom

public OWLAxiom getAxiom()

Gets the last axiom to be visited.

Returns:

The last axiom to be visited, or null if an axiom has not be visited

getAnnotation

public OWLAnnotation getAnnotation()

Gets the last annotation to be visited.

Returns:

The last annotation to be visited (may be null)

getClassExpressionPath

@Nonnull
public List<OWLClassExpression> getClassExpressionPath()

Gets the current class expression path. The current class expression path is a list of class expressions that represents the containing expressions for the current class expressions. The first item in the path (list) is the root class expression that was visited. For i between 0 and pathLength, the item at index i+1 is a direct sub-expression of the item at index i. The last item in the path is the current class expression being visited.

Returns:

A list of class expressions that represents the path of class expressions, with the root of the class expression being the first element in the list.

isFirstClassExpressionInPath

public boolean isFirstClassExpressionInPath(@Nonnull
                                            OWLClassExpression classExpression)

Determines if a particular class expression is the first (or root) class expression in the current class expression path.

Parameters:

classExpression - The class expression

Returns:

true if the specified class expression is the first class expression in the current class expression path, otherwise false (false if the path is empty)

getDataRangePath

@Nonnull
public List<OWLDataRange> getDataRangePath()

Gets the current data range path. The current data range path is a list of data ranges that represents the containing expressions for the current data ranges. The first item in the path (list) is the root data range that was visited. For i between 0 and pathLength, the item at index i+1 is a direct sub-expression of the item at index i. The last item in the path is the current data range being visited.

Returns:

A list of data ranges that represents the path of data ranges, with the root of the data range being the first element in the list.

setAxiom

public void setAxiom(OWLAxiom axiom)

Allow the structure walker to set the current axiom

Parameters:

axiom - the axiom to set

setAnnotation

public void setAnnotation(OWLAnnotation node)

Allow the structure walker to set the current annotation

Parameters:

node - the annotation to set
