Method Detail

setHasValue

public void setHasValue(RDFNode value)

Assert that this restriction restricts the property to have the given value. Any existing statements for hasValue will be removed.

Parameters:

value - The RDF value (an individual or a literal) that is the value that the restricted property must have to be a member of the class defined by this restriction.

Throws:

OntProfileException - If the Profile.HAS_VALUE() property is not supported in the current language profile.

getHasValue

public RDFNode getHasValue()

Answer the RDF value that all values of the restricted property must be equal to.

Returns:

An RDFNode that is the value of the restricted property

Throws:

OntProfileException - If the Profile.HAS_VALUE() property is not supported in the current language profile.

hasValue

public boolean hasValue(RDFNode value)

Answer true if this property restriction has the given RDF value as the value which all values of the restricted property must equal.

Parameters:

value - An RDF value to test

Returns:

True if the given value is the value of the restricted property in this restriction

Throws:

OntProfileException - If the Profile.HAS_VALUE() property is not supported in the current language profile.

removeHasValue

public void removeHasValue(RDFNode value)

Remove the statement that this restriction requires the restricted property to have the given value. If this statement is not true of the current model, nothing happens.

Parameters:

value - An RDF value that is to be removed as the required value for the restricted property
