Method Detail

isConstraining

boolean isConstraining()

Returns the type of this attribute.

Returns:

true (constraining) / false (inferring)

setConstraining

void setConstraining(boolean constraining)

Sets the type of this attribute.

Parameters:

constraining - true (constraining) / false (inferring)

getMinCardinality

int getMinCardinality()

Returns the minimal cardinality constraint of this attribute. The cardinality option is only available to Concept Attributes.

Returns:

number indicating the minimal cardinality constraint

setMinCardinality

void setMinCardinality(int min)

Sets the minimal cardinality constraint of this attribute. The cardinality option is only available to Concept Attributes.

Parameters:

min - number indicating the minimal cardinality constraint

getMaxCardinality

int getMaxCardinality()

Returns the maximal cardinality constraint of this attribute. The cardinality option is only available to Concept Attributes.

Returns:

number indicating the maximal cardinality constraint

setMaxCardinality

void setMaxCardinality(int max)

Sets the maximal cardinality constraint of this attribute. The cardinality option is only available to Concept Attributes.

getConcept

Concept getConcept()

Returns the Concept described by this attribute.

Returns:

Concept

listTypes

java.util.Set listTypes()

Returns the list of allowed Type for the current attribute.

Returns:

Set of Type objects

addType

void addType(Type type)
             throws InvalidModelException

Adds a new Type as range for this attribute.

Parameters:

type - the Type to be added

Throws:

InvalidModelException

removeType

void removeType(Type type)
                throws InvalidModelException

Removes a Type for this attribute.

Parameters:

type - the Type to be removed

Throws:

InvalidModelException

isReflexive

boolean isReflexive()

Returns if this attribute is defined as reflexive. This option is available only for the concept attribtues.

Returns:

setReflexive

void setReflexive(boolean reflexive)

Sets this attribute whether to be reflexive. This option is available only for the concept attribtues.

Parameters:

reflexive - is reflexive

isSymmetric

boolean isSymmetric()

Returns if this attribute is defined as symmetric. When an attribute is specified as being symmetric, this means that if an individual a has a symmetric attribute att with value b, then b also has attribute att with value a. This option is available only for the concept attribtues.

Returns:

setSymmetric

void setSymmetric(boolean symmetric)

Sets this attribute whether to be symmetric. This option is available only for the concept attribtues.

Parameters:

symmetric - is reflexive

isTransitive

boolean isTransitive()

Returns if this attribute is defined as transitive. When an attribute is specified as being transitive, this means that if three individuals a, b and c are related via a transitive attribute att in such a way: a att b att c then c is also a value for the attribute att at a: a att c. This option is available only for the concept attribtues.

Returns:

setTransitive

void setTransitive(boolean trans)

Sets this attribute whether to be transitive. This option is available only for the concept attribtues.

Parameters:

trans - is reflexive

getInverseOf

Attribute getInverseOf()

Returns the inverse attribute of this attribute. When an attribute is specified as being the inverse of another attribute, this means that if an individual a has an attribute att1 with value b and att1 is the inverse of a certain attribute att2, then it is inferred that b has an attribute att2 with value a. This option is available only for the concept attribtues.

Returns:

null or the inverse attribute

setInverseOf

void setInverseOf(Attribute attr)

Sets this attribute to be inverse of another attribute.

Parameters:

attr - attribute to be set as inverse of or null to remove the current inverse attribute
