Constructor Detail

OWLUntypedConstantImpl

public OWLUntypedConstantImpl(OWLDataFactory dataFactory,
                              java.lang.String literal,
                              java.lang.String lang)

Method Detail

getLang

public java.lang.String getLang()

Description copied from interface: OWLUntypedConstant

Gets the language tag (if present)

Specified by:

getLang in interface OWLUntypedConstant

Returns:

A String which represents the langauge tag, or null if there is no language tag

hasLang

public boolean hasLang()

Description copied from interface: OWLUntypedConstant

Language tags on untyped constants are optional. This method determines if the language tag is present.

Specified by:

hasLang in interface OWLUntypedConstant

Returns:

true if there is a language tag, or false if there is not a langauge tag.

hasLang

public boolean hasLang(java.lang.String lang)

Description copied from interface: OWLUntypedConstant

Determines if this constant has a specific language tag.

Specified by:

hasLang in interface OWLUntypedConstant

Parameters:

lang - The specific lang to test for.

Returns:

true if this constant has the specified langauge tag, or false if this constant does not have a language tag or if this constant has a language tag that is not equal to the specified language tag.

isTyped

public boolean isTyped()

Description copied from interface: OWLConstant

Determines if this constant is typed (i.e. an instance of OWLTypedConstant)

Specified by:

isTyped in interface OWLConstant

Returns:

true if the constant is typed, or false if the constant is untyped.

asOWLTypedConstant

public OWLTypedConstant asOWLTypedConstant()

Description copied from interface: OWLConstant

If this constant is a typed constant (i.e. if the isTyped method returns true then this method obtains this constant as a typed constant. If isTyped returns false because this constant is not a typed constant then calling this method will cause an OWLRuntimeException to be thrown.

Specified by:

asOWLTypedConstant in interface OWLConstant

asOWLUntypedConstant

public OWLUntypedConstant asOWLUntypedConstant()

Description copied from interface: OWLConstant

If this constant is an untyped constant (i.e. if the isTyped method returns false then this method obtains this constant as an untyped constant. If the isTyped method returns true because this method is a typed constant, then calling this method will cause an OWLRuntimeException to be thrown.

Specified by:

asOWLUntypedConstant in interface OWLConstant

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class OWLConstantImpl

accept

public void accept(OWLDataVisitor visitor)

Specified by:

accept in interface OWLConstant

accept

public void accept(OWLObjectVisitor visitor)

Specified by:

accept in interface OWLObject

accept

public <O> O accept(OWLDataVisitorEx<O> visitor)

Specified by:

accept in interface OWLConstant

accept

public <O> O accept(OWLObjectVisitorEx<O> visitor)

Specified by:
