| LiteralLabel | | final public class LiteralLabel (Code) | | Represents the "contents" of a Node_Literal.
These contents comprise a lexical form, an optional language tag,
and optional datatype structure and a value.

| Constructor Summary | |
| public | LiteralLabel(String lex, String lang)
Build a plain literal label from its lexical form. | | public | LiteralLabel(Object value, String lang, RDFDatatype dtype)
Build a typed literal label from its value form. | | public | LiteralLabel(String lex, Object value, String lang, RDFDatatype dtype)
Build a typed literal label supplying both value and lexical form.
The caller guarantees that the lexical form is legal,
and the value corresponds. | | public | LiteralLabel(Object value)
Build a typed literal label from its value form using
whatever datatype is currently registered as the the default
representation for this java class. | | public | LiteralLabel(String s, String lg, boolean xml)
Old style constructor. |
| Method Summary | |
| public static LiteralLabel | createLiteralLabel(String lex, String lang, RDFDatatype dtype)
| | public boolean | equals(Object other)
Answer true iff this literal is syntactically equal to other. | | public RDFDatatype | getDatatype()
Answer the datatype of this literal, null if it is untyped. | | public String | getDatatypeURI()
Answer the datatype URI of this literal, null if it untyped. | | public int | getDefaultHashcode()
Answer the default hash value, suitable for datatypes which have values
which support hashCode() naturally: it is derived from its value if it is
well-formed and otherwise from its lexical form. | | public Object | getIndexingValue()
| | public String | getLexicalForm()
Answer the lexical form of this literal, constructing it on-the-fly
(and remembering it) if necessary. | | public Object | getValue()
Answer a suitable instance of a Java class representing this literal's
value. | | public int | hashCode()
Answer the hashcode of this literal, derived from its value if it's
well-formed and otherwise its lexical form. | | public boolean | isWellFormed()
Answer truee iff this is a well-formed literal. | | public boolean | isXML()
Answer true iff this is a well-formed XML literal. | | public String | language()
Answer the language associated with this literal (the empty string if
there's no language). | | protected void | normalize()
Normalize the literal. | | public boolean | sameValueAs(LiteralLabel other)
Answer true iff this literal represents the same (abstract) value as
the other one. | | public String | toString(boolean quoting)
Answer a human-acceptable representation of this literal value.
This is NOT intended for a machine-processed result. | | public String | toString()
|
| LiteralLabel | | public LiteralLabel(String lex, String lang)(Code) | | Build a plain literal label from its lexical form.
Parameters:
lex - the lexical form of the literal
Parameters:
lang - the optional language tag, only relevant for plain literals |
| LiteralLabel | | public LiteralLabel(Object value, String lang, RDFDatatype dtype) throws DatatypeFormatException(Code) | | Build a typed literal label from its value form. If the value is a string we
assume this is inteded to be a lexical form after all.
Parameters:
value - the value of the literal
Parameters:
lang - the optional language tag, only relevant for plain literals
Parameters:
dtype - the type of the literal, null for old style "plain" literals |
| LiteralLabel | | public LiteralLabel(String lex, Object value, String lang, RDFDatatype dtype)(Code) | | Build a typed literal label supplying both value and lexical form.
The caller guarantees that the lexical form is legal,
and the value corresponds.
Parameters:
lex - the lexical form of the literal
Parameters:
value - the value of the literal
Parameters:
lang - the optional language tag, only relevant for plain literals
Parameters:
dtype - the type of the literal, null for old style "plain" literals |
| LiteralLabel | | public LiteralLabel(Object value)(Code) | | Build a typed literal label from its value form using
whatever datatype is currently registered as the the default
representation for this java class. No language tag is supplied.
Parameters:
value - the literal value to encapsulate |
| LiteralLabel | | public LiteralLabel(String s, String lg, boolean xml)(Code) | | Old style constructor. Creates either a plain literal or an
XMLLiteral.
Parameters:
xml - If true then s is exclusive canonical XML of type rdf:XMLLiteral, and no checking will be invoked. |
| equals | | public boolean equals(Object other)(Code) | | Answer true iff this literal is syntactically equal to other.
Note: this is not sameValueAs.
|
| getDatatype | | public RDFDatatype getDatatype()(Code) | | Answer the datatype of this literal, null if it is untyped.
|
| getDatatypeURI | | public String getDatatypeURI()(Code) | | Answer the datatype URI of this literal, null if it untyped.
|
| getDefaultHashcode | | public int getDefaultHashcode()(Code) | | Answer the default hash value, suitable for datatypes which have values
which support hashCode() naturally: it is derived from its value if it is
well-formed and otherwise from its lexical form.
|
| getIndexingValue | | public Object getIndexingValue()(Code) | | Answer the value used to index this literal
TODO Consider pushing indexing decisions down to the datatype
|
| getLexicalForm | | public String getLexicalForm()(Code) | | Answer the lexical form of this literal, constructing it on-the-fly
(and remembering it) if necessary.
|
| getValue | | public Object getValue() throws DatatypeFormatException(Code) | | Answer a suitable instance of a Java class representing this literal's
value. May throw an exception if the literal is ill-formed.
|
| hashCode | | public int hashCode()(Code) | | Answer the hashcode of this literal, derived from its value if it's
well-formed and otherwise its lexical form.
|
| isWellFormed | | public boolean isWellFormed()(Code) | | Answer truee iff this is a well-formed literal.
|
| isXML | | public boolean isXML()(Code) | | Answer true iff this is a well-formed XML literal.
|
| language | | public String language()(Code) | | Answer the language associated with this literal (the empty string if
there's no language).
|
| normalize | | protected void normalize()(Code) | | Normalize the literal. If the value is narrower than the current data type
(e.g. value is xsd:date but the time is xsd:datetime) it will narrow
the type. If the type is narrower than the value then it may normalize
the value (e.g. set the mask of an XSDDateTime)
|
| sameValueAs | | public boolean sameValueAs(LiteralLabel other)(Code) | | Answer true iff this literal represents the same (abstract) value as
the other one.
|
| toString | | public String toString(boolean quoting)(Code) | | Answer a human-acceptable representation of this literal value.
This is NOT intended for a machine-processed result.
