IRI (Eclipse RDF4J 4.2.4)

All Superinterfaces:

Resource, Serializable, Value

All Known Implementing Classes:

AbstractIRI, InternedIRI, LmdbIRI, MemIRI, NativeIRI, SimpleIRI
```
public interface IRI
extends Resource
```
An Internationalized Resource Identifier (IRI). IRIs may contain characters from the Universal Character Set (Unicode/ISO 10646), including Chinese or Japanese kanji, Korean, Cyrillic characters, and so forth. It is defined by RFC 3987.
An IRI can be split into a namespace part and a local name part, which are derived from an IRI string by splitting it in two using the following algorithm:
- Split after the first occurrence of the '#' character,
- If this fails, split after the last occurrence of the '/' character,
- If this fails, split after the last occurrence of the ':' character.
The last step should never fail as every legal (full) IRI contains at least one ':' character to separate the scheme from the rest of the IRI. The implementation should check this upon object creation.

- Method Detail
  - isIRI
```
default boolean isIRI()
```
    Description copied from interface: Value
    
    Check if the object is an instance of the given type. Typically 2x than using instanceof.
    For implementers: This default implementation is overridden in the repsective sub-interface.
    
    Specified by:
    
    isIRI in interface Value
    
    Returns:
    
    true if instance of IRI
  - getNamespace
```
String getNamespace()
```
    Gets the namespace part of this IRI.
    The namespace is defined as per the algorithm described in the class documentation.
    
    Returns:
    
    the namespace of this IRI
  - getLocalName
```
String getLocalName()
```
    Gets the local name part of this IRI.
    The local name is defined as per the algorithm described in the class documentation.
    
    Returns:
    
    the local name of this IRI
  - equals
```
boolean equals(Object o)
```
    Compares this IRI to another object.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the object to compare this IRI to
    
    Returns:
    
    true, if the other object is an instance of IRI and their string values are equal; false, otherwise
  - hashCode
```
int hashCode()
```
    Computes the hash code of this IRI.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code for this IRI computed as Value.stringValue().hashCode()
