Method Summary

All Methods Static Methods Instance Methods Concrete Methods Deprecated Methods
Modifier and Type	Method and Description
`Resource`	`asResource()`
`Triple`	`asTriple()`
`static Triple[]`	`asTriples(Statement[] statements)` returns an array of triples corresponding to the array of statements; ie the i'th element of the result is the i'th element of the input as a triple.
`static RDFNode`	`createObject(Node n, EnhGraph g)` create an RDF node which might be a literal, or not.
`ReifiedStatement`	`createReifiedStatement()` create a ReifiedStatement corresponding to this Statement
`ReifiedStatement`	`createReifiedStatement(String uri)` create a ReifiedStatement corresponding to this Statement and with the given _uri_.
`boolean`	`equals(Object o)` .equals() defers to .sameAs so we only get the complexity of one cast.
`Alt`	`getAlt()` Return the object of the statement.
`Bag`	`getBag()` Return the object of the statement.
`Literal`	`getLiteral()` get the object field of this statement, insisting that it be a Literal.
`RDFNode`	`getObject()` An accessor funtion to return the object of the statement.
`Property`	`getPredicate()` An accessor function to return the predicate of the statement.
`Statement`	`getProperty(Property p)` Get a property of the object of the statement.
`Resource`	`getResource()` Return the object of the statement.
`Resource`	`getResource(ResourceF f)` Deprecated.

`Statement`	`getStatementProperty(Property p)` Return a property of this statement.
`Resource`	`getSubject()` An accessor method to return the subject of the statements.
`int`	`hashCode()` Returns asTriple().hashCode()
`boolean`	`isReified()` Determine if this statement is the subject of any statements its associated model.
`RSIterator`	`listReifiedStatements()` answer an iterator which delivers all the reified statements in the model this Statement belongs to that match this Statement.
`Statement`	`remove()` Remove this statement from its associated model.
`void`	`removeReification()` Finds all possible resources which are the reification of this statement, and for each removes all four triples of the reification quad.

    Returns:
    
    The predicate of the statement.
  - getObject
```
public RDFNode getObject()
```
    Description copied from interface: Statement
    
    An accessor funtion to return the object of the statement.
    
    Specified by:
    
    getObject in interface Statement
    
    Specified by:
    
    getObject in class StatementBase
    
    Returns:
    
    Return the object of the statement.
  - getStatementProperty
```
public Statement getStatementProperty(Property p)
```
    Description copied from interface: Statement
    
    Return a property of this statement.
    The model associated with this statement is searched for a statement with this statement as subject and the specified property as predicate. If such a statement is found it is return. If more than one exists in the model, then it is undefined which is returned. If no such statement exists, an exception is thrown.
    
    Specified by:
    
    getStatementProperty in interface Statement
    
    Parameters:
    
    p - the property sought
    
    Returns:
    
    a statement representing an instance of the specified property.
  - getResource
```
public Resource getResource()
```
    Description copied from interface: Statement
    
    Return the object of the statement.
    An exception will be thrown if the object is not a resource.
    
    Specified by:
    
    getResource in interface Statement
    
    Specified by:
    
    getResource in class StatementBase
    
    Returns:
    
    The Resource which is the object of the statement.
  - getResource
```
@Deprecated
public Resource getResource(ResourceF f)
```
    Deprecated.
    
    Description copied from interface: Statement
    
    Return the object of the statement.
    An exception will be thrown if the object is not a Resource.
    
    Specified by:
    
    getResource in interface Statement
    
    Returns:
    
    The object of the statement.
  - getProperty
```
public Statement getProperty(Property p)
```
    Description copied from interface: Statement
    
    Get a property of the object of the statement.
    There is an unfortunate ambiguity here. GetProperty would normally treat the statement as a resource, and return a property about this statement. This is not what is wanted in most cases, so getProperty on a statement is defined to call getProperty on its object. If a property of the statement itself is required, getStatementProperty should be used.
    
    If the object of the statement is not a resource, an exception is thrown.
    
    Specified by:
    
    getProperty in interface Statement
    
    Parameters:
    
    p - the property sought
    
    Returns:
    
    a statement representing an instance of the required property
  - getLiteral
```
public Literal getLiteral()
```
    get the object field of this statement, insisting that it be a Literal. If it isn't, throw LiteralRequiredException.
    
    Specified by:
    
    getLiteral in interface Statement
    
    Specified by:
    
    getLiteral in class StatementBase
    
    Returns:
    
    The Literal which is the object of the statement.
  - getBag
```
public Bag getBag()
```
    Description copied from interface: Statement
    
    Return the object of the statement.
    An exception will be thrown if the object is not a Resource.
    
    Specified by:
    
    getBag in interface Statement
    
    Returns:
    
    The object of the statement interpreted as a value of the specified type.
  - getAlt
```
public Alt getAlt()
```
    Description copied from interface: Statement
    
    Return the object of the statement.
    An exception will be thrown if the object is not a Resource.
    
    Specified by:

    The object of the statement interpreted as a value of the specified type.
