Methods

Constructor Statement (line 51)

The parameters to constructor are instances of classes and not just strings

throws: PhpError

Statement Statement (object node $subj, object node $pred, object node $obj)

object node $subj
object node $pred
object node $obj

compare (line 241)

Compares two statements and returns integer less than, equal to, or greater than zero.

Can be used for writing sorting function for models or with the PHP function usort().

access: public

boolean compare (object statement &$that)

object statement &$that

equals (line 217)

Checks if two statements are equal.

Two statements are considered to be equal if they have the same subject, predicate and object. A statement can only be equal to another statement object.

access: public

boolean equals (object statement $that)

object statement $that

getLabelObject (line 203)

Reurns the URI, text or bNode identifier of the statements's object.

access: public

string getLabelObject ()

getLabelPredicate (line 193)

Returns the URI of the statements's predicate.

access: public

string getLabelPredicate ()

getLabelSubject (line 183)

Returns the URI or bNode identifier of the statements's subject.

access: public

string getLabelSubject ()

getObject (line 97)

Returns the object of the triple.

access: public

object node getObject ()

getPredicate (line 88)

Returns the predicate of the triple.

access: public

object node getPredicate ()

getSubject (line 79)

Returns the subject of the triple.

access: public

object node getSubject ()

hashCode (line 132)

Retruns the hash code of the triple.

access: public

string hashCode ()

object (line 124)

Alias for getObject()

access: public

object node object ()

predicate (line 115)

Alias for getPredicate()

access: public

object node predicate ()

reify (line 257)

Reifies a statement.

Returns a new MemModel that is the reification of the statement. For naming the statement's bNode a Model or bNodeID must be passed to the method.

access: public

object model &reify (mixed &$model_or_bNodeID)

mixed &$model_or_bNodeID

subject (line 106)

Alias for getSubject()

access: public

object node subject ()

toString (line 142)

Dumps the triple.

access: public

string toString ()

Redefinition of:

Object::toString(): Serializes a object into a string

toStringObject (line 173)

Reurns a toString() serialization of the statements's object.

access: public

string toStringObject ()

toStringPredicate (line 163)

Returns a toString() serialization of the statements's predicate.

access: public

string toStringPredicate ()

toStringSubject (line 153)

Returns a toString() serialization of the statements's subject.

access: public

string toStringSubject ()
