Constructor Detail

TripleIDInt

public TripleIDInt()

Basic constructor

TripleIDInt

public TripleIDInt(int subject,
                   int predicate,
                   int object)

Constructor

Parameters:

subject - The subject

predicate - The predicate

object - The object

TripleIDInt

public TripleIDInt(long subject,
                   long predicate,
                   long object)

TripleIDInt

public TripleIDInt(TripleIDInt other)

Build a TripleID as a copy of another one.

Parameters:

other -

TripleIDInt

public TripleIDInt(TripleID other)

Method Detail

getSubject

public int getSubject()

Returns:

the subject

setSubject

public void setSubject(int subject)

Parameters:

subject - the subject to set

getObject

public int getObject()

Returns:

the object

setObject

public void setObject(int object)

Parameters:

object - the object to set

getPredicate

public int getPredicate()

Returns:

the predicate

setPredicate

public void setPredicate(int predicate)

Parameters:

predicate - the predicate to set

setAll

public void setAll(int subject,
                   int predicate,
                   int object)

Replace all components of a TripleID at once. Useful to reuse existing objects.

Parameters:

subject -

predicate -

object -

assign

public void assign(TripleIDInt replacement)

clear

public void clear()

Set all components to zero.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(TripleIDInt other)

compareTo

public int compareTo(TripleIDInt other)

Compare TripleID to another one using SPO Order. To compare using other orders use TripleStringComparator

Specified by:

compareTo in interface Comparable<TripleIDInt>

match

public boolean match(TripleID pattern)

Check whether this triple matches a pattern of TripleID. 0 acts as a wildcard

Parameters:

pattern - The pattern to match against

Returns:

boolean

isEmpty

public boolean isEmpty()

Check whether all the components of the triple are empty (zero).

Returns:

isValid

public boolean isValid()

Check whether none of the components of the triple are empty.

Returns:

getPatternString

public String getPatternString()

Get the pattern of the triple as String, such as "SP?".

Returns:

asTripleID

public TripleID asTripleID()

size

public static int size()

size of one TripleID in memory
