Parameters:

subject - The subject

predicate - The predicate

object - The object

public TripleString(TripleString other)

Copy constructor

Method Detail

getSubject

public CharSequence getSubject()

Returns:

the subject

setSubject

public void setSubject(CharSequence subject)

Parameters:

subject - the subject to set

getPredicate

public CharSequence getPredicate()

Returns:

the predicate

setPredicate

public void setPredicate(CharSequence predicate)

Parameters:

predicate - the predicate to set

getObject

public CharSequence getObject()

Returns:

the object

setObject

public void setObject(CharSequence object)

Parameters:

object - the object to set

setAll

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

Sets all components at once. Useful to reuse existing object instead of creating new ones for performance.

Parameters:

subject -

predicate -

object -

equals

public boolean equals(TripleString other)

match

public boolean match(TripleString pattern)

Check whether this triple matches a pattern. A pattern is just a TripleString where each empty component means any.

Parameters:

pattern -

Returns:

clear

public void clear()

Set all components to ""

isEmpty

public boolean isEmpty()

Checks whether all components are empty.

Returns:

hasEmpty

public boolean hasEmpty()

Checks whether any component is empty.

Returns:

read

public void read(String line)
          throws ParserException

Read from a line, where each component is separated by space.

Parameters:

line -

Throws:

ParserException

toString

public String toString()

Overrides:

toString in class Object

asNtriple

public CharSequence asNtriple()
                       throws IOException

Convert TripleString to NTriple

Throws:

IOException

dumpNtriple

public final void dumpNtriple(Appendable out)
                       throws IOException

Throws:

IOException
