Method Detail

getTermId

long getTermId()

Return the term identifier for this value. The term identifier uniquely identifies a Value for a database. Sometimes a TempTripleStore will be used that shares the lexicon with a given database, in which case the same term identifiers will be value for that TempTripleStore.

setTermId

void setTermId(long termId)

Set the term identifier for this value.

Parameters:

termId - The term identifier.

Throws:

IllegalArgumentException - if termId is NULL.

IllegalStateException - if the term identifier is already set to a different non-NULL value.

clearTermId

void clearTermId()

Clears the term identifier to NULL.
