Method Detail

asValue

public final V asValue(LexiconRelation lex)

Operation is not supported because this IV type is not 100% inline. You MUST explicitly set the value cache.

If the value is not already cached, then inflate an inline RDF value to a BigdataValue and cache it on a private field.

Note: Query plans are responsible for ensuring that IVs have been materialized before operators are evaluated which invoke this method. This pattern ensures that efficient batch operators are used to materialize Values, and thereby avoids heavy RMI overhead in scale-out, and provides operators which use IVCache.getValue() with a simple method signature which does not require access to the lexicon. Query plans are also responsible for dropping variables once they are no longer needed or, in the case of large values and BLOBs, dropping the cached BigdataValue when possible in order to avoid excess network and heap overhead.

Specified by:

asValue in interface IVCache<V extends BigdataValue,T>

Parameters:

lex - The lexicon relation (this is required in order to access the BigdataValueFactory for the namespace associated with lexicon when we materialize an inline IV).

Returns:

The corresponding BigdataValue.

AbstractIV.setValue(BigdataValue)

getInlineValue

public final T getInlineValue()

Operation is not supported because this IV type is not 100% inline.

Specified by:

getInlineValue in interface IV<V extends BigdataValue,T>

Returns:

The Object.

isInline

Always returns false since the RDF value is not inline.
