Method Summary

Modifier and Type	Method and Description
boolean	addAllowed() Answer true if Graph::add() can be used to add at least some triples to the graph.
boolean	addAllowed(boolean everyTriple) Deprecated. To be removed
boolean	canBeEmpty() Deprecated. To be removed
boolean	deleteAllowed() Answer true iff Graph::delete() can be used to remove at least some triples from the graph.
boolean	deleteAllowed(boolean everyTriple) Deprecated. To be removed
boolean	findContractSafe() Deprecated. To be removed
boolean	handlesLiteralTyping() Answer true iff this graph compares literals for equality by value in find() operations, rather just applying RDFTerm equality.
boolean	iteratorRemoveAllowed() Deprecated. To be removed
boolean	sizeAccurate() Answer true iff Graph::size() is accurate.

Method Detail

sizeAccurate

boolean sizeAccurate()

Answer true iff Graph::size() is accurate.

addAllowed

boolean addAllowed()

Answer true if Graph::add() can be used to add at least some triples to the graph.

deleteAllowed

boolean deleteAllowed()

Answer true iff Graph::delete() can be used to remove at least some triples from the graph.

addAllowed

@Deprecated
boolean addAllowed(boolean everyTriple)

Deprecated. To be removed

Answer true if Graph::add() can be used to add at least some triples to the graph. If everyTriple is true, answer true iff *any* triple can be added (ie the graph places no special restrictions on triples).

deleteAllowed

@Deprecated
boolean deleteAllowed(boolean everyTriple)

Deprecated. To be removed

Answer true if Graph::delete() can be used to remove at least some triples from the graph. If everyTriple is true, any such triple may be removed.

iteratorRemoveAllowed

@Deprecated
boolean iteratorRemoveAllowed()

Deprecated. To be removed

Answer true iff the iterators returned from find support the .remove() operation.

canBeEmpty

@Deprecated
boolean canBeEmpty()

Deprecated. To be removed

Answer true iff the graph can be completely empty.

findContractSafe

@Deprecated
boolean findContractSafe()

Deprecated. To be removed

Answer true if the find() contract on the associated graph is "safe", ie, can be used safely by the pretty-printer (we'll tighten up that definition).

handlesLiteralTyping

boolean handlesLiteralTyping()

Answer true iff this graph compares literals for equality by value in find() operations, rather just applying RDFTerm equality. Only applies to GraphMem. TDB models have this effect because of canonicalization for certain datatypes and ranges, SDB models don't.
