Field Details

VERSION

@Deprecated(since="4.3.0",
            forRemoval=true)
public static final LongRioSetting VERSION

Deprecated, for removal: This API element is subject to removal in a future version.

Use BinaryRDFWriterSettings.VERSION instead.

Setting for the binary RDF format to use.

Defaults to 2.

Can be overridden by setting system property org.eclipse.rdf4j.rio.binary.format_version

BUFFER_SIZE

@Deprecated(since="4.3.0",
            forRemoval=true)
public static final LongRioSetting BUFFER_SIZE

Deprecated, for removal: This API element is subject to removal in a future version.

Use BinaryRDFWriterSettings.BUFFER_SIZE instead.

Setting for the number of statements to consider while analyzing duplicate RDF terms. Terms that occur twice or more within the buffer of statements are written out (starting from the second occurrence) as identifiers.

Defaults to 8192.

Can be overridden by setting system property org.eclipse.rdf4j.rio.binary.buffer_size

CHARSET

@Deprecated(since="4.3.0",
            forRemoval=true)
public static final StringRioSetting CHARSET

Deprecated, for removal: This API element is subject to removal in a future version.

Use BinaryRDFWriterSettings.CHARSET instead.

Setting for the character set to use for encoding strings (only applicable to version 2 of the binary RDF format).

Defaults to "UTF-8".

Can be overridden by setting system property org.eclipse.rdf4j.rio.binary.charset

RECYCLE_IDS

@Deprecated(since="4.3.0",
            forRemoval=true)
public static final BooleanRioSetting RECYCLE_IDS

Deprecated, for removal: This API element is subject to removal in a future version.

Use BinaryRDFWriterSettings.RECYCLE_IDS instead.

Setting for whether to recycle IDs while writing binary RDF files. (only applicable to version 2 of the binary RDF format).

If enabled (the default), once an RDF term is no longer referenced in the buffer of statements (see also BUFFER_SIZE), the ID of that term can be reused and any in memory reference to that term is released. If disabled, once an RDF term is assigned an ID it is never released and an in-memory reference to that term is maintained in memory. Note that disabling this setting may decrease file size, but also may result in an OutOfMemoryError because heap memory used is for every term that is ever assigned an ID.

Defaults to true.

Can be overridden by setting system property org.eclipse.rdf4j.rio.binary.recycle_ids
