Method Detail

newInstance

public static AGMaterializer newInstance()

Gets a default materializer that can be further configured.

See also the HTTP protocol documentation for materializing entailed triples.

Returns:

a default materializer.

withRuleset

public void withRuleset(String ruleset)

Adds a ruleset to be used during materialization.

See also the HTTP protocol documentation for materializing entailed triples.

Parameters:

ruleset - the name of the ruleset to include.

getWithRulesets

public List<String> getWithRulesets()

Gets the included rulesets.

Returns:

the with rulesets

withoutRuleset

public void withoutRuleset(String ruleset)

Excludes a ruleset from materialization.

See also the HTTP protocol documentation for materializing entailed triples.

Parameters:

ruleset - the name of the ruleset to exclude.

getWithoutRulesets

public List<String> getWithoutRulesets()

Gets the excluded rulesets.

Returns:

the without rulesets

getCommitPeriod

public Integer getCommitPeriod()

Gets the commit period for materialized triples.

See also the HTTP protocol documentation for materializing entailed triples.

Returns:

the commit period in triples.

setCommitPeriod

public void setCommitPeriod(Integer periodInTriples)

Sets the commit period for materialized triples.

Useful for limiting the back-end's memory usage during a large materialization. When periodInTriples is null (the default), the server's default setting is used.

See also the HTTP protocol documentation for materializing entailed triples.

Parameters:

periodInTriples - commit every time this many triples are added

getUseTypeSubproperty

public Boolean getUseTypeSubproperty()

Gets the useTypeSubproperty flag.

See also the HTTP protocol documentation for materializing entailed triples.

Returns:

the current setting

setUseTypeSubproperty

public void setUseTypeSubproperty(Boolean use)

Sets the useTypeSubproperty flag.

When use is null (the default), the server's default setting is used.

See also the HTTP protocol documentation for materializing entailed triples.

Parameters:

use - true when using this inference

getInferredGraph

public Resource getInferredGraph()

Gets the graph the inferred triples will be placed in.

If the value is null (the default), triples will be placed in the default graph.

Returns:

Graph URI or null (meaning 'the default graph')

setInferredGraph

public void setInferredGraph(Resource inferredGraph)

Sets the the graph the inferred triples will be placed in.

Parameters:

inferredGraph - Graph URI or null (meaning 'the default graph')
