Field Detail

QUERY_STRING

static final String QUERY_STRING

The original query from which this AST was generated.

Constant Field Values

PARSE_TREE

static final String PARSE_TREE

The parse tree generated from the query string (optional). For the default integration, this is the parse tree assembled by the Sesame sparql.jjt grammar. Other integrations may produce different parse trees using different object models.

Note: There is no guarantee that the parse tree is a serializable object. It may not need to be stripped off of the QueryRoot if the QueryRoot is persisted or shipped to another node in a cluster.

Constant Field Values

ORIGINAL_AST

static final String ORIGINAL_AST

The AST as received from the parser. This is either a QueryRoot or an UpdateRoot.

Constant Field Values

OPTIMIZED_AST

static final String OPTIMIZED_AST

The AST as rewritten by the IASTOptimizers.

Constant Field Values

QUERY_PLAN

static final String QUERY_PLAN

The physical query plan (pipeline bops).

Constant Field Values

OPTIMIZED_AST_BINDING_SETS

static final String OPTIMIZED_AST_BINDING_SETS

The incoming binding set associated with the query plan, as resulting from the query optimization phase.

Constant Field Values

QUERY_PARSE_TIME

static final String QUERY_PARSE_TIME

The parsing time for the query (nanoseconds).

See Also:

Constant Field Values

RESOLVE_VALUES_TIME

static final String RESOLVE_VALUES_TIME

The time to batch resolve RDF Values in the query to BigdataValues in the database (nanoseconds).

Constant Field Values

RESOLVED

static final String RESOLVED

Flag which indicates completed resolution of IVs. Used to prevent running resolution again on consequent calls to query.evaluate
