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.

static final String OPTIMIZED_AST

The AST as rewritten by the IASTOptimizers.
