Example 19 with TruffleBoundary

use of com.oracle.truffle.api.CompilerDirectives.TruffleBoundary in project graal by oracle.

the class SLStatementNode method getSourceSection.

/*
     * The creation of source section can be implemented lazily by looking up the root node source
     * and then creating the source section object using the indices stored in the node. This avoids
     * the eager creation of source section objects during parsing and creates them only when they
     * are needed. Alternatively, if the language uses source sections to implement language
     * semantics, then it might be more efficient to eagerly create source sections and store it in
     * the AST.
     *
     * For more details see {@link InstrumentableNode}.
