Example 5 with Script

use of org.apache.commons.jexl3.internal.Script in project commons-jexl by apache.

the class Closure method setCaptured.

/**
 * Sets the captured index of a given symbol, ie the target index of a parent
 * captured symbol in this closure's frame.
 * <p>This is meant to allow a locally defined function to "see" and call
 * itself as a local (captured) variable;
 * in other words, this allows recursive call of a function.
 * @param symbol the symbol index (in the caller of this closure)
 * @param value the value to set in the local frame
 */

    if (script instanceof ASTJexlLambda) {
