Method Detail

optimize

CelAbstractSyntaxTree optimize(CelAbstractSyntaxTree ast)
                        throws CelOptimizationException

Performs custom optimization of the provided AST.

This invokes all the AST optimizers present in this CelOptimizer instance via CelOptimizerBuilder.addAstOptimizers(dev.cel.optimizer.CelAstOptimizer...) in their added order. Any exceptions thrown within the AST optimizer will be propagated to the caller and will abort the optimization process.

Note that the produced expression string from unparsing an optimized AST will likely not be equal to the original expression.

Parameters:

ast - A type-checked AST.

Throws:

CelOptimizationException - If any failures occur during any of the AST optimization pass.
