Examples of EvalFactoryNode

com.espertech.esper.pattern.EvalFactoryNode
Superclass of all nodes in an evaluation tree representing an event pattern expression. Follows the Composite pattern. Child nodes do not carry references to parent nodes, the tree is unidirectional.

        {
            throw new ASTWalkException("Unexpected AST tree contains zero or more then 1 child elements for root");
        }


        // Get expression node sub-tree from the AST nodes placed so far
        EvalFactoryNode evalNode = astPatternNodeMap.values().iterator().next();


        PatternStreamSpecRaw streamSpec = new PatternStreamSpecRaw(evalNode, ViewSpec.EMPTY_VIEWSPEC_ARRAY, null, new StreamSpecOptions(), false, false);
        statementSpec.getStreamSpecs().add(streamSpec);
        statementSpec.setSubstitutionParameters(substitutionParamNodes);
