Class ExpressionFactory

java.lang.Object

org.glassfish.pfl.dynamic.codegen.impl.ExpressionFactory

public final class ExpressionFactory
extends Object

Used to create all expressions. BlockStatement is used as the factory for creating instances of ExpressionFactory. All statements created by an ExpressionFactory have the BlockStatement that created this ExpressionFactory as their parent. An ExpressionFactory should be used only to create Expression instances in statements inside the creating BlockStatement. Each subtype of Expression is defined as a static inner class in ExpressionFactory.
