com.facebook.presto.byteCode.expression.ByteCodeExpression
A ByteCodeExpression is chain of Java like expressions that results in at most a single value being pushed on the stack. The chain starts with a constant, local variable, static field, static method or invoke dynamic followed followed by zero or more invocations, field dereferences, array element fetches, or casts. The expression can optionally be terminated by a set expression, and in this case no value is pushed on the stack. A ByteCodeExpression is a ByteCodeNode so it works with tools like tree dump. This abstraction makes it easy to write generic byte code generators that can work with data that may come from a parameter, field or the result of a method invocation.
