Binds an input expression to a given input schema
Binds an input expression to a given input schema
Canonicalizes an input expression.
Canonicalizes an input expression. Used to avoid double caching expressions that differ only cosmetically.
Generates a class for a given input expression.
Generates a class for a given input expression. Called when there is not cached code already available.
Generates the requested evaluator given already bound expression(s).
Generates the requested evaluator given already bound expression(s).
Generates the requested evaluator binding the given expression(s) to the inputSchema.
Generates the requested evaluator binding the given expression(s) to the inputSchema.
Create a new codegen context for expression evaluator, used to store those expressions that don't support codegen

Generates byte code that produces a InternalRow object that can update itself based on a new input InternalRow for a fixed set of Expressions. It exposes a
target
method, which is used to set the row that will be updated. The internal InternalRow object created internally is used only whentarget
is not used.
