Class BuilderELResolver

java.lang.Object

javax.el.ELResolver

com.github.protobufel.el.BuilderELResolver

Direct Known Subclasses:

MessageELResolver

public class BuilderELResolver
extends javax.el.ELResolver

ProtoBuf Builder ELResolver, like MapELResolver with field name or FieldDescriptor as a key.

• the field can be either a String, or a FieldDescriptor
• getValue(javax.el.ELContext, java.lang.Object, java.lang.Object) returns a special wrapper for the repeated field, either IRepeatedFieldValueBuilder for a primitive field, or IRepeatedFieldMessageBuilder for a Message type field; and delegates to the underlying Message.Builder in case of a singular field
• setValue(javax.el.ELContext, java.lang.Object, java.lang.Object, java.lang.Object) delegates to to the underlying Message.Builder
