Class StructBuilder

java.lang.Object
com.google.mu.protobuf.util.StructBuilder
public final class StructBuilder extends Object
A builder that supports building heterogeneous Struct more conveniently, while eliding most of the intermediary and verbose Value creation.

Unlike Struct.Builder, the add() methods will throw upon duplicate keys.

      See MoreValues for helpers that create common ListValue conveniently.

    • add

      @CanIgnoreReturnValue public StructBuilder add(String name, Iterable<com.google.protobuf.Value> values)
      Adds a (name, values) field, with values wrapped in ListValue.
      Returns:
      this builder
      Throws:
      IllegalArgumentException - if name is duplicate

    • add

      @CanIgnoreReturnValue public StructBuilder add(String name, Map<String, com.google.protobuf.Value> map)
      Adds a (name, map) field. map is converted to a nested Struct.
      Returns:
      this builder
      Throws:
      IllegalArgumentException - if name is duplicate

    • add

      @CanIgnoreReturnValue public StructBuilder add(String name, com.google.protobuf.Struct struct)
      Adds a (name, struct) field.
      Returns:
      this builder
      Throws:
      IllegalArgumentException - if name is duplicate

      @CanIgnoreReturnValue public StructBuilder add(String name, StructBuilder struct)
      Adds a (name, struct) field.
      Returns:
      this builder
      Throws:
      IllegalArgumentException - if name is duplicate

    • add

      @CanIgnoreReturnValue public StructBuilder add(String name, com.google.protobuf.Value value)
      Adds a (name, value) field.

      To add a null value, use MoreValues.NULL as in add("name", NULL).

      Returns:
      this builder

    • addAll

      @CanIgnoreReturnValue public StructBuilder addAll(Map<String, com.google.protobuf.Value> map)
      Adds all key-value pairs from map into this builder.
      Returns:
      this builder
      Throws:
      IllegalArgumentException - if any key is duplicate

    • addAll

      @CanIgnoreReturnValue public StructBuilder addAll(Multimap<String, com.google.protobuf.Value> multimap)

      Returns:
      this builder
      Throws:
      IllegalArgumentException - if any key is duplicate

    • addAll

      @CanIgnoreReturnValue public StructBuilder addAll(Table<String, String, com.google.protobuf.Value> table)

      Returns:
      this builder
      Throws:
      IllegalArgumentException - if any row key is duplicate

    • addAllFields

      @CanIgnoreReturnValue public StructBuilder addAllFields(com.google.protobuf.Struct that)
