@NotThreadSafe
public static final class ImmutableArrayReducerOperator.Builder<T>
extends Object
Builds instances of type
ImmutableArrayReducerOperator.
Initialize attributes and then invoke the build() method to create an
immutable instance.
Builder is not thread-safe and generally should not be stored in a field or collection,
but instead used immediately to create instances.

from
@CanIgnoreReturnValue public final ImmutableArrayReducerOperator.Builder<T> from(ArrayReducerOperator<T> instance) Fill a builder with attribute values from the providedArrayReducerOperatorinstance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values.- Parameters:
instance- The instance from which to copy values- Returns:
thisbuilder for use in a chained invocation
-
reducer
@CanIgnoreReturnValue public final ImmutableArrayReducerOperator.Builder<T> reducer(BinaryOperator<T> reducer) Initializes the value for thereducerattribute.- Parameters:
reducer- The value for reducer- Returns:
thisbuilder for use in a chained invocation
-
arrayExpression
@CanIgnoreReturnValue public final ImmutableArrayReducerOperator.Builder<T> arrayExpression(Expression arrayExpression) Initializes the value for thearrayExpressionattribute.- Parameters:
arrayExpression- The value for arrayExpression- Returns:
thisbuilder for use in a chained invocation
-
placeholderValue
@CanIgnoreReturnValue public final ImmutableArrayReducerOperator.Builder<T> placeholderValue(@Nullable Object placeholderValue) Initializes the value for theplaceholderValueattribute.If not set, this attribute will have a default value as returned by the initializer of
placeholderValue.- Parameters:
placeholderValue- The value for placeholderValue (can benull)- Returns:
thisbuilder for use in a chained invocation
-
build
Builds a newImmutableArrayReducerOperator.- Returns:
- An immutable instance of ArrayReducerOperator
- Throws:
IllegalStateException- if any required attributes are missing
