Class AttributesMap

  • All Implemented Interfaces:
    Attributes, java.io.Serializable, java.lang.Cloneable, java.util.Map<AttributeKey<?>,​java.lang.Object>
    public final class AttributesMap
extends java.util.HashMap<AttributeKey<?>,​java.lang.Object>
implements Attributes
    A map with a fixed capacity that drops attributes when the map gets full, and which truncates string and array string attribute values to the lengthLimit.

    This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.
