package com.fasterxml.jackson.core;

import com.fasterxml.jackson.core.util.JacksonFeature;

 * Set of on/off capabilities that a {@link JsonGenerator} for given format
 * (or in case of buffering, original format) has.
 * Used in some cases to adjust aspects of things like content conversions and
 * coercions by format-agnostic functionality.
 * Specific or expected usage documented by individual capability entry Javadocs.
 * @since 2.12
public enum StreamWriteCapability
    implements JacksonFeature
     * Capability that indicates that the data format is able to express binary
     * data natively, without using textual encoding like Base64.
     * Capability is currently enabled for all binary formats and none of textual
     * formats.

     * Capability that indicates that the data format is able to write
     * "formatted numbers": that is, output of numbers is done as Strings
     * and caller is allowed to pass in logical number values as Strings.
     * Capability is currently enabled for most textual formats and none of binary
     * formats.

     * Whether feature is enabled or disabled by default.
