所有已实现的接口:

java.io.Serializable, java.lang.Comparable<ResultMetadataType>
```
public enum ResultMetadataType
extends java.lang.Enum<ResultMetadataType>
```
Represents some type of metadata about the result of the decoding that the decoder wishes to communicate back to the caller.

枚举常量概要

枚举常量
枚举常量和说明
`BYTE_SEGMENTS` 2D barcode formats typically encode text, but allow for a sort of 'byte mode' which is sometimes used to encode binary data.
`ERROR_CORRECTION_LEVEL` Error correction level used, if applicable.
`ISSUE_NUMBER` For some periodicals, indicates the issue number as an `Integer`.
`ORIENTATION` Denotes the likely approximate orientation of the barcode in the image.
`OTHER` Unspecified, application-specific metadata.
`PDF417_EXTRA_METADATA` PDF417-specific metadata
`POSSIBLE_COUNTRY` For some products, the possible country of manufacture as a `String` denoting the ISO country code.
`STRUCTURED_APPEND_PARITY` If the code format supports structured append and the current scanned code is part of one then the parity is given with it.
`STRUCTURED_APPEND_SEQUENCE` If the code format supports structured append and the current scanned code is part of one then the sequence number is given with it.
`SUGGESTED_PRICE` For some products, indicates the suggested retail price in the barcode as a formatted `String`.
`UPC_EAN_EXTENSION` For some products, the extension text

- 枚举常量详细资料
  - OTHER
```
public static final ResultMetadataType OTHER
```
    Unspecified, application-specific metadata. Maps to an unspecified Object.
  - ORIENTATION
```
public static final ResultMetadataType ORIENTATION
```
    Denotes the likely approximate orientation of the barcode in the image. This value is given as degrees rotated clockwise from the normal, upright orientation. For example a 1D barcode which was found by reading top-to-bottom would be said to have orientation "90". This key maps to an Integer whose value is in the range [0,360).
  - BYTE_SEGMENTS
```
public static final ResultMetadataType BYTE_SEGMENTS
```
    2D barcode formats typically encode text, but allow for a sort of 'byte mode' which is sometimes used to encode binary data. While Result makes available the complete raw bytes in the barcode for these formats, it does not offer the bytes from the byte segments alone.
    
    This maps to a List of byte arrays corresponding to the raw bytes in the byte segments in the barcode, in order.
  - ERROR_CORRECTION_LEVEL
```
public static final ResultMetadataType ERROR_CORRECTION_LEVEL
```
    Error correction level used, if applicable. The value type depends on the format, but is typically a String.
  - ISSUE_NUMBER
```
public static final ResultMetadataType ISSUE_NUMBER
```
    For some periodicals, indicates the issue number as an Integer.
  - SUGGESTED_PRICE
```
public static final ResultMetadataType SUGGESTED_PRICE
```
    For some products, indicates the suggested retail price in the barcode as a formatted String.
  - POSSIBLE_COUNTRY
```
public static final ResultMetadataType POSSIBLE_COUNTRY
```
    For some products, the possible country of manufacture as a String denoting the ISO country code. Some map to multiple possible countries, like "US/CA".
  - UPC_EAN_EXTENSION
```
public static final ResultMetadataType UPC_EAN_EXTENSION
```
    For some products, the extension text
  - PDF417_EXTRA_METADATA
```
public static final ResultMetadataType PDF417_EXTRA_METADATA
```
    PDF417-specific metadata
  - STRUCTURED_APPEND_SEQUENCE
```
public static final ResultMetadataType STRUCTURED_APPEND_SEQUENCE
```
    If the code format supports structured append and the current scanned code is part of one then the sequence number is given with it.
  - STRUCTURED_APPEND_PARITY
```
public static final ResultMetadataType STRUCTURED_APPEND_PARITY
```
    If the code format supports structured append and the current scanned code is part of one then the parity is given with it.

  - values
```
public static ResultMetadataType[] values()
```
    按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示:
```
for (ResultMetadataType c : ResultMetadataType.values())
    System.out.println(c);
```
    返回:
    
    按照声明该枚举类型的常量的顺序返回的包含这些常量的数组
  - valueOf
```
public static ResultMetadataType valueOf(java.lang.String name)
```
    返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
    
    参数:
    
    name - 要返回的枚举常量的名称。
    
    返回:
    
    返回带有指定名称的枚举常量
    
    抛出:
    
    java.lang.IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
    
    java.lang.NullPointerException - 如果参数为空值
