Enum Constant Summary

Enum Constants

Enum Constant and Description
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

Enum Constant Detail

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.

Method Detail

values

public static ResultMetadataType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ResultMetadataType c : ResultMetadataType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ResultMetadataType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
