java.lang.Enum<AbstractMultipleParser.MetadataPolicy>

org.apache.tika.parser.multiple.AbstractMultipleParser.MetadataPolicy

All Implemented Interfaces:

Serializable, Comparable<AbstractMultipleParser.MetadataPolicy>

Enclosing class:

AbstractMultipleParser

public static enum AbstractMultipleParser.MetadataPolicy
extends Enum<AbstractMultipleParser.MetadataPolicy>

The various strategies for handling metadata emitted by multiple parsers. Note that not all will be supported by all subclasses.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DISCARD_ALL	Before moving onto another parser, throw away all previously seen metadata
FIRST_WINS	The first parser to output a given key wins, merge in non-clashing other keys
KEEP_ALL	Where multiple parsers output a given key, store all their different (unique) values
LAST_WINS	The last parser to output a given key wins, overriding previous parser values for a clashing key.

Method Summary

Modifier and Type	Method	Description
static AbstractMultipleParser.MetadataPolicy	valueOf(String name)	Returns the enum constant of this type with the specified name.
static AbstractMultipleParser.MetadataPolicy[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

DISCARD_ALL

public static final AbstractMultipleParser.MetadataPolicy DISCARD_ALL

Before moving onto another parser, throw away all previously seen metadata

FIRST_WINS

public static final AbstractMultipleParser.MetadataPolicy FIRST_WINS

The first parser to output a given key wins, merge in non-clashing other keys

LAST_WINS

public static final AbstractMultipleParser.MetadataPolicy LAST_WINS

The last parser to output a given key wins, overriding previous parser values for a clashing key.

KEEP_ALL

public static final AbstractMultipleParser.MetadataPolicy KEEP_ALL

Where multiple parsers output a given key, store all their different (unique) values

Method Detail

values

public static AbstractMultipleParser.MetadataPolicy[] 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 (AbstractMultipleParser.MetadataPolicy c : AbstractMultipleParser.MetadataPolicy.values())
    System.out.println(c);

Returns:

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

valueOf

public static AbstractMultipleParser.MetadataPolicy 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
