Method Detail

values

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

Returns:

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

valueOf

public static IndexWriterSetting 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

applySetting

public void applySetting(org.apache.lucene.index.IndexWriterConfig writerConfig,
                         int value)

Throws:

IllegalArgumentException - when user selects an invalid value; should be wrapped.

applySetting

public void applySetting(org.apache.lucene.index.LogByteSizeMergePolicy logByteSizeMergePolicy,
                         int value)

Throws:

IllegalArgumentException - when user selects an invalid value; should be wrapped.

getKey

public String getKey()

Returns:

The key used in configuration files to select an option.

parseVal

public Integer parseVal(String value)

Specific parameters may override to provide additional keywords support.

Parameters:

value - the string value as in configuration file

Returns:

the integer value going to be set as parameter

Throws:

SearchException - for unrecognized values
