Enum Constant Detail

NO

public static final Field.TermVector NO
Do not store term vectors.


YES

public static final Field.TermVector YES
Store the term vectors of each document. A term vector is a list of the document's terms and their number of occurrences in that document.


WITH_POSITIONS

public static final Field.TermVector WITH_POSITIONS
Store the term vector + token position information

See Also:
YES

WITH_OFFSETS

public static final Field.TermVector WITH_OFFSETS
Store the term vector + Token offset information

See Also:
YES

WITH_POSITIONS_OFFSETS

public static final Field.TermVector WITH_POSITIONS_OFFSETS
Store the term vector + Token position and offset information

See Also:
YES, WITH_POSITIONS, WITH_OFFSETS
Method Detail

values

public static final Field.TermVector[] values()
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:
for(Field.TermVector c : Field.TermVector.values())
        System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they're declared

valueOf

public static Field.TermVector 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

toTermVector

public static Field.TermVector toTermVector(boolean stored,
                                            boolean withOffsets,
                                            boolean withPositions)
Get the best representation of a TermVector given the flags.


isStored
