Constructor Detail

StringEncodedValue

public StringEncodedValue(String name,
                          int expectedValueCount)

StringEncodedValue

public StringEncodedValue(String name,
                          int expectedValueCount,
                          boolean storeTwoDirections)

StringEncodedValue

public StringEncodedValue(String name,
                          int bits,
                          List<String> values,
                          boolean storeTwoDirections)

Method Detail

setString

public final void setString(boolean reverse,
                            IntsRef ref,
                            String value)

getString

public final String getString(boolean reverse,
                              IntsRef ref)

indexOf

public int indexOf(String value)

Parameters:

value - the String to retrieve the index

Returns:

the non-zero index of the String or 0 if it couldn't be found

getValues

public List<String> getValues()

Returns:

an unmodifiable List of the current values

equals

public boolean equals(Object obj)

Overrides:

equals in class UnsignedIntEncodedValue

getVersion

public int getVersion()

Description copied from interface: EncodedValue

The return value represents the state of this EncodedValue and it can be assumed that two JVMs return the same version when the EncodedValue has the same state unlike the hashCode method. Same version ensures compatibility when reading values.

Specified by:

getVersion in interface EncodedValue

Overrides:

getVersion in class UnsignedIntEncodedValue
