`BytesRef` `getBytesRef()` Retrieve this attribute's BytesRef.
`long` `getRawValue()` Returns current token's raw value as `long` with all `NumericTokenStream.NumericTermAttribute.getShift()` applied, undefined before first token
`int` `getShift()` Returns current shift value, undefined before first token
`int` `getValueSize()` Returns value size in bits (32 for `float`, `int`; 64 for `double`, `long`)
`int` `incShift()` Don't call this method!
`void` `init(long value, int valueSize, int precisionStep, int shift)` Don't call this method!

Constructor Detail

### NumericTokenStream.NumericTermAttributeImpl

    public NumericTokenStream.NumericTermAttributeImpl()

  Creates, but does not yet initialize this attribute instance

  See Also:
    `init(long, int, int, int)`

Method Detail

### getBytesRef

    public BytesRef getBytesRef()

  Description copied from interface: `TermToBytesRefAttribute`
  Retrieve this attribute's BytesRef. The bytes are updated from the current term when the consumer calls `TermToBytesRefAttribute.fillBytesRef()`.

  Specified by:
    `getBytesRef` in interface `TermToBytesRefAttribute`
  Returns:
    this Attributes internal BytesRef.

### fillBytesRef

    public int fillBytesRef()

  Description copied from interface: `TermToBytesRefAttribute`
  Updates the bytes `TermToBytesRefAttribute.getBytesRef()` to contain this term's final encoding, and returns its hashcode.

  Specified by:
    `fillBytesRef` in interface `TermToBytesRefAttribute`
  Returns:
    the hashcode as defined by `BytesRef.hashCode()`:

          int hash = 0;
          for (int i = termBytes.offset; i < termBytes.offset+termBytes.length; i++) {
            hash = 31*hash + termBytes.bytes[i];
          }

    Implement this for performance reasons, if your code can calculate the hash on-the-fly. If this is not the case, just return `termBytes.hashCode()`.

### getShift

    public int getShift()

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Returns current shift value, undefined before first token

  Specified by:
    `getShift` in interface `NumericTokenStream.NumericTermAttribute`

### setShift

    public void setShift(int shift)

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Don't call this method!

  Specified by:
    `setShift` in interface `NumericTokenStream.NumericTermAttribute`

### incShift

    public int incShift()

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Don't call this method!

  Specified by:
    `incShift` in interface `NumericTokenStream.NumericTermAttribute`

### getRawValue

    public long getRawValue()

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Returns current token's raw value as `long` with all `NumericTokenStream.NumericTermAttribute.getShift()` applied, undefined before first token

  Specified by:
    `getRawValue` in interface `NumericTokenStream.NumericTermAttribute`

### getValueSize

    public int getValueSize()

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Returns value size in bits (32 for `float`, `int`; 64 for `double`, `long`)

  Specified by:
    `getValueSize` in interface `NumericTokenStream.NumericTermAttribute`

### init

    public void init(long value,
                     int valueSize,
                     int precisionStep,
                     int shift)

  Description copied from interface: `NumericTokenStream.NumericTermAttribute`
  Don't call this method!

  Specified by:
    `init` in interface `NumericTokenStream.NumericTermAttribute`

### clear

    public void clear()

  Description copied from class: `AttributeImpl`
  Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.

  Specified by:
    `clear` in class `AttributeImpl`

### reflectWith

    public void reflectWith(AttributeReflector reflector)

  Description copied from class: `AttributeImpl`
  This method is for introspection of attributes, it should simply add the key/values this attribute holds to the given `AttributeReflector`.

  The default implementation calls `AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)` for all non-static fields from the implementing class, using the field name as key and the field value as value. The Attribute class is also determined by reflection. Please note that the default implementation can only handle single-Attribute implementations.

  Custom implementations look like this (e.g. for a combined attribute implementation):

         public void reflectWith(AttributeReflector reflector) {
           reflector.reflect(CharTermAttribute.class, "term", term());
           reflector.reflect(PositionIncrementAttribute.class, "positionIncrement", getPositionIncrement());
         }

  If you implement this method, make sure that for each invocation, the same set of `Attribute` interfaces and keys are passed to `AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)` in the same order, but possibly different values. So don't automatically exclude e.g. `null` properties!

  Overrides:
    `reflectWith` in class `AttributeImpl`
  See Also:
    `AttributeImpl.reflectAsString(boolean)`

### copyTo

    public void copyTo(AttributeImpl target)

  Description copied from class: `AttributeImpl`
  Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.

  Specified by:
    `copyTo` in class `AttributeImpl`
