public interface IndexableField
```
Represents a single field for indexing. IndexWriter consumes Iterable<IndexableField> as a document.

WARNING: This API is experimental and might change in incompatible ways in the next release.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`BytesRef`	`binaryValue()`	Non-null if this field has a binary value
`IndexableFieldType`	`fieldType()`	`IndexableFieldType` describing the properties of this field.
`default CharSequence`	`getCharSequenceValue()`	Non-null if this field has a string value
`String`	`name()`	Field name
`Number`	`numericValue()`	Non-null if this field has a numeric value
`Reader`	`readerValue()`	Non-null if this field has a Reader value
`String`	`stringValue()`	Non-null if this field has a string value
`TokenStream`	`tokenStream(Analyzer analyzer, TokenStream reuse)`	Creates the TokenStream used for indexing this field.

- Method Detail
  - name
```
String name()
```
    Field name
  - fieldType
```
IndexableFieldType fieldType()
```
    IndexableFieldType describing the properties of this field.
  - tokenStream
```
TokenStream tokenStream(Analyzer analyzer,
                        TokenStream reuse)
```
    Creates the TokenStream used for indexing this field. If appropriate, implementations should use the given Analyzer to create the TokenStreams.
    
    Parameters:
    
    analyzer - Analyzer that should be used to create the TokenStreams from
    
    reuse - TokenStream for a previous instance of this field name. This allows custom field types (like StringField and NumericField) that do not use the analyzer to still have good performance. Note: the passed-in type may be inappropriate, for example if you mix up different types of Fields for the same field name. So it's the responsibility of the implementation to check.
    
    Returns:
    
    TokenStream value for indexing the document. Should always return a non-null value if the field is to be indexed
  - binaryValue
```
BytesRef binaryValue()
```
    Non-null if this field has a binary value
  - stringValue
```
String stringValue()
```
    Non-null if this field has a string value
  - getCharSequenceValue
```
default CharSequence getCharSequenceValue()
```
    Non-null if this field has a string value
  - readerValue
```
Reader readerValue()
```
    Non-null if this field has a Reader value
  - numericValue
```
Number numericValue()
```
    Non-null if this field has a numeric value
