- Method Detail
  - stringReader
```
public static Reader<String> stringReader(Charset charset)
```
    For basic charsets, returns a cached StringContentReader instance or create a new instance otherwise.
    
    Parameters:
    
    charset - the charset to use with the returned string content reader
    
    Returns:
    
    a string content reader
  - byteArrayReader
```
public static Reader<byte[]> byteArrayReader()
```
    The returned reader provides means to convert a ByteBuffer publisher to an array of bytes.
    Returns a lazily initialized classloader-scoped singleton.
    Note that the singleton aspect is not guarantied by all JVMs. Although, Oracle JVM does create a singleton because the lambda does not capture values.
    
    Returns:
    
    the byte array content reader singleton that transforms a publisher of byte buffers to a completion stage that might end exceptionally with IllegalArgumentException if it wasn't possible to convert the byte buffer to an array of bytes
  - inputStreamReader
```
public static Reader<InputStream> inputStreamReader()
```
    Creates a reader that bridges Flow API IO to a blocking Java InputStream. The resulting CompletionStage is already completed; however, the referenced InputStream in it may not already have all the data available; in such case, the read method (e.g., InputStream.read()) block.
    
    Returns:
    
    a input stream content reader
