java.lang.Object
- org.apache.lucene.util.PagedBytes

```
public final class PagedBytes
extends java.lang.Object
```
Represents a logical byte[] as a series of pages. You can write-once into the logical byte[] (append only), using copy, and then retrieve slices (BytesRef) into it using fill.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`copy(IndexInput in, long byteCount)`	Read this many bytes from in

public PagedBytes(int blockBits)
```
    1<<blockBits must be bigger than biggest single BytesRef slice that will be pulled
- Method Detail
  - copy
```
public void copy(IndexInput in,
                 long byteCount)
          throws java.io.IOException
```
    Read this many bytes from in
    
    Throws:
    
    java.io.IOException
  - copy
```
public void copy(BytesRef bytes,
                 BytesRef out)
```
    Copy BytesRef in, setting BytesRef out to the result. Do not use this if you will use freeze(true). This only supports bytes.length <= blockSize
  - freeze
```
public PagedBytes.Reader freeze(boolean trim)
```
    Commits final byte[], trimming it if necessary and if trim=true
  - getPointer
```
public long getPointer()
```
  - ramBytesUsed
```
public long ramBytesUsed()
```
    Return approx RAM usage in bytes.
  - copyUsingLengthPrefix
```
public long copyUsingLengthPrefix(BytesRef bytes)
```
    Copy bytes in, writing the length as a 1 or 2 byte vInt prefix.
  - getDataInput
```
public PagedBytes.PagedBytesDataInput getDataInput()
```
    Returns a DataInput to read values from this PagedBytes instance.
  - getDataOutput
```
public PagedBytes.PagedBytesDataOutput getDataOutput()
```
    Returns a DataOutput that you may use to write into this PagedBytes instance. If you do this, you should not call the other writing methods (eg, copy); results are undefined.
