                          throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Read a 32-bit little-endian integer from the stream.
    
    Specified by:
    
    readRawLittleEndian32 in class CodedInputStream
    
    Throws:
    
    java.io.IOException
  - readRawLittleEndian64
```
public long readRawLittleEndian64()
                           throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Read a 64-bit little-endian integer from the stream.
    
    Specified by:
    
    readRawLittleEndian64 in class CodedInputStream
    
    Throws:
    
    java.io.IOException
  - enableAliasing
```
public void enableAliasing(boolean enabled)
```
    Description copied from class: CodedInputStream
    
    Enables ByteString aliasing of the underlying buffer, trading off on buffer pinning for data copies. Only valid for buffer-backed streams.
    
    Specified by:
    
    enableAliasing in class CodedInputStream
  - resetSizeCounter
```
public void resetSizeCounter()
```
    Description copied from class: CodedInputStream
    
    Resets the current size counter to zero (see CodedInputStream.setSizeLimit(int)). Only valid for InputStream-backed streams.
    
    Specified by:
    
    resetSizeCounter in class CodedInputStream
  - pushLimit
```
public int pushLimit(int byteLimit)
              throws InvalidProtocolBufferException
```
    Description copied from class: CodedInputStream
    
    Sets currentLimit to (current position) + byteLimit. This is called when descending into a length-delimited embedded message.
    Note that pushLimit() does NOT affect how many bytes the CodedInputStream reads from an underlying InputStream when refreshing its buffer. If you need to prevent reading past a certain point in the underlying InputStream (e.g. because you expect it to contain more data after the end of the message which you need to handle differently) then you must place a wrapper around your InputStream which limits the amount of data that can be read from it.
    
    Specified by:
    
    pushLimit in class CodedInputStream
    
    Returns:
    
    the old limit.
    
    Throws:
    
    InvalidProtocolBufferException
  - recomputeBufferSizeAfterLimit
```
private void recomputeBufferSizeAfterLimit()
```
  - popLimit
```
public void popLimit(int oldLimit)
```
    Description copied from class: CodedInputStream
    
    Discards the current limit, returning to the previous limit.
    
    Specified by:
    
    popLimit in class CodedInputStream
    
    Parameters:
    
    oldLimit - The old limit, as returned by pushLimit.
  - getBytesUntilLimit
```
public int getBytesUntilLimit()
```
    Description copied from class: CodedInputStream
    
    Returns the number of bytes to be read before the current limit. If no limit is set, returns -1.
    
    Specified by:
    
    getBytesUntilLimit in class CodedInputStream
  - isAtEnd
```
public boolean isAtEnd()
                throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Returns true if the stream has reached the end of the input. This is the case if either the end of the underlying input source has been reached or if the stream has reached a limit created using CodedInputStream.pushLimit(int). This function may get blocked when using StreamDecoder as it invokes tryRefillBuffer(int) in this function which will try to read bytes from input.
    
    Specified by:
    
    isAtEnd in class CodedInputStream
    
    Throws:
    
    java.io.IOException
  - getTotalBytesRead
```
public int getTotalBytesRead()
```
    Description copied from class: CodedInputStream
    
    The total bytes read up to the current position. Calling CodedInputStream.resetSizeCounter() resets this value to zero.
    
    Specified by:
    
    getTotalBytesRead in class CodedInputStream
  - refillBuffer
```
private void refillBuffer(int n)
                   throws java.io.IOException
```
    Reads more bytes from the input, making at least n bytes available in the buffer. Caller must ensure that the requested space is not yet available, and that the requested space is less than BUFFER_SIZE.
    
    Throws:
    
    InvalidProtocolBufferException - The end of the stream or the current limit was reached.
    
    java.io.IOException
  - tryRefillBuffer
```
private boolean tryRefillBuffer(int n)
                         throws java.io.IOException
```
    Tries to read more bytes from the input, making at least n bytes available in the buffer. Caller must ensure that the requested space is not yet available, and that the requested space is less than BUFFER_SIZE.
    
    Returns:
    
    true If the bytes could be made available; false 1. Current at the end of the stream 2. The current limit was reached 3. The total size limit was reached
    
    Throws:
    
    java.io.IOException
  - readRawByte
```
public byte readRawByte()
                 throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Read one byte from the input.
    
    Specified by:
    
    readRawByte in class CodedInputStream
    
    Throws:
    
    InvalidProtocolBufferException - The end of the stream or the current limit was reached.
    
    java.io.IOException
  - readRawBytes
```
public byte[] readRawBytes(int size)
                    throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Read a fixed size of bytes from the input.
    
    Specified by:
    
    readRawBytes in class CodedInputStream
    
    Throws:
    
    InvalidProtocolBufferException - The end of the stream or the current limit was reached.
    
    java.io.IOException
  - readRawBytesSlowPath
```
private byte[] readRawBytesSlowPath(int size,
                                    boolean ensureNoLeakedReferences)
                             throws java.io.IOException
```
    Exactly like readRawBytes, but caller must have already checked the fast path: (size <= (bufferSize - pos) && size > 0)
    If ensureNoLeakedReferences is true, the value is guaranteed to have not escaped to untrusted code.
    
    Throws:
    
    java.io.IOException
  - readRawBytesSlowPathOneChunk
```
private byte[] readRawBytesSlowPathOneChunk(int size)
                                     throws java.io.IOException
```
    Attempts to read the data in one byte array when it's safe to do. Returns null if the size to read is too large and needs to be allocated in smaller chunks for security reasons.
    Returns a byte[] that may have escaped to user code via InputStream APIs.
    
    Throws:
    
    java.io.IOException
  - readRawBytesSlowPathRemainingChunks
```
private java.util.List<byte[]> readRawBytesSlowPathRemainingChunks(int sizeLeft)
                                                            throws java.io.IOException
```
    Reads the remaining data in small chunks from the input stream.
    Returns a byte[] that may have escaped to user code via InputStream APIs.
    
    Throws:
    
    java.io.IOException
  - readBytesSlowPath
```
private ByteString readBytesSlowPath(int size)
                              throws java.io.IOException
```
    Like readBytes, but caller must have already checked the fast path: (size <= (bufferSize - pos) && size > 0 || size == 0)
    
    Throws:
    
    java.io.IOException
  - skipRawBytes
```
public void skipRawBytes(int size)
                  throws java.io.IOException
```
    Description copied from class: CodedInputStream
    
    Reads and discards size bytes.
    
    Specified by:
    
    skipRawBytes in class CodedInputStream
    
    Throws:
    
    InvalidProtocolBufferException - The end of the stream or the current limit was reached.

```
private void skipRawBytesSlowPath(int size)
                           throws java.io.IOException

    Exactly like skipRawBytes, but caller must have already checked the fast path: (size <= (bufferSize - pos) && size >= 0)
    
    Throws:
