Method Details
- truncateBinary
  
  public static ByteBuffer truncateBinary(ByteBuffer input, int length)
  
  Truncates the input byte buffer to the given length.
  We allow for a length of zero so that rows with empty string can be evaluated. Partition specs still cannot be created with a length of zero due to a constraint when parsing column truncation specs in org.apache.iceberg.MetricsModes.
  
  Parameters:
  
  input - The ByteBuffer to be truncated
  
  length - The non-negative length to truncate input to
- truncateBinaryUnsafe
  
  public static ByteBuffer truncateBinaryUnsafe(ByteBuffer value, int width)
  
  Truncates the input byte buffer to the given length.
  Unlike truncateBinary(ByteBuffer, int), this skips copying the input data.
  
  Parameters:
  
  value - The ByteBuffer to be truncated
  
  width - The non-negative length to truncate input to
- truncateBinaryMin
  
  public static Literal<ByteBuffer> truncateBinaryMin(Literal<ByteBuffer> input, int length)
  
  Returns a byte buffer whose length is lesser than or equal to truncateLength and is lower than the given input
- truncateBinaryMax
  
  public static Literal<ByteBuffer> truncateBinaryMax(Literal<ByteBuffer> input, int length)
  
  Returns a byte buffer whose length is lesser than or equal to truncateLength and is greater than the given input
