truncateBinary
public static java.nio.ByteBuffer truncateBinary(java.nio.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 truncatedlength
- The non-negative length to truncate input to
-
truncateBinaryUnsafe
public static java.nio.ByteBuffer truncateBinaryUnsafe(java.nio.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 truncatedwidth
- The non-negative length to truncate input to
-
truncateBinaryMin
public static Literal<java.nio.ByteBuffer> truncateBinaryMin(Literal<java.nio.ByteBuffer> input, int length)
Returns a byte buffer whose length is lesser than or equal to truncateLength and is lower than the given input
