GenericPartitionFieldSummary

public GenericPartitionFieldSummary(boolean containsNull,
 boolean containsNaN,
 ByteBuffer lowerBound,
 ByteBuffer upperBound)

Method Details

containsNull

public boolean containsNull()

Description copied from interface: ManifestFile.PartitionFieldSummary

Returns true if at least one file in the manifest has a null value for the field.

Specified by:

containsNull in interface ManifestFile.PartitionFieldSummary

containsNaN

public Boolean containsNaN()

Description copied from interface: ManifestFile.PartitionFieldSummary

Returns true if at least one file in the manifest has a NaN value for the field. Null if this information doesn't exist.

Default to return null to ensure backward compatibility.

Specified by:

containsNaN in interface ManifestFile.PartitionFieldSummary

lowerBound

public ByteBuffer lowerBound()

Description copied from interface: ManifestFile.PartitionFieldSummary

Returns a ByteBuffer that contains a serialized bound lower than all values of the field.

Specified by:

lowerBound in interface ManifestFile.PartitionFieldSummary

upperBound

public ByteBuffer upperBound()

Description copied from interface: ManifestFile.PartitionFieldSummary

Returns a ByteBuffer that contains a serialized bound higher than all values of the field.

Specified by:

upperBound in interface ManifestFile.PartitionFieldSummary

size
