Parameters:

columns - the value for the columns record component

bucketingVersion - the value for the bucketingVersion record component

tableBucketCount - the value for the tableBucketCount record component

readBucketCount - the value for the readBucketCount record component

sortedBy - the value for the sortedBy record component

Method Details

toTableBucketProperty

public HiveBucketProperty toTableBucketProperty()

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal.

the value of the bucketingVersion record component

tableBucketCount

public int tableBucketCount()

Returns the value of the tableBucketCount record component.

Returns:

the value of the tableBucketCount record component

readBucketCount

public int readBucketCount()

Returns the value of the readBucketCount record component.

Returns:

the value of the readBucketCount record component

sortedBy

public List<SortingColumn> sortedBy()

Returns the value of the sortedBy record component.
