Record Class PageEncodingStats

java.lang.Object

java.lang.Record

dev.hardwood.metadata.PageEncodingStats

Record Components:

pageType - the kind of page counted

encoding - the encoding those pages were written with

count - the number of pages written with this page type and encoding

public record PageEncodingStats(PageType pageType, Encoding encoding, int count)
extends Record

The number of pages a writer produced for one combination of page type and encoding within a column chunk.

A chunk's full set of these is available from ColumnMetaData.encodingStats(); the field is optional in the format, so it may be absent. When present it is complete: the counts account for every page in the chunk. A file that encodes the field in some other way than the format defines reads as absent rather than as a partial list.

public PageEncodingStats(PageType pageType,
 Encoding encoding,
 int count)

Creates an instance of a PageEncodingStats record class.

Parameters:

pageType - the value for the pageType record component

encoding - the value for the encoding record component

count - the value for the count record component

Method Details

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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:
