Record Class CatalogSnapshot.Entry

java.lang.Record

com.darkcollective.relix.semantic.CatalogSnapshot.Entry

Record Components:

connection - the declared connection's name

table - the table name within it, as the script spells it

schema - the heading, when this observation carries one

statistics - the statistics, when this observation carries them

origin - where the observation came from

captured - when it was made

Enclosing class:

CatalogSnapshot

public static record CatalogSnapshot.Entry(String connection, String table, Optional<Schema> schema, Optional<RelationStatistics> statistics, CatalogSnapshot.Origin origin, Instant captured)
extends Record

One observation of one table.

Both halves are optional and independently so: introspection may yield a schema and no statistics (a table it could describe but not count), and a run yields statistics and no schema.

Entry

public Entry(String connection,
 String table,
 Optional<Schema> schema,
 Optional<RelationStatistics> statistics,
 CatalogSnapshot.Origin origin,
 Instant captured)

Creates an instance of a Entry record class.

Parameters:

connection - the value for the connection record component

table - the value for the table record component

schema - the value for the schema record component

statistics - the value for the statistics record component

origin - the value for the origin record component

captured - the value for the captured 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

Returns:

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. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

connection

public String connection()

Returns the value of the connection record component.

Returns:

the value of the connection record component

table

public String table()

Returns the value of the table record component.

Returns:

the value of the table record component

schema

public Optional<Schema> schema()

Returns the value of the schema record component.

Returns:

the value of the schema record component

statistics

public Optional<RelationStatistics> statistics()

Returns the value of the statistics record component.

Returns:

the value of the statistics record component

origin

public CatalogSnapshot.Origin origin()

Returns the value of the origin record component.

Returns:

the value of the origin record component

captured

public Instant captured()

Returns the value of the captured record component.

Returns:

the value of the captured record component
