Record Class PhysicalNode.Unnest

java.lang.Object

java.lang.Record

com.darkcollective.relix.plan.PhysicalNode.Unnest

All Implemented Interfaces:

PhysicalNode

Enclosing interface:

PhysicalNode

public static record PhysicalNode.Unnest(Schema schema, String column, boolean outer, Optional<String> ordinalityColumn, PhysicalNode input)
extends Record
implements PhysicalNode

Unnest (μ) — explodes the array-valued column into one row per element; outer keeps a NULL-bound row when the array is empty/missing. When ordinalityColumn is present (SQL WITH ORDINALITY), an extra NUMBER column of that name carries each element's 1-based position.

Constructor Details

Unnest

public Unnest(Schema schema,
 String column,
 boolean outer,
 Optional<String> ordinalityColumn,
 PhysicalNode input)

Creates an instance of a Unnest record class.

Parameters:

schema - the value for the schema record component

column - the value for the column record component

outer - the value for the outer record component

ordinalityColumn - the value for the ordinalityColumn record component

input - the value for the input record component

Method Details

children

public List<PhysicalNode> children()

Description copied from interface: PhysicalNode

Direct child plans, left-to-right; empty for a PhysicalNode.Scan.

Specified by:

children in interface PhysicalNode

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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

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.

schema

public Schema schema()

Returns the value of the schema record component.

Specified by:

schema in interface PhysicalNode

Returns:

the value of the schema record component

column

public String column()

Returns the value of the column record component.

Returns:

the value of the column record component

outer

public boolean outer()

Returns the value of the outer record component.

Returns:

the value of the outer record component

ordinalityColumn

public Optional<String> ordinalityColumn()

Returns the value of the ordinalityColumn record component.

Returns:

the value of the ordinalityColumn record component

input

public PhysicalNode input()

Returns the value of the input record component.

Returns:

the value of the input record component
