Record Class StructConstruction

java.lang.Record

com.darkcollective.relix.ast.StructConstruction

Record Components:

fields - the ordered struct fields; must not be null

location - the source location of this operand; never null

All Implemented Interfaces:

Operand

public record StructConstruction(List<StructConstruction.Field> fields, SourceLocation location)
extends Record
implements Operand

Constructs a nested struct value in a projection — { name: expr, … }.

Each StructConstruction.Field pairs a field name with an operand expression. The shorthand { id, name } (a bare identifier with no :) is sugar for { id: id, name: name } and is desugared by the parser into explicit fields, so this node always carries explicit name → value pairs.

Together with ArrayConstruction and the COLLECT aggregate this lets a query reshape data nested → flat → nested.

Constructor Details

StructConstruction

public StructConstruction(List<StructConstruction.Field> fields,
 SourceLocation location)

Creates an instance of a StructConstruction record class.

Parameters:

fields - the value for the fields record component

location - the value for the location record component

StructConstruction

public StructConstruction(List<StructConstruction.Field> fields)

Convenience constructor for tests; uses SourceLocation.UNKNOWN.

Method Details

accept

public <R> R accept(OperandVisitor<R> visitor)

Specified by:

accept in interface Operand

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.

fields

public List<StructConstruction.Field> fields()

Returns the value of the fields record component.

Returns:

the value of the fields record component

location

public SourceLocation location()

Returns the value of the location record component.

Specified by:

location in interface Operand

Returns:

the value of the location record component
