technology.sola.script.parser.Expr.NullishCoalescence

Record Components:

left - the left side expression to operate on

operator - the Token for the nullish coalescence operator

right - the right side expression to operate on

All Implemented Interfaces:

Expr

Enclosing interface:

Expr

public static record Expr.NullishCoalescence(Expr left, Token operator, Expr right)
extends Record
implements Expr

Expression for nullish coalescence operator that evaluates to the right side expression if the left side expression evaluates to null.

Constructor Details

NullishCoalescence

public NullishCoalescence(Expr left,
 Token operator,
 Expr right)

Creates an instance of a NullishCoalescence record class.

Parameters:

left - the value for the left record component

operator - the value for the operator record component

right - the value for the right record component

Method Details

accept

public <R> @Nullable R accept(Expr.Visitor<R> visitor)

Description copied from interface: Expr

Evaluate this expression via the desired Expr.Visitor

Specified by:

accept in interface Expr

Type Parameters:

R - the return type

Parameters:

visitor - the Expr.Visitor to evaluate this expression

Returns:

the evaluated value

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.

left

public Expr left()

Returns the value of the left record component.

Returns:

the value of the left record component

operator

public Token operator()

Returns the value of the operator record component.

Returns:

the value of the operator record component

right

public Expr right()

Returns the value of the right record component.

Returns:

the value of the right record component
