Method Details

ifClauses

public List<Expression.IfClause> ifClauses()

Specified by:

ifClauses in class Expression.IfThen

Returns:

The value of the ifClauses attribute

elseClause

public Expression elseClause()

Specified by:

elseClause in class Expression.IfThen

Returns:

The value of the elseClause attribute

withIfClauses

public final ImmutableExpression.IfThen withIfClauses(Expression.IfClause... elements)

Copy the current immutable object with elements that replace the content of ifClauses.

Parameters:

elements - The elements to set

Returns:

A modified copy of this object

withIfClauses

public final ImmutableExpression.IfThen withIfClauses(Iterable<? extends Expression.IfClause> elements)

Copy the current immutable object with elements that replace the content of ifClauses. A shallow reference equality check is used to prevent copying of the same value by returning this.

Parameters:

elements - An iterable of ifClauses elements to set

Returns:

A modified copy or this if not changed

withElseClause

public final ImmutableExpression.IfThen withElseClause(Expression value)

Copy the current immutable object by setting a value for the elseClause attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.

Parameters:

value - A new value for elseClause

Returns:

A modified copy or the this object

equals

public boolean equals(Object another)

This instance is equal to all instances of IfThen that have equal attribute values.

Overrides:

equals in class Object

Returns:

true if this is equal to another instance

hashCode

public int hashCode()

Computes a hash code from attributes: ifClauses, elseClause.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value IfThen with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

public static ImmutableExpression.IfThen copyOf(Expression.IfThen instance)

Creates an immutable copy of a Expression.IfThen value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.

Parameters:

instance - The instance to copy

Returns:

A copied immutable IfThen instance

builder

public static ImmutableExpression.IfThen.Builder builder()

Creates a builder for IfThen.

 ImmutableExpression.IfThen.builder()
    .addIfClauses|addAllIfClauses(io.substrait.expression.Expression.IfClause) // ifClauses elements
    .elseClause(io.substrait.expression.Expression) // required elseClause
    .build();
 

Returns:

A new IfThen builder
