Package io.substrait.expression

Class ImmutableExpression.MapLiteral.Builder

java.lang.Object

io.substrait.expression.ImmutableExpression.MapLiteral.Builder

Enclosing class:

ImmutableExpression.MapLiteral

public static final class ImmutableExpression.MapLiteral.Builder
extends Object

Builds instances of type MapLiteral. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

Method Details

from

public final ImmutableExpression.MapLiteral.Builder from(Expression.MapLiteral instance)

Fill a builder with attribute values from the provided io.substrait.expression.Expression.MapLiteral instance.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

from

public final ImmutableExpression.MapLiteral.Builder from(Expression.Literal instance)

Fill a builder with attribute values from the provided io.substrait.expression.Expression.Literal instance.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

nullable

public final ImmutableExpression.MapLiteral.Builder nullable(boolean nullable)

Initializes the value for the nullable attribute.

If not set, this attribute will have a default value as returned by the initializer of nullable.

Parameters:

nullable - The value for nullable

Returns:

this builder for use in a chained invocation

putValues

public final ImmutableExpression.MapLiteral.Builder putValues(Expression.Literal key,
 Expression.Literal value)

Put one entry to the values map.

Parameters:

key - The key in the values map

value - The associated value in the values map

Returns:

this builder for use in a chained invocation

putValues

public final ImmutableExpression.MapLiteral.Builder putValues(Map.Entry<? extends Expression.Literal,? extends Expression.Literal> entry)

Put one entry to the values map. Nulls are not permitted

Parameters:

entry - The key and value entry

Returns:

this builder for use in a chained invocation

values

public final ImmutableExpression.MapLiteral.Builder values(Map<? extends Expression.Literal,? extends Expression.Literal> entries)

Sets or replaces all mappings from the specified map as entries for the values map. Nulls are not permitted

Parameters:

entries - The entries that will be added to the values map

Returns:

this builder for use in a chained invocation

putAllValues

public final ImmutableExpression.MapLiteral.Builder putAllValues(Map<? extends Expression.Literal,? extends Expression.Literal> entries)

Put all mappings from the specified map as entries to values map. Nulls are not permitted

Parameters:

entries - The entries that will be added to the values map

Returns:

this builder for use in a chained invocation

build

public ImmutableExpression.MapLiteral build()

Builds a new MapLiteral.

Returns:

An immutable instance of MapLiteral

Throws:

IllegalStateException - if any required attributes are missing
