Class ImmutableExpression.Builder

java.lang.Object

de.flapdoodle.eval.core.ImmutableExpression.Builder

Enclosing class:

ImmutableExpression

public static final class ImmutableExpression.Builder
extends Object

Builds instances of type ImmutableExpression. 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 Summary

Method Detail

from

public final ImmutableExpression.Builder from(Expression instance)

Fill a builder with attribute values from the provided Expression instance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

mathContext

public final ImmutableExpression.Builder mathContext(MathContext mathContext)

Initializes the value for the mathContext attribute.

Parameters:

mathContext - The value for mathContext

Returns:

this builder for use in a chained invocation

zoneId

public final ImmutableExpression.Builder zoneId(ZoneId zoneId)

Initializes the value for the zoneId attribute.

Parameters:

zoneId - The value for zoneId

Returns:

this builder for use in a chained invocation

source

public final ImmutableExpression.Builder source(String source)

Initializes the value for the source attribute.

Parameters:

source - The value for source

Returns:

this builder for use in a chained invocation

root

public final ImmutableExpression.Builder root(Node root)

Initializes the value for the root attribute.

Parameters:

root - The value for root

Returns:

this builder for use in a chained invocation

build

public ImmutableExpression build()

Builds a new ImmutableExpression.

Returns:

An immutable instance of Expression
