Class ImmutableSignature.Builder<T>

java.lang.Object

de.flapdoodle.eval.core.evaluables.ImmutableSignature.Builder<T>

Enclosing class:

ImmutableSignature<T>

public static final class ImmutableSignature.Builder<T>
extends Object

Builds instances of type ImmutableSignature. 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

Modifier and Type	Method and Description
ImmutableSignature.Builder<T>	addAllParameters(Iterable<? extends Parameter<?>> elements) Adds elements to parameters list.
ImmutableSignature.Builder<T>	addParameters(Parameter<?>... elements) Adds elements to parameters list.
ImmutableSignature.Builder<T>	addParameters(Parameter<?> element) Adds one element to parameters list.
ImmutableSignature<T>	build() Builds a new ImmutableSignature.
ImmutableSignature.Builder<T>	from(Signature<T> instance) Fill a builder with attribute values from the provided Signature instance.
ImmutableSignature.Builder<T>	isVarArg(boolean isVarArg) Initializes the value for the isVarArg attribute.

Method Detail

from

public final ImmutableSignature.Builder<T> from(Signature<T> instance)

Fill a builder with attribute values from the provided Signature instance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values. Collection elements and entries will be added, not replaced.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

addParameters

public final ImmutableSignature.Builder<T> addParameters(Parameter<?> element)

Adds one element to parameters list.

Parameters:

element - A parameters element

Returns:

this builder for use in a chained invocation

addParameters

@SafeVarargs
public final ImmutableSignature.Builder<T> addParameters(Parameter<?>... elements)

Adds elements to parameters list.

Parameters:

elements - An array of parameters elements

Returns:

this builder for use in a chained invocation

parameters

public final ImmutableSignature.Builder<T> parameters(Iterable<? extends Parameter<?>> elements)

Sets or replaces all elements for parameters list.

Parameters:

elements - An iterable of parameters elements

Returns:

this builder for use in a chained invocation

addAllParameters

public final ImmutableSignature.Builder<T> addAllParameters(Iterable<? extends Parameter<?>> elements)

Adds elements to parameters list.

Parameters:

elements - An iterable of parameters elements

Returns:

this builder for use in a chained invocation

isVarArg

public final ImmutableSignature.Builder<T> isVarArg(boolean isVarArg)

Initializes the value for the isVarArg attribute.

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

Parameters:

isVarArg - The value for isVarArg

Returns:

this builder for use in a chained invocation

build

public ImmutableSignature<T> build()

Builds a new ImmutableSignature.

Returns:

An immutable instance of Signature

Throws:

IllegalStateException - if any required attributes are missing
