Class ImmutableLoop.Builder<V,E>

java.lang.Object

de.flapdoodle.graph.ImmutableLoop.Builder<V,E>

Enclosing class:

ImmutableLoop<V,E>

public static final class ImmutableLoop.Builder<V,E>
extends Object

Builds instances of type ImmutableLoop. 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
ImmutableLoop.Builder<V,E>	addAllEdges(Iterable<? extends Edge<V,E>> elements) Adds elements to edges set.
ImmutableLoop.Builder<V,E>	addEdges(Edge<V,E>... elements) Adds elements to edges set.
ImmutableLoop.Builder<V,E>	addEdges(Edge<V,E> element) Adds one element to edges set.
ImmutableLoop<V,E>	build() Builds a new ImmutableLoop.
ImmutableLoop.Builder<V,E>	edges(Iterable<? extends Edge<V,E>> elements) Sets or replaces all elements for edges set.
ImmutableLoop.Builder<V,E>	from(Loop<V,E> instance) Fill a builder with attribute values from the provided Loop instance.

Method Detail

from

public final ImmutableLoop.Builder<V,E> from(Loop<V,E> instance)

Fill a builder with attribute values from the provided Loop 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

addEdges

public final ImmutableLoop.Builder<V,E> addEdges(Edge<V,E> element)

Adds one element to edges set.

Parameters:

element - A edges element

Returns:

this builder for use in a chained invocation

addEdges

@SafeVarargs
public final ImmutableLoop.Builder<V,E> addEdges(Edge<V,E>... elements)

Adds elements to edges set.

Parameters:

elements - An array of edges elements

Returns:

this builder for use in a chained invocation

edges

public final ImmutableLoop.Builder<V,E> edges(Iterable<? extends Edge<V,E>> elements)

Sets or replaces all elements for edges set.

Parameters:

elements - An iterable of edges elements

Returns:

this builder for use in a chained invocation

addAllEdges

public final ImmutableLoop.Builder<V,E> addAllEdges(Iterable<? extends Edge<V,E>> elements)

Adds elements to edges set.

Parameters:

elements - An iterable of edges elements

Returns:

this builder for use in a chained invocation

build

public ImmutableLoop<V,E> build()

Builds a new ImmutableLoop.

Returns:

An immutable instance of Loop

Throws:

IllegalStateException - if any required attributes are missing
