Class ImmutableSubGraph.Builder<T>

java.lang.Object

de.flapdoodle.graph.ImmutableSubGraph.Builder<T>

Enclosing class:

ImmutableSubGraph<T>

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

Builds instances of type ImmutableSubGraph. 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
ImmutableSubGraph<T>	build() Builds a new ImmutableSubGraph.
ImmutableSubGraph.Builder<T>	connections(Map<? extends T,? extends T> entries) Sets or replaces all mappings from the specified map as entries for the connections map.
ImmutableSubGraph.Builder<T>	from(GraphAsDot.SubGraph<T> instance) Fill a builder with attribute values from the provided SubGraph instance.
ImmutableSubGraph.Builder<T>	putAllConnections(Map<? extends T,? extends T> entries) Put all mappings from the specified map as entries to connections map.
ImmutableSubGraph.Builder<T>	putConnections(Map.Entry<? extends T,? extends T> entry) Put one entry to the connections map.
ImmutableSubGraph.Builder<T>	putConnections(T key, T value) Put one entry to the connections map.

Method Detail

from

public final ImmutableSubGraph.Builder<T> from(GraphAsDot.SubGraph<T> instance)

Fill a builder with attribute values from the provided SubGraph 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

putConnections

public final ImmutableSubGraph.Builder<T> putConnections(T key,
                                                         T value)

Put one entry to the connections map.

Parameters:

key - The key in the connections map

value - The associated value in the connections map

Returns:

this builder for use in a chained invocation

putConnections

public final ImmutableSubGraph.Builder<T> putConnections(Map.Entry<? extends T,? extends T> entry)

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

Parameters:

entry - The key and value entry

Returns:

this builder for use in a chained invocation

connections

public final ImmutableSubGraph.Builder<T> connections(Map<? extends T,? extends T> entries)

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

Parameters:

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

Returns:

this builder for use in a chained invocation

putAllConnections

public final ImmutableSubGraph.Builder<T> putAllConnections(Map<? extends T,? extends T> entries)

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

Parameters:

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

Returns:

this builder for use in a chained invocation

build

public ImmutableSubGraph<T> build()

Builds a new ImmutableSubGraph.

Returns:

An immutable instance of SubGraph

Throws:

IllegalStateException - if any required attributes are missing
