Class ImmutableConnection.Builder

java.lang.Object

net.bmahe.genetics4j.neat.ImmutableConnection.Builder

Direct Known Subclasses:

Connection.Builder

Enclosing class:

ImmutableConnection

public static class ImmutableConnection.Builder
extends Object

Builds instances of type ImmutableConnection. 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.

Constructor Details

Builder

public Builder()

Creates a builder for ImmutableConnection instances.

 new Connection.Builder()
    .fromNodeIndex(int) // required fromNodeIndex
    .toNodeIndex(int) // required toNodeIndex
    .weight(float) // required weight
    .isEnabled(boolean) // required isEnabled
    .innovation(int) // required innovation
    .build();
 

Method Details

from

public final Connection.Builder from(Connection instance)

Fill a builder with attribute values from the provided Connection 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

fromNodeIndex

public final Connection.Builder fromNodeIndex(int fromNodeIndex)

Initializes the value for the fromNodeIndex attribute.

Parameters:

fromNodeIndex - The value for fromNodeIndex

Returns:

this builder for use in a chained invocation

toNodeIndex

public final Connection.Builder toNodeIndex(int toNodeIndex)

Initializes the value for the toNodeIndex attribute.

Parameters:

toNodeIndex - The value for toNodeIndex

Returns:

this builder for use in a chained invocation

weight

public final Connection.Builder weight(float weight)

Initializes the value for the weight attribute.

Parameters:

weight - The value for weight

Returns:

this builder for use in a chained invocation

isEnabled

public final Connection.Builder isEnabled(boolean isEnabled)

Initializes the value for the isEnabled attribute.

Parameters:

isEnabled - The value for isEnabled

Returns:

this builder for use in a chained invocation

innovation

public final Connection.Builder innovation(int innovation)

Initializes the value for the innovation attribute.

Parameters:

innovation - The value for innovation

Returns:

this builder for use in a chained invocation

build

public ImmutableConnection build()

Builds a new ImmutableConnection.

Returns:

An immutable instance of Connection

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
