Constructor Detail

AlgorithmInstanceBuilder

public AlgorithmInstanceBuilder()

Construct a new algorithm instance builder.

AlgorithmInstanceBuilder

public AlgorithmInstanceBuilder(String name)

Construct a new algorithm instance builder with a name.

Parameters:

name - The algorithm name.

Method Detail

setName

public AlgorithmInstanceBuilder setName(String n)

Set the algorithm name.

Parameters:

n - The name for this algorithm instance.

Returns:

The command for chaining.

getName

public String getName()

Get the algorithm name.

Returns:

The algorithm name.

setAttribute

public AlgorithmInstanceBuilder setAttribute(@Nonnull
                                             String attr,
                                             @Nonnull
                                             Object value)

Set an attribute for this algorithm instance. Used for distinguishing similar instances in an algorithm family.

Parameters:

attr - The attribute name.

value - The attribute value.

Returns:

The command for chaining.

getAttributes

public Map<String,Object> getAttributes()

Get the attributes of this algorithm instance.

Returns:

A map of user-defined attributes for this algorithm instance, excluding attributes inherited from the parent.

getAllAttributes

public Map<String,Object> getAllAttributes()

Get all attributes of this algorithm instance.

Returns:

A map of all attributes in this algorithm instance.

getConfig

public LenskitConfiguration getConfig()

Get the LensKit configuration.

Returns:

The LensKit configuration.

setConfig

public AlgorithmInstanceBuilder setConfig(LenskitConfiguration cfg)

Set the LensKit configuration to use.

Parameters:

cfg - The configuration to use. This will override any non-inherited configuration.

Returns:

The builder (for chaining).

getConfigurations

public List<LenskitConfiguration> getConfigurations()

Get the list of configurations that comprise this instance.

Returns:

The list of configurations comprising this instance.

extend

public AlgorithmInstanceBuilder extend()

Create a new builder that inherits from this builder. Changes to the returned builder will not affect this builder, but subsequent changes to this builder will affect the inherited builder.

Returns:

The duplicate instance builder.
