net.bmahe.genetics4j.gpu.spec.fitness.kernelcontext.ImmutableKernelExecutionContext.Builder

Direct Known Subclasses:

KernelExecutionContext.Builder

Enclosing class:

ImmutableKernelExecutionContext

public static class ImmutableKernelExecutionContext.Builder
extends Object

Builds instances of type ImmutableKernelExecutionContext. 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 ImmutableKernelExecutionContext instances.

 new KernelExecutionContext.Builder()
    .globalWorkSize(long) // required globalWorkSize
    .workGroupSize(long[]) // optional workGroupSize
    .build();
 

Method Details

from

public final KernelExecutionContext.Builder from(KernelExecutionContext instance)

Fill a builder with attribute values from the provided KernelExecutionContext 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

globalWorkSize

public final KernelExecutionContext.Builder globalWorkSize(long... globalWorkSize)

Initializes the value for the globalWorkSize attribute.

Parameters:

globalWorkSize - The elements for globalWorkSize

Returns:

this builder for use in a chained invocation

workGroupSize

public final KernelExecutionContext.Builder workGroupSize(long[] workGroupSize)

Initializes the optional value workGroupSize to workGroupSize.

Parameters:

workGroupSize - The value for workGroupSize

Returns:

this builder for chained invocation

workGroupSize

public final KernelExecutionContext.Builder workGroupSize(Optional<? extends long[]> workGroupSize)

Initializes the optional value workGroupSize to workGroupSize.

Parameters:

workGroupSize - The value for workGroupSize

Returns:

this builder for use in a chained invocation

build

public ImmutableKernelExecutionContext build()

Builds a new ImmutableKernelExecutionContext.

Returns:

An immutable instance of KernelExecutionContext

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
