## Class R2BlurParameters.Builder

- java.lang.Object
- - com.io7m.r2.filters.R2BlurParameters.Builder

- Enclosing class:
    R2BlurParameters

      public static final class R2BlurParameters.Builder
      extends Object

  Builds instances of type `R2BlurParameters`. 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.

    - #### from

          public final R2BlurParameters.Builder from(R2BlurParametersType instance)

      Fill a builder with attribute values from the provided `R2BlurParametersType` 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

    - #### setBlurSize

          public final R2BlurParameters.Builder setBlurSize(float blurSize)

      Initializes the value for the `blurSize` attribute.

      If not set, this attribute will have a default value as returned by the initializer of `blurSize`.

      Parameters:
        `blurSize` - The value for blurSize
      Returns:
        `this` builder for use in a chained invocation

    - #### setBlurScale

          public final R2BlurParameters.Builder setBlurScale(float blurScale)

      Initializes the value for the `blurScale` attribute.

      If not set, this attribute will have a default value as returned by the initializer of `blurScale`.

      Parameters:
        `blurScale` - The value for blurScale
      Returns:
        `this` builder for use in a chained invocation

    - #### setBlurPasses

          public final R2BlurParameters.Builder setBlurPasses(int blurPasses)

      Initializes the value for the `blurPasses` attribute.

      If not set, this attribute will have a default value as returned by the initializer of `blurPasses`.

      Parameters:
        `blurPasses` - The value for blurPasses
      Returns:
        `this` builder for use in a chained invocation

    - #### setBlurScaleFilter

          public final R2BlurParameters.Builder setBlurScaleFilter(com.io7m.jcanephora.core.JCGLFramebufferBlitFilter blurScaleFilter)

      Initializes the value for the `blurScaleFilter` attribute.

      If not set, this attribute will have a default value as returned by the initializer of `blurScaleFilter`.

      Parameters:
        `blurScaleFilter` - The value for blurScaleFilter
      Returns:
        `this` builder for use in a chained invocation

    - #### build

          public R2BlurParameters build()

      Builds a new `R2BlurParameters`.
      Returns:
        An immutable instance of R2BlurParameters
