Constructor Detail

### ProfilingPngSerializer

    public ProfilingPngSerializer()

Method Detail

### setOutputStream

    public void setOutputStream(OutputStream outputStream)

  Specified by:
    `setOutputStream` in interface `Finisher`

### getContentType

    public String getContentType()

  Specified by:
    `getContentType` in interface `Finisher`

### finish

    public void finish()

  Writes the image data to the output stream.

  Specified by:
    `finish` in interface `PipelineComponent`

### setConfiguration

    public void setConfiguration(Map<String,? extends Object> configuration)

  Pass component specific configuration parameters to the pipeline component in a generic way. This is useful in environments that automatically assemble pipelines with their components and can't use the components constructors or setters.

  Specified by:
    `setConfiguration` in interface `PipelineComponent`
  Parameters:
    `configuration` - The `Map` of configuration parameters.

### execute

    public void execute()

  Specified by:
    `execute` in interface `Starter`

### setProfilingDataHolder

    public void setProfilingDataHolder(ProfilingDataHolder dataHolder)

### setup

    public void setup(Map<String,Object> parameters)

  The shared object map for this pipeline run.

  Specified by:
    `setup` in interface `PipelineComponent`
  Parameters:
    `parameters` - A `Map` of parameters that are available to all `PipelineComponent`s. This is a modifiable map that can be changed by this pipeline component.

### constructCacheKey

    public CacheKey constructCacheKey()

  Specified by:
    `constructCacheKey` in interface `CachingPipelineComponent`
