Constructor Detail

CodeStoreHelperSimple

public CodeStoreHelperSimple(FilterSliceNode node,
                             BackEndFactory backEndBits)

Constructor

Parameters:

node - A filter slice node to wrap code for.

backEndBits - The back end factory as a source of data and back end specific functions.

Method Detail

getInitStageMethod

public JMethodDeclaration getInitStageMethod()

Calculate and return the method that implements the init stage computation for this filter. It should be called only once in the generated code.

This does not include the call to the init function of the filter. That is done in RawComputeCodeStore#addInitFunctionCall.

Specified by:

getInitStageMethod in class CodeStoreHelper

Returns:

The method that implements the init stage for this filter.

getPrimePumpMethod

public JMethodDeclaration getPrimePumpMethod()

Specified by:

getPrimePumpMethod in class CodeStoreHelper

Returns:

The method to call for one execution of the filter in the prime pump stage.

getSteadyBlock

public JBlock getSteadyBlock()

Specified by:

getSteadyBlock in class CodeStoreHelper

Returns:

The block we should inline to execute the steady-state
