Class SIRHelper

java.lang.Object
  at.dms.kjc.sir.SIROperator
      at.dms.kjc.sir.SIRStream
          at.dms.kjc.sir.SIRHelper

All Implemented Interfaces:: DeepCloneable, Finalizable, SIRCodeUnit, Serializable, Cloneable

This class represents a set of helper methods available to all filters.

Field Summary

Fields inherited from class at.dms.kjc.sir.SIRStream
`fields, ident, init, methods, work`

Constructor Summary
`SIRHelper(boolean _native)`

Method Summary
`Object`	`accept(AttributeStreamVisitor v)`
`CType`	`getInputType()` Returns the input type of this.
`CType`	`getOutputType()` Returns the output type of this.
`int`	`getPopForSchedule(HashMap[] counts)` Same as getPushForSchedule, but with pop instead of push.
`int`	`getPushForSchedule(HashMap[] counts)` Returns the number of items pushed out of this stream in one execution of the steady-state, given the steady-state execution counts specified by (as in SIRScheduler.) Requires that contains a firing for each filter that contained in the hierarchy of this (does not depend on splitters / joiners.) The intent of this method is that can be calculated once for a stream graph, then the splitjoins & pipelines of the graph can be refactored, and one can still call this to get the push count of new constructs without re-invoking the scheduler.
`LIRStreamType`	`getStreamType()` Returns the type of this stream.
`boolean`	`isNative()`
`boolean`	`needsInit()` Returns whether or not this class needs a call to an init function to be generated.
`boolean`	`needsWork()` Returns whether or not this class needs a call to a work function to be generated.
`void`	`setInit(JMethodDeclaration newInit)` sets the init function
`void`	`setInitWithoutReplacement(JMethodDeclaration newInit)` sets the init function WITHOUT eliminating the old one in the methods array.
`void`	`setWork(JMethodDeclaration newWork)` Sets the work function.
