Method Detail

isPipeline

public PipelineIter isPipeline()

Description copied from interface: Iterator

Checks if the iterator points to a Pipeline. If so, returns a Pipeline iterator that points to the same object. If not, returns null.

Specified by:

isPipeline in interface Iterator

Overrides:

isPipeline in class SIRIterator

Returns:

iterator to a Pipeline or null if self doesn't point to a Pipeline

getStream

public SIRStream getStream()

Return the stream pointed to by this.

Specified by:

getStream in class SIRIterator

getNumChildren

public int getNumChildren()

Description copied from interface: PipelineIter

Returns the number of children this pipeline has.

Specified by:

getNumChildren in interface PipelineIter

Returns:

number of children

getChild

public Iterator getChild(int n)

Description copied from interface: PipelineIter

Returns an Iterator to a particular child of this pipeline.

Specified by:

getChild in interface PipelineIter

Returns:

a child

get

public SIRIterator get(int n)

The same as with a different signature.

accept

public void accept(StreamVisitor v)

Specified by:

accept in class SIRIterator

getUnspecializedIter

public Iterator getUnspecializedIter()

This function is needed by the scheduler, but isn't useful from the compiler.

Specified by:

getUnspecializedIter in interface PipelineIter

Returns:

an Iterator that points to the same object
