Method Detail

makeFeature

protected abstract PointFeature makeFeature(int recnum,
                                            StructureData sdata)
                                     throws java.io.IOException

Throws:

java.io.IOException

hasNext

public boolean hasNext()
                throws java.io.IOException

Description copied from interface: PointFeatureIterator

Check if another PointFeature is available

Specified by:

hasNext in interface PointFeatureIterator

Returns:

true if another PointFeature is available

Throws:

java.io.IOException - on i/o error

next

public PointFeature next()
                  throws java.io.IOException

Description copied from interface: PointFeatureIterator

Returns the next PointFeature. You must call hasNext() before calling next(), even if you know it will return true.

Specified by:

next in interface PointFeatureIterator

Returns:

the next PointFeature

Throws:

java.io.IOException - on i/o error

setBufferSize

public void setBufferSize(int bytes)

Description copied from interface: PointFeatureIterator

Hint to use this much memory in buffering the iteration. No guarentee that it will be used by the implementation.

Specified by:

setBufferSize in interface PointFeatureIterator

Parameters:

bytes - amount of memory in bytes
