StructureDataIterator (NetCDF-Java CDM Public API v5.6.0)

All Superinterfaces:

AutoCloseable, Closeable

All Known Implementing Classes:

ArrayStructure.ArrayStructureIterator, SequenceIterator, StructureDataIteratorLimited, StructureDataIteratorMediated
```
public interface StructureDataIterator
extends Closeable
```
An iterator over StructureData. Make sure that you call close(). Best to put in a try/finally block like:
```
 try {
   while (iter.hasNext())
     process(iter.next());
 } finally {
   iter.finish();
 }
 
```

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`close()`	Make sure that the iterator is complete, and recover resources.
`int`	`getCurrentRecno()`
`boolean`	`hasNext()`	See if theres more StructureData in the iteration.
`StructureData`	`next()`	Get the next StructureData in the iteration.
`StructureDataIterator`	`reset()`	Start the iteration over again.
`default void`	`setBufferSize(int bytes)`	Hint to use this much memory in buffering the iteration.

- Method Detail
  - hasNext
```
boolean hasNext()
         throws IOException
```
    See if theres more StructureData in the iteration. You must always call this before calling next().
    
    Returns:
    
    true if more records are available
    
    Throws:
    
    IOException - on read error
  - next
```
StructureData next()
            throws IOException
```
    Get the next StructureData in the iteration.
    
    Returns:
    
    next StructureData record.
    
    Throws:
    
    IOException - on read error
  - setBufferSize
```
default void setBufferSize(int bytes)
```
    Hint to use this much memory in buffering the iteration. No guarentee that it will be used by the implementation.
    
    Parameters:
    
    bytes - amount of memory in bytes
  - reset
```
StructureDataIterator reset()
```
    Start the iteration over again.
    
    Returns:
    
    a new or reset iterator.
  - getCurrentRecno
```
int getCurrentRecno()
```
  - close
```
default void close()
```
    Make sure that the iterator is complete, and recover resources. Best to put in a try/finally block like:
    try (StructureDataIterator iter = obj.getStructureDataIterator()) { while (iter.hasNext()) process(iter.next()); }
