构造器详细资料

SequenceIterator

public SequenceIterator(int start,
                        int size,
                        ArrayStructureBak abb)

方法详细资料

hasNext

public boolean hasNext()
                throws java.io.IOException

从接口复制的说明: StructureDataIterator

See if theres more StructureData in the iteration. You must always call this before calling next().

指定者:

hasNext 在接口中 StructureDataIterator

返回:

true if more records are available

抛出:

java.io.IOException - on read error

next

public StructureData next()
                   throws java.io.IOException

从接口复制的说明: StructureDataIterator

Get the next StructureData in the iteration.

指定者:

next 在接口中 StructureDataIterator

返回:

next StructureData record.

抛出:

java.io.IOException - on read error

setBufferSize

public void setBufferSize(int bytes)

从接口复制的说明: StructureDataIterator

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

指定者:

setBufferSize 在接口中 StructureDataIterator

参数:

bytes - amount of memory in bytes

reset

public StructureDataIterator reset()

从接口复制的说明: StructureDataIterator

Start the iteration over again.

指定者:

reset 在接口中 StructureDataIterator

返回:

a new or reset iterator.

getCurrentRecno

public int getCurrentRecno()

指定者:

getCurrentRecno 在接口中 StructureDataIterator

finish

public void finish()

从接口复制的说明: StructureDataIterator

Make sure that the iterator is complete, and recover resources. Best to put in a try/finally block like:

 try {
   while (iter.hasNext())
    process(iter.next());
  } finally {
    iter.finish();
  }
   

指定者:

finish 在接口中 StructureDataIterator
