public class ArrayBlockReader
extends BlockReader

This class implements the simplest possible BlockReader. I wrote it because I needed something to test Entity with. It is called ArrayBlockReader, because the constructor is passed an array of entries and an array of subblocks, and that's how they're stored. N.B.: Locations and contexts are not implemented (and presumably, won't be, because this is only intended for testing). All other methods are overridden and do exactly what they should according to the specification of BlockReader. If you try to read beyond the end of the Entry/Subblock list, you get an Array:IndexOutOfBounds exception.

Constructor Summary

ArrayBlockReader(java.lang.String h, java.lang.String p, java.lang.String[][] e, BlockReader[] sub)
          Construct an ArrayBlockReader from strings and string arrays.

Method Summary

BlockReaderLocation getBlockLocation()
          Similar to getEntryLocation

BlockReaderContext getContext(BlockReaderLocation loc)
          Converts a Location into a fully-qualified Context object.

BlockReaderLocation getEntryLocation()
          Returns a BlockReaderLocation object describing the current Entry location.

java.lang.String getHeader()
          Returns the header of this block.

BlockReader getNextBlock()
          Returns the next subblock, which is an instance of BlockReader.

java.lang.String[] getNextEntry()
          Returns the next Entry, as a string array.

java.lang.String getParameter()
          Returns the parameter of this block.

boolean hasMoreBlocks()
          Returns TRUE if this block has more Blocks after the one that was last returned

boolean hasMoreEntries()
          Returns TRUE if this block has more Entries after the one that was last returned

BlockReader peekNextBlock()
          This method acts as getNextBlock() but does not advance position

java.lang.String[] peekNextEntry()
          This method acts as getNextEntry() but does not advance position

void seekFirstBlock()
          Resets the subblock position to the beginning, so that the next call to getNextBlock() will return the first subblock (unless there are no subblocks, in which case an exception is thrown, of course.

void seekFirstEntry()
          Moves the "entry pointer" back to the first Entry, so that the next call to getNextEntry() will return the first one in the block

java.lang.String toString()
          This method lists the contents of the BlockReader.
