Method Details

iterator

public Iterator<Map<String,Serializable>> iterator()

Specified by:

iterator in interface Iterable<Map<String,Serializable>>

close

public void close()

Description copied from interface: IterableQueryResult

Closes the query result and releases the underlying resources held by the cursor.

This MUST be called when the query result is no more needed, otherwise underlying resources will be leaked. There is no auto-closing at the end of the iteration.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface IterableQueryResult

mustBeClosed

public boolean mustBeClosed()

Description copied from interface: IterableQueryResult

Indicates if the query result must be closed (because it holds resources).

Specified by:

mustBeClosed in interface IterableQueryResult

Returns:

true if the query result must be closed, false otherwise

size

public long size()

Description copied from interface: IterableQueryResult

Gets the total size of the query result.

Note that this may be costly, and that some backends may not be able to do this operation, in which case -1 will be returned.

Specified by:

size in interface IterableQueryResult

Returns:

the size, or -1 for an unknown size

pos

public long pos()

Description copied from interface: IterableQueryResult

Gets the current position in the iterator.

Positions start at 0.

Specified by:

pos in interface IterableQueryResult

Returns:

the position

skipTo

public void skipTo(long pos)

Description copied from interface: IterableQueryResult

Skips to a given position in the iterator.

Positions start at 0.

Specified by:

skipTo in interface IterableQueryResult

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Map<String,Serializable>>

next

public Map<String,Serializable> next()

Specified by:

next in interface Iterator<Map<String,Serializable>>

remove

public void remove()

Specified by:

remove in interface Iterator<Map<String,Serializable>>
