Method Detail

add

void add(MergedReftable.RefQueueEntry t)
  throws java.io.IOException

Throws:

java.io.IOException

next

public boolean next()
             throws java.io.IOException

Description copied from class: RefCursor

Check if another reference is available.

Specified by:

next in class RefCursor

Returns:

true if there is another result.

Throws:

java.io.IOException - references cannot be read.

seekPastPrefix

public void seekPastPrefix(java.lang.String prefixName)
                    throws java.io.IOException

Description copied from class: RefCursor

Seeks forward to the first ref record lexicographically beyond prefixName that doesn't start with prefixName. If there are no more results, skipping some refs won't add new results. E.g if we create a RefCursor that returns only results with a specific prefix, skipping that prefix won't give results that are not part of the original prefix.

Specified by:

seekPastPrefix in class RefCursor

Parameters:

prefixName - prefix that should be skipped. All previous refs before it will be skipped.

Throws:

java.io.IOException - references cannot be read.

poll

private MergedReftable.RefQueueEntry poll()

skipShadowedRefs

private void skipShadowedRefs(java.lang.String name)
                       throws java.io.IOException

Throws:

java.io.IOException

getRef

public Ref getRef()

Description copied from class: RefCursor

Get reference at the current position.

Specified by:

getRef in class RefCursor

Returns:

reference at the current position.

close

public void close()

Description copied from class: RefCursor

Specified by:

close in interface java.lang.AutoCloseable

Specified by:
