Method Detail

flush

public void flush()

insert

public final boolean insert(int fs)

compare

public int compare(int fs1,
          int fs2)

Description copied from interface: IntComparator

Compare two ints.

Specified by:

compare in interface IntComparator

Overrides:

compare in class FSLeafIndexImpl

Parameters:

fs1 - first int.

fs2 - second int.

Returns:

-1 if i < j; 1 if i > j; 0 if i == j.

pointerIterator

public ComparableIntPointerIterator pointerIterator(IntComparator comp,
                                           int[] detectIllegalIndexUpdates,
                                           int typeCode)

Specified by:

pointerIterator in class FSLeafIndexImpl

refIterator

protected IntPointerIterator refIterator()

Specified by:

refIterator in class FSLeafIndexImpl

See Also:

FSLeafIndexImpl.refIterator()

ll_iterator

public LowLevelIterator ll_iterator()

Description copied from interface: LowLevelIndex

Get a low-level, FS reference iterator.

Returns:

An iterator for this index.

refIterator

protected IntPointerIterator refIterator(int fsCode)

Specified by:

refIterator in class FSLeafIndexImpl

See Also:

FSLeafIndexImpl.refIterator(int)

contains

public boolean contains(FeatureStructure fs)

Description copied from interface: FSIndex

Check if the index contains an element equal to the given feature structure according to the ordering of the index. Note that this is in general not the same as feature structure identity.

Parameters:

fs - The FS we're looking for.

Returns:

true if the index contains such an element.

See Also:

FSIndex.contains(FeatureStructure)

find

public FeatureStructure find(FeatureStructure fs)

Description copied from interface: FSIndex

Find an entry in the index equal to the given feature structure according to the ordering of the index. Note that this is in general not the same as feature structure identity.

Parameters:

fs - The FS we're looking for.

Returns:

A FS equal to fs, or null if no such FS exists.

See Also:

FSIterator.moveTo(FeatureStructure)

size

public int size()

Description copied from interface: FSIndex

Return the number of feature structures in this index.

Returns:

The number of FSs in this index.

See Also:

FSIndex.size()

deleteFS

public void deleteFS(FeatureStructure fs)

Description copied from class: FSLeafIndexImpl

Method deleteFS.

Specified by:

deleteFS in class FSLeafIndexImpl

See Also:

FSLeafIndexImpl.deleteFS(org.apache.uima.cas.FeatureStructure)

remove

public void remove(int fsRef)

hashCode

public int hashCode()

Overrides:

hashCode in class FSLeafIndexImpl
