FilteringChangingIndexedRowIterator

public FilteringChangingIndexedRowIterator(MutableIndexedRowIterator iterator,
                                           RowDecorator decorator,

Method Detail

reset

public void reset()
           throws AxionException

Description copied from interface: RowIterator

Re-initialize this RowIterator to its initial state (positioned just before the first Rowin the list).

Specified by:

reset in interface RowIterator

Overrides:

reset in class AbstractFilteringRowIterator

Throws:

AxionException

setIndexKey

public void setIndexKey(Object value)
                 throws AxionException

Specified by:

setIndexKey in interface MutableIndexedRowIterator

Throws:

AxionException

removeIndexKey

public void removeIndexKey()
                    throws AxionException

Specified by:

removeIndexKey in interface MutableIndexedRowIterator

Throws:

AxionException

indexSet

public boolean indexSet()

Specified by:

indexSet in interface MutableIndexedRowIterator

isEmpty

public boolean isEmpty()

Description copied from interface: RowIterator

Returns true if there are no rows to report with this iterator.

Specified by:

isEmpty in interface RowIterator

Overrides:

isEmpty in class DelegatingRowIterator

hasNext

public boolean hasNext()

Description copied from interface: RowIterator

Returns true if I have more Rows when traversing the list in the forward direction. (In other words, returns true iff RowIterator.next()would return a Rowrather than throwing an exception.)

Specified by:

hasNext in interface RowIterator

Overrides:

hasNext in class AbstractFilteringRowIterator

hasPrevious

public boolean hasPrevious()

Description copied from interface: RowIterator

Returns true if I have more Rows when traversing the list in the reverse direction. (In other words, returns true iff RowIterator.previous()would return a Rowrather than throwing an exception.)

Specified by:

hasPrevious in interface RowIterator

Overrides:

hasPrevious in class AbstractFilteringRowIterator

getShortName

public String getShortName()

Overrides:

getShortName in class FilteringRowIterator
