Member Function Documentation

bool FlatStoreItr::operator==

(

const DTN::BundlePointerRepr &

b

)

[virtual]

Equality operator.

Parameters:

b

Another iterator

Returns:

whether the two iterators refer to the same bundle

Implements DTN::BundlePointerRepr.

Definition at line 224 of file FlatStore.cc.

References DTN::BundlePointerRepr::bundle().

DTN::BundlePointerRepr * FlatStoreItr::next

(

)

[virtual]

Get the next iterator for the store.

A new pointer is created, with the caller taking responsibility for the memory management.

Returns:

the store's next iterator, or NULL if there is none

Implements DTN::BundlePointerRepr.

Definition at line 230 of file FlatStore.cc.

References FlatStore::end(), FlatStoreItr(), and FlatStore::upper_bound().

DTN::BundlePointerRepr * FlatStoreItr::clone

(

)

[virtual]

Copy an iterator.

A new pointer is created, with the caller taking responsibility for the memory management.

Returns:

a copy of this iterator

Implements DTN::BundlePointerRepr.

Definition at line 241 of file FlatStore.cc.

References FlatStoreItr().

DTN::Bundle * FlatStoreItr::bundle

(

)

const [virtual]

Retrieve the actual stored DTN::Bundle.

Note that if you have not tested the DTN::BundlePointer that owns this DTN::BundlePointerRepr for validity, the returned pointer might not be valid.

Let me repeat that: You must test the encompassing DTN::BundlePointer for validity or you are very likely to get a segmentation fault at some point.

Returns:

a pointer to the stored DTN::Bundle

Implements DTN::BundlePointerRepr.
