Member Function Documentation

static void* xAOD::TDVCollectionFuncs::clear

(

void *

env

)

[inline, static]

Erase the container.

Parameters:

env

The proxy environment.

static Cont_t* xAOD::TDVCollectionFuncs::cont

(

void *

env

)

[inline, static]

Fetch the container from a proxy environment.

Parameters:

env

The proxy environment.

static void* xAOD::TDVCollectionFuncs::first

(

void *

env

)

[inline, static]

Return the first element of the container.

This resets the internal pointer to 0.

Parameters:

env

The proxy environment.

Returns:

A pointer to the first element, or 0 if the container is empty.

static void* xAOD::TDVCollectionFuncs::next

(

void *

env

)

[inline, static]

Return a following element of the container.

The internal pointer will be advanced by the value of e.idx (after which e.idx will be reset to 0). A pointer to the element referenced by this new index will be returned.

Parameters:

env

The proxy environment.

Returns:

A pointer to the following element, or 0 if we're past the end.

static void* xAOD::TDVCollectionFuncs::size

(

void *

env

)

[inline, static]

Return the size of the container.

Parameters:

env

The proxy environment.
