const std::type_info &  ti 
)
inherited

Release an element retrieved from the getter.

Parameters
pThe element to release.
tiThe type of p.

Call this when you are done with the element returned by nextUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

◆ releaseObject() [1/2]

virtual void D3PD::CollectionGetterTool< IParticleLinks >::releaseObject ( const IParticleLinks p)
virtualinherited

Release an object retrieved from the getter.

Parameters
pThe object to release.

Call this when you are done with the object returned by get(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

◆ releaseObject() [2/2]

template<class T >
void D3PD::IObjGetterTool::releaseObject ( const T *  p)
inherited

Type-safe wrapper for releaseObjectUntyped.

Parameters
pThe object to release.

Call this when you are done with the object returned by get(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

This is implemented in terms of releaseObjectTypeinfo().

◆ releaseObjectTypeinfo()

void D3PD::IObjGetterTool::releaseObjectTypeinfo ( const void *  p,
const std::type_info &  ti 
)
inherited

Release an object retrieved from the getter.

Parameters
pThe object to release.
tiThe type of p.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

◆ releaseObjectUntyped() [1/2]

virtual void D3PD::IObjGetterTool::releaseObjectUntyped ( const void *  p)
virtualinherited

Release an object retrieved from the getter.

Parameters
pThe object to release.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

◆ releaseObjectUntyped() [2/2]

virtual void D3PD::CollectionGetterTool< IParticleLinks >::releaseObjectUntyped ( const void *  p)
virtualinherited

Release an object retrieved from the getter.

Parameters
pThe object to release.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

◆ reset()

virtual StatusCode D3PD::CollectionGetterTool< IParticleLinks >::reset ( bool  allowMissing = false)
virtualinherited

Reset the iteration to the start of the collection.

Parameters
allowMissingIf true, then we should not generate errors if the requested object is missing.

Return failure if the container cannot be retrieved.

◆ sizeHint()

virtual size_t D3PD::CollectionGetterTool< IParticleLinks >::sizeHint ( bool  allowMissing = false)
virtualinherited

Return an estimate of the number of elements in the iteration.

Parameters
allowMissingIf true, then we should not generate errors if the requested object is missing.

This can be used to pre-allocate memory. (It's possible that this isn't known in advance of iterating over the entire collection, for example if a selection is being applied, so this is only a hint.)

◆ typeinfo() [1/2]

virtual const std::type_info& D3PD::SGCollectionGetterTool< IParticleLinks >::typeinfo
virtualinherited

Return the type of object retrieved by this tool.

Reimplemented from D3PD::CollectionGetterTool< IParticleLinks >.

Implements D3PD::IObjGetterTool.

Reimplemented in D3PD::SGCollectionGetterTool< CONT >, D3PD::SGTileDigitsGetterTool, D3PD::SGTileHitGetterTool, D3PD::SGTileModuleBitsGetterTool, and D3PD::SGTileRawChannelGetterTool.
