BindRawPtr() [1/2]

void ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::BindRawPtr ( void * valuePtr )

inline

Bind the value to valuePtr.

Parameters

[in]

valuePtr

Pointer to bind the value to.

Warning

Use this function with care! Values may not always be valid for every entry during processing, for example when a field is not present in one of the chained processors or when during a join operation, no matching entry in the auxiliary processor can be found. Reading valuePtr as-is therefore comes with the risk of reading invalid data. After binding a pointer to an RNTupleProcessorOptionalPtr, we strongly recommend only accessing its data through this interface, to ensure that only valid data can be read.

Definition at line 99 of file RNTupleProcessor.hxx.

GetPtr() [2/2]

std::shared_ptr< void > ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::GetPtr ( ) const

inline

Get the pointer to the field value managed by the processor's entry.

Returns

A std::shared_ptr<void> if the field is valid in the current entry, or a nullptr otherwise.

Definition at line 184 of file RNTupleProcessor.hxx.

GetRawPtr() [1/2]

void * ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::GetRawPtr ( ) const

inline

Get a non-owning pointer to the field value managed by the processor's entry.

Returns

A T* if the field is valid in the current entry, or a nullptr otherwise.

Definition at line 113 of file RNTupleProcessor.hxx.

GetRawPtr() [2/2]

void * ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::GetRawPtr ( ) const

inline

Get a non-owning pointer to the field value managed by the processor's entry.

Returns

A void* if the field is valid in the current entry, or a nullptr otherwise.

Definition at line 198 of file RNTupleProcessor.hxx.

HasValue() [1/2]

bool ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::HasValue ( ) const

inline

Definition at line 93 of file RNTupleProcessor.hxx.

HasValue() [2/2]

bool ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::HasValue ( ) const

inline

Check if the pointer currently holds a valid value.

Definition at line 178 of file RNTupleProcessor.hxx.

operator*()

const void & ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::operator* ( ) const

inline

Get a reference to the field value managed by the processor's entry.

Throws an exception if the field is invalid in the processor's current entry.

Definition at line 131 of file RNTupleProcessor.hxx.

operator->()

const void * ROOT::Experimental::RNTupleProcessorOptionalPtr< void >::operator-> ( ) const

inline

Access the field value managed by the processor's entry.

Throws an exception if the field is invalid in the processor's current entry.
