Member Function Documentation

Bind()

void ROOT::RNTupleProcessorValuePtr< void >::Bind ( std::shared_ptr< 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 RNTupleProcessorValuePtr, we strongly recommend only accessing its data through this interface, to ensure that only valid data can be read.

Definition at line 244 of file RNTupleProcessor.hxx.

BindRawPtr()

void ROOT::RNTupleProcessorValuePtr< void >::BindRawPtr ( void * valuePtr )

inlineprivate

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.

GetPtr()

std::shared_ptr< void > ROOT::RNTupleProcessorValuePtr< 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 224 of file RNTupleProcessor.hxx.

GetRawPtr()

void * ROOT::RNTupleProcessorValuePtr< void >::GetRawPtr ( ) const

inlineprivate

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 201 of file RNTupleProcessor.hxx.

HasValue()

bool ROOT::RNTupleProcessorValuePtr< void >::HasValue ( ) const

inline

Check if the pointer currently holds a valid value.

Definition at line 218 of file RNTupleProcessor.hxx.
