Remove unnecessary null pointer checks

[elfring]

An extra null pointer check is not needed in functions like the following.

• SegmentationGL
• stdVectorClear

[banterle]

you are perfectly right. However, not all compilers for all platforms support that.

Did you measure a huge bottleneck from those IFs?

However, not all compilers for all platforms support that.

Would you like to point any tools out which are not compliant to the C++ standard according to the linked implementation detail?

💭 Would you become interested to use a development tool like “clang-tidy” for corresponding source code adjustments?

Probably old compilers.

This aspect will be considered in the future. Probably when moving to smart pointers.

• How far would you like to go back in history?
• Would you dare to restrict development support on C++ standard compliant tools?

Probably when moving to smart pointers.

💭 I would find it helpful if redundant pointer checks could be deleted before occasionally.

Not now.

[elfring]

🔮 Do you need any configuration checks for incompliant tools (by the software build system)?

[banterle]

No, thank you.

[elfring]

🔮 In which time range do you plan to work more with smart pointers?

[banterle]

Why?

💭 Smart pointers can also help to get rid of redundant pointer checks, can't they?
