Macro Definition Documentation

◆ EBGEOMETRY_EXPECT

#define EBGEOMETRY_EXPECT ( cond ) ((void)(cond))

Runtime precondition assertion for EBGeometry.

When EBGEOMETRY_ENABLE_ASSERTIONS is defined (e.g. via -DEBGEOMETRY_ENABLE_ASSERTIONS on the compiler command line, in CXXFLAGS for GNU Make, or via CMake's target_compile_definitions), this macro evaluates cond and, if it is false, prints a diagnostic message to stderr and calls std::abort().

When EBGEOMETRY_ENABLE_ASSERTIONS is not defined the macro still evaluates the condition (to suppress "unused variable" warnings from variables that appear only inside assertions) but the result is discarded at zero runtime cost.

Enabling assertions: # CMake

target_compile_definitions(MyTarget PRIVATE EBGEOMETRY_ENABLE_ASSERTIONS)

# GNU Make

CXXFLAGS += -DEBGEOMETRY_ENABLE_ASSERTIONS

# Command line

g++ -DEBGEOMETRY_ENABLE_ASSERTIONS ...

Parameters

cond	Boolean-convertible expression to test.
