Detailed Description

Analyze a symbol, classify it as to whether it just a scalar, a CHARACTER scalar, an array entity, a combination thereof, and whether the LEN, shape, and lbounds are constant or not.

Member Typedef Documentation

VT

using Fortran::lower::BoxAnalyzer::VT

Initial value:

 std::variant<None, ScalarSym, ScalarStaticChar, ScalarDynamicChar,
                          StaticArray, DynamicArray, StaticArrayStaticChar,
                          StaticArrayDynamicChar, DynamicArrayStaticChar,
                          DynamicArrayDynamicChar>

Member Function Documentation

isStaticArray()

bool Fortran::lower::BoxAnalyzer::isStaticArray ( ) const

inline

Returns true iff this is an array with constant extents and lbounds. This returns true for arrays of CHARACTER, even if the LEN is not a constant.
