-// This file defines an API to "push" an evaluated array constructor value
-// "from" into some storage "to" of an array constructor. It can be seen as a
-// form of std::vector::push_back() implementation for Fortran array
-// constructors. In the APIs and ArrayConstructorVector struct above:
-//
-// - "to" is a ranked-1 descriptor whose declared type is already set to the
-// array constructor derived type. It may be already allocated, even before the
-// first call to this API, or it may be unallocated. "to" extent is increased
-// every time a "from" is pushed past its current extent. At this end of the
-// API calls, its extent is the extent of the array constructor. If "to" is
-// unallocated and its extent is not null, it is assumed this is the final
array
-// constructor extent value, and the first allocation already "reserves"
storage
-// space accordingly to avoid reallocations.
-// - "from" is a scalar or array descriptor for the evaluated array
-// constructor value that must be copied into the storage of "to" at
-// "nextValuePosition".
-// - "useValueLengthParameters" must be set to true if the array constructor
-// has length parameters and no type spec. If it is true and "to" is
-// unallocated, "to" will take the length parameters of "from". If it is true
-// and "to" is an allocated character array constructor, it will be checked
-// that "from" length matches the one from "to". When it is false, the
-// character length must already be set in "to" before the first call to this
-// API and "from" character lengths are allowed to mismatch from "to".
-// - "nextValuePosition" is the zero based sequence position of "from" in the
-// array constructor. It is updated after this call by the number of "from"
-// elements. It should be set to zero by the caller of this API before the
first
-// call.
-// - "actualAllocationSize" is the current allocation size of "to" storage. It
-// may be bigger than "to" extent for reallocation optimization purposes, but
-// should never be smaller, unless this is the first call and "to" is
-// unallocated. It is updated by the runtime after each successful allocation
or
-// reallocation. It should be set to "to" extent if "to" is allocated before
the
-// first call of this API, and can be left undefined otherwise.
-//
-// Note that this API can be used with "to" being a variable (that can be
-// discontiguous). This can be done when the variable is the left hand side of
-// an assignment from an array constructor as long as:
-// - none of the ac-value overlaps with the variable,
-// - this is an intrinsic assignment that is not a whole allocatable
-// assignment, *and* for a type that has no components requiring user defined
-// assignments,
-// - the variable is properly finalized before using this API if its need to,
-// - "useValueLengthParameters" should be set to false in this case, even if
-// the array constructor has no type-spec, since the variable may have a
-// different character length than the array constructor values.

+// This file defines an API to "push" an evaluated array constructor value
+// "from" into some storage "to" of an array constructor. It can be seen as a
+// form of std::vector::push_back() implementation for Fortran array
+// constructors. In the APIs and ArrayConstructorVector struct above:
+//
+// - "to" is a ranked-1 descriptor whose declared type is already set to the
+// array constructor derived type. It may be already allocated, even before the
+// first call to this API, or it may be unallocated. "to" extent is increased
+// every time a "from" is pushed past its current extent. At this end of the
+// API calls, its extent is the extent of the array constructor. If "to" is
+// unallocated and its extent is not null, it is assumed this is the final
array
+// constructor extent value, and the first allocation already "reserves"
storage
+// space accordingly to avoid reallocations.
+// - "from" is a scalar or array descriptor for the evaluated array
+// constructor value that must be copied into the storage of "to" at
+// "nextValuePosition".
+// - "useValueLengthParameters" must be set to true if the array constructor
+// has length parameters and no type spec. If it is true and "to" is
+// unallocated, "to" will take the length parameters of "from". If it is true
+// and "to" is an allocated character array constructor, it will be checked
+// that "from" length matches the one from "to". When it is false, the
+// character length must already be set in "to" before the first call to this
+// API and "from" character lengths are allowed to mismatch from "to".
+// - "nextValuePosition" is the zero based sequence position of "from" in the
+// array constructor. It is updated after this call by the number of "from"
+// elements. It should be set to zero by the caller of this API before the
first
+// call.
+// - "actualAllocationSize" is the current allocation size of "to" storage. It
+// may be bigger than "to" extent for reallocation optimization purposes, but
+// should never be smaller, unless this is the first call and "to" is
+// unallocated. It is updated by the runtime after each successful allocation
or
+// reallocation. It should be set to "to" extent if "to" is allocated before
the
+// first call of this API, and can be left undefined otherwise.
+//
+// Note that this API can be used with "to" being a variable (that can be
+// discontiguous). This can be done when the variable is the left hand side of
+// an assignment from an array constructor as long as:
+// - none of the ac-value overlaps with the variable,
+// - this is an intrinsic assignment that is not a whole allocatable
+// assignment, *and* for a type that has no components requiring user defined
+// assignments,
+// - the variable is properly finalized before using this API if its need to,
+// - "useValueLengthParameters" should be set to false in this case, even if
+// the array constructor has no type-spec, since the variable may have a
+// different character length than the array constructor values.
