Detailed Description

This module creates a load context for IDM generic loaders (ListLoadType, LayerArrayLoadType, GridArrayLoadType) that supports consistent package side access. It also determines in scope parameters for the generic dynamic loaders and all structarray based static loads.

allocate_arrays()

subroutine loadcontextmodule::allocate_arrays

(

class(loadcontexttype)

this

)

call this routine after input parameters have been allocated, e.g. after load_params() with create has been called for array based loaders or after all mem_create_vector() calls have been made for list based load.

sum_named_bounds()

		character(len=*), intent(in)	mempath,
		integer(i4b), intent(inout)	total
	)

Loops over each name in named_bound and accumulates its value from mempath into total. Variables not present in mempath are silently skipped.
