uint8 | uniqueId |

A global namespace Scope.
The only difference between this and a ScopeInternal is that this scope builds up its ownership range with the symbols that are placed in it. This allows Database::mapScope() to recover the namespace Scope for symbols that have been placed in it. Queries for namespace symbols that haven't been cached yet percolate up to the global scope, which must be a ScopeGhidra. This will query the Ghidra client on behalf of the namespace and register any new symbols with this Scope.

protectedvirtual |
Create a new SymbolEntry for a Symbol given a memory range.
The SymbolEntry is specified in terms of a memory range and usepoint
sym | is the given Symbol being mapped |
exfl | are any boolean Varnode properties specific to the memory range |
addr | is the starting address of the given memory range |
off | is the byte offset of the new SymbolEntry (relative to the whole Symbol) |
sz | is the number of bytes in the range |
uselim | is the given usepoint (which may be invalid) |
Reimplemented from ScopeInternal.

virtual |
Check if the given name is occurs within the given scope path.
Test for the presence of a symbol with the given name in either this scope or an ancestor scope up to but not including the given terminating scope. If the name is used true is returned.
nm | is the given name to test |
op2 | is the terminating ancestor scope (or null) |
