Detailed Description

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.

SymbolEntry * ScopeGhidraNamespace::addMapInternal	(	Symbol *	sym,
		uint4	exfl,
		const Address &	addr,
		int4	off,
		int4	sz,
		const RangeList &	uselim
	)

protectedvirtual

Create a new SymbolEntry for a Symbol given a memory range.

The SymbolEntry is specified in terms of a memory range and usepoint

Parameters

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)

Returns: the newly created SymbolEntry

Reimplemented from ScopeInternal.

	)		const

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.

Parameters

nm	is the given name to test
op2	is the terminating ancestor scope (or null)
