Here it is:
```
# Hash(K,V) class support providers
class CrystalHashSyntheticProvider:
def __init__(self, valobj, internal_dict):
self.valobj = valobj
self.extract_entries()
def has_children(self):
return True

size = self.valobj.GetChildMemberWithName("size").unsigned
return size
def get_child_index(self, name):
name = name.lstrip('[').rstrip(']')
if name == "size":
return len(self._entries) + 1 if self._entries else 1
try:
idx = next((index for index, obj in enumerate(self._entries) if
getattr(self._entries, "key") == name), -1)
return idx
except:
return -1
def get_child_at_index(self, index):
if index > len(self.entries):
return None
if index == len(self.entries):
return self.valobj.GetChildMemberWithName("size")
entry = self.entries[index]
key = entry.GetChildMemberWithName("key").GetSummary()
value = entry.GetChildMemberWithName("value").deref
return value.CreateChildAtOffset("[%s]" % key, 0, value.type)
# return entry.CreateChildAtOffset("[%d]" % index, 0, entry.type)
def extract_entries(self):
if self.valobj.type.is_pointer:
self.valobj = self.valobj.Dereference()
self.size = 0 if self.valobj.GetChildMemberWithName("size").value is
None else self.valobj.GetChildMemberWithName("size").unsigned
self.entries = []
for index in range(self.size):
try:
valuePath = "entries[%d]" % index
value = self.valobj.EvaluateExpression(valuePath)
if value.type.is_pointer:
value = value.deref
self.entries.append(value)
except Exception as e:
print('Got exception %s' % (str(e)))

print ("Created %d entries." % len(self.entries))
