rt.aaA

Implementation of associative arrays.
Authors:
Martin Nowak
immutable int _aaVersion;
AA version for debuggers, bump whenever changing the layout
struct AA;
Opaque AA wrapper
pure nothrow @nogc size_t _aaLen(in AA aa);
Determine number of entries in associative array.
void* _aaGetY(AA* aa, const TypeInfo_AssociativeArray ti, in size_t valsz, in void* pkey);
Lookup *pkey in aa. Called only from implementation of (aa[key]) expressions when value is mutable.
Parameters:
AA* aa associative array opaque pointer
TypeInfo_AssociativeArray ti TypeInfo for the associative array
size_t valsz ignored
void* pkey pointer to the key value
Returns:
if key was in the aa, a mutable pointer to the existing value. If key was not in the aa, a mutable pointer to newly inserted value which is set to all zeros
inout(void)* _aaGetRvalueX(inout AA aa, in TypeInfo keyti, in size_t valsz, in void* pkey);
Lookup *pkey in aa. Called only from implementation of (aa[key]) expressions when value is not mutable.
Parameters:
AA aa associative array opaque pointer
TypeInfo keyti TypeInfo for the key
size_t valsz ignored
void* pkey pointer to the key value
Returns:
pointer to value if present, null otherwise
inout(void)* _aaInX(inout AA aa, in TypeInfo keyti, in void* pkey);
Lookup *pkey in aa. Called only from implementation of (key in aa) expressions.
Parameters:
AA aa associative array opaque pointer
TypeInfo keyti TypeInfo for the key
void* pkey pointer to the key value
Returns:
pointer to value if present, null otherwise
bool _aaDelX(AA aa, in TypeInfo keyti, in void* pkey);
Delete entry in AA, return true if it was present
pure nothrow void _aaClear(AA aa);
Remove all elements from AA.
pure nothrow void* _aaRehash(AA* paa, in TypeInfo keyti);
Rehash AA
pure nothrow inout(void[]) _aaValues(inout AA aa, in size_t keysz, in size_t valsz, const TypeInfo tiValueArray);
Return a GC allocated array of all values
pure nothrow inout(void[]) _aaKeys(inout AA aa, in size_t keysz, const TypeInfo tiKeyArray);
Return a GC allocated array of all keys
int _aaApply(AA aa, in size_t keysz, dg_t dg);
foreach opApply over all values
int _aaApply2(AA aa, in size_t keysz, dg2_t dg);
foreach opApply over all key/value pairs
Impl* _d_assocarrayliteralTX(const TypeInfo_AssociativeArray ti, void[] keys, void[] vals);
Construct an associative array of type ti from keys and value
int _aaEqual(in TypeInfo tiRaw, in AA aa1, in AA aa2);
compares 2 AAs for equality
nothrow hash_t _aaGetHash(in AA* aa, in TypeInfo tiRaw);
compute a hash
struct Range;
aaRange implements a ForwardRange
