Helper class to read attributes by type.

Methods

virtual const IAttributeList& getList () const = 0

Get associated attribute list.

Variant getVariant (StringID id) const

Get variant value.

int64 getInt64 (StringID id) const

Get integer value (64 bit).

int getInt (StringID id) const

Get integer value (32 bit).

bool getBool (StringID id) const

Get boolean value.

double getFloat (StringID id) const

Get floating-point value (double precision).

String getString (StringID id) const

Get string value (possibly converted).

MutableCString getCString (StringID id, TextEncoding encoding = Text::kASCII) const

Get C-string value (possibly converted).

IUnknown* getUnknown (StringID id) const

Get object value.

The attribute list maintains ownership.

IUnknownIterator* newUnknownIterator (StringID id) const

Create iterator for attribute queue, objects are of type IAttribute.

tresult getResult (StringID id) const

Get tresult value.

bool getInt64 (int64& value, StringID id) const

Get integer value (64 bit).
