Methods

virtual
const std::type_info&
type() const

Implementation must return the type information (typeid) for the stored content.

virtual
void
convert(Int8& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(Int16& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(Int32& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(Int64& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(UInt8& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(UInt16& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(UInt32& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(UInt64& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(bool& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(float& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(double& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(char& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
void
convert(std::string& val) const

Throws BadCastException.

Must be overriden in a type specialization in order to suport the conversion.

virtual
VarHolder*
clone(Placeholder<VarHolder>* pHolder = 0) const

Implementation must implement this function to deep-copy the VarHolder.

If small object optimization is enabled (i.e. if POCO_NO_SOO is not defined), VarHolder will be instantiated in-place if it’s size is smaller than POCO_SMALL_OBJECT_SIZE.

virtual
bool
isArray() const

Returns true.

virtual
bool
isStruct() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.

virtual
bool
isInteger() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.

virtual
bool
isSigned() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.

virtual
bool
isNumeric() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.

virtual
bool
isBoolean() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.

virtual
bool
isString() const

Returns false.

Must be properly overriden in a type specialization in order to suport the diagnostic.
