Detailed Description

template<typename T>
struct iArrayReadOnly< T >

Array interface template, read-only.

The functions provided allow to enumerate and read all elements of an array, but no modifications are permitted.

This template can't be used as-is in another interface; rather, it must be derived and specialized before it can be used. Example:

 struct csFoo { ... };
 struct iFooArray : public iArrayReadOnly<csFoo>
 {
   SCF_IARRAYREADONLY_INTERFACE(iFooArray);
 };

Standard implementations for this interface are scfArray, scfArrayWrap and scfArrayWrapConst.

Member Function Documentation

template<typename T>

virtual size_t iArrayReadOnly< T >::Find

(

T const &

which

)

const [pure virtual]

Find an element in array.

Returns:

csArrayItemNotFound if not found, else the item index.

Warning:

Performs a slow linear search.

template<typename T>

virtual T const& iArrayReadOnly< T >::Get

(

size_t

n

)

const [pure virtual]

Get an element (const).

Implemented in scfArrayWrapConst< iGradientShades, csArray< csGradientShade > >.

Referenced by csLightProperties::csLightProperties().

template<typename T>

virtual void iArrayReadOnly< T >::GetAll

(

T *

dest

)

const [pure virtual]

Copy all elements to dest.

dest should be large enough to take all elements contained in the array.

template<typename T>

virtual size_t iArrayReadOnly< T >::GetIndex

(

const T *

which

)

const [pure virtual]

Given a pointer to an element in the array this function will return the index.

Note that this function does not check if the returned index is actually valid. The caller of this function is responsible for testing if the returned index is within the bounds of the array.

template<typename T>

virtual size_t iArrayReadOnly< T >::GetSize

(

)

const [pure virtual]

Return the number of elements in the array.

Implemented in scfArrayWrapConst< iGradientShades, csArray< csGradientShade > >.

Referenced by csGetShaderVariableFromStack(), and csLightProperties::csLightProperties().

template<typename T>

virtual bool iArrayReadOnly< T >::IsEmpty

(

)

const [pure virtual]

Return true if the array is empty.

Remarks:

Rigidly equivalent to return GetSize() == 0, but more idiomatic.

Implemented in scfArrayWrapConst< iGradientShades, csArray< csGradientShade > >.

template<typename T>

virtual T const& iArrayReadOnly< T >::Top

(

)

const [pure virtual]

Return the top element but do not remove it (const).

Implemented in scfArrayWrapConst< iGradientShades, csArray< csGradientShade > >.
