Detailed Description

template<class T>
class PScalarArray< T >

This template class maps the PAbstractArray to a specific element type.

The functions in this class primarily do all the appropriate casting of types.

Note that if templates are not used the PSCALAR_ARRAY macro will simulate the template instantiation.

The following classes are instantiated automatically for the basic scalar types:

PBYTEArray
PShortArray
PWORDArray
PIntArray
PUnsignedArray
PLongArray
PDWORDArray

Constructor & Destructor Documentation

template<class T>

PScalarArray< T >::PScalarArray ( PINDEX initialSize = 0 )

inline

Construct a new dynamic array of elements of the specified type.

The array is initialised to all zero bytes. Note that this may not be logically equivalent to the zero value for the type, though this would be very rare.

Parameters

initialSize Initial number of elements in the array.

template<class T>

PScalarArray< T >::PScalarArray	(	T const *	buffer,
		PINDEX	length,
		PBoolean	dynamic = `true`
	)

inline

Construct a new dynamic array of elements of the specified type.

Parameters

buffer	Pointer to an array of the elements of type T.
length	Number of elements pointed to by `buffer`.
dynamic	Buffer is copied and dynamically allocated.
