Detailed Description

template<typename ElementAccessType, typename ChildElementsType = ChildElements<ElementAccessType>>
class ddl::codec::DecoderElement< ElementAccessType, ChildElementsType >

A DecoderElement to get values.

Template Parameters

ElementAccessType

The element access concept type. (see concept templates DecoderElementAccess, CodecElementAccess)

Definition at line 938 of file codec_iterator.h.

Member Function Documentation

getAddress()

const void* getAddress ( ) const

inline

Get the address of the element.

Returns

const void*

Definition at line 1022 of file codec_iterator.h.

References FactoryElement< ElementAccessType, ChildElementsType >::getIndex().

getArrayElement()

self_type getArrayElement ( size_t  array_pos = 0 ) const

inline

Get the array element of the given array_pos.

Parameters

array_pos

The array pos of the element to retrieve

Returns

self_type

Definition at line 1043 of file codec_iterator.h.

References FactoryElement< ElementAccessType, ChildElementsType >::getIndex().

getChildElement()

self_type getChildElement ( const std::string &  name ) const

inline

Get the child element with the given name.

Parameters

name	Name of the child element.

Returns

self_type

Definition at line 1031 of file codec_iterator.h.

References FactoryElement< ElementAccessType, ChildElementsType >::getFullName().

getRawValue()

void getRawValue ( void *  value, size_t  value_size  ) const

inline

Get the as copy to the value buffer.

Parameters

value	The value buffer to copy to
value_size	The size of the value buffer (if 0 its unsafe usage without size check!, the size is only retrieved from the codec information)

Definition at line 1013 of file codec_iterator.h.

References FactoryElement< ElementAccessType, ChildElementsType >::getIndex().

getStringValue()

std::string getStringValue ( ) const

inline

Get the value as string.

Returns

value as string (the value is returned as enum element name in case of enum type)

Definition at line 1003 of file codec_iterator.h.

References FactoryElement< ElementAccessType, ChildElementsType >::getIndex().

getValue()

T getValue ( ) const

inline

Get the value as type T.

Template Parameters

T	Type of the value to return

Returns

value in type T (supported types: all int types, bool, float, double, std::string)

Remarks

for T = std::string the value is returned as element name in case of enum type
