Member Function Documentation

Get()

virtual const char* Get ( ) const

pure virtual

Gets the pointer to the current associated nullterminated-string.

Returns

The pointer to the null-terminated string.

Remarks

Check the pointer, because it depends on the implementation of IString!

Implemented in cStringRedirect, cStringLengthProxy, adtf_string< T >, and cQtIStringImpl.

Referenced by property_value< T >::FromString().

GetLength()

virtual size_t GetLength ( ) const

pure virtual

Gets the current size of the strng.

Usually this is in Bytes (null-termination is not included!)

Returns

The size of the string.

Return values

If	not valid return InvalidPos!

Implemented in cStringRedirect, cStringLengthProxy, adtf_string< T >, and cQtIStringImpl.

Set()

virtual tResult Set ( const char *  strValue )

pure virtual

Sets the given null-terminated string to the implementation.

Parameters

strValue

[in] The null-terminated string to set.

Return values

ERR_NOERROR	The value is set successfully
ERR_MEMORY	The value can not be set. Too long. No truncating provided.

Implemented in cStringRedirect, adtf_string< T >, cQtIStringImpl, and cStringLengthProxy.
