詳細描述

This datapoint type encodes a string of QKnxChar . The encoding of the string is specified in QKnxCharStringASCII and QKnxCharString88591 .

This is a fixed size datapoint type with the length of 14 bytes.

The range for the string size is from 0 to 14 .

`[protected]` QKnxCharString:: QKnxCharString ( int subType , const char * string , int size )

Creates a fixed size datapoint type with the subtype subType , storing the string string with the length size .

QKnxCharString:: QKnxCharString (const char * string , int size = -1)

Creates a fixed size datapoint type storing the string string with the length size .

QKnxCharString:: QKnxCharString ( QLatin1String string )

Creates a fixed size datapoint type storing the string string .

QKnxCharString:: QKnxCharString ()

Creates a fixed size datapoint type with the value set to 0 .

`[override virtual]` bool QKnxCharString:: isValid () const

重實現： QKnxDatapointType::isValid () const.

bool QKnxCharString:: setString ( QLatin1String string )

Sets the string stored in the datapoint type to string .

返迴 true if the value was set; otherwise returns false .

bool QKnxCharString:: setString (const char * string , int size = -1)

Sets the string stored in the datapoint type to string with the length size .

若 size is -1 , the full string 被使用。

If the value is outside the allowed range, returns false and does not set the string.

QLatin1String QKnxCharString:: string () const

Returns the string stored in the datapoint type.
