SAValueRead::asCursor

SACommand *asCursor( ) const;
throw (SAException);

operator SACommand *( ) const;
throw (SAException);

asCursor method returns the value of current object (usually SAField or SAParam object) as a pointer to SACommand object.

operator SACommand *() substitute asCursor method to provide quick access for object's value.

Remarks

If the value of current object is NULL, asCursor method returns NULL. Use SAValueRead::isNull method to make sure if the value is NULL or not.

If the value's type of current object is cursor (SA_dtCursor), asCursor method returns a pointer to SACommand object.

If the value's type of current object is any data type except SA_dtCursor, the result is undefined and debug version asserts.

Use SAValueRead::DataType method to get the value's type of SAValueRead object.
