LANGUAGE ÖÑ ´ÅÖÙØ¸ ³ÑÖÙØ³µ ØÖ×ÓÐ ´ÅÖÙØ¸ ÊÓÒ¸ ½¼¸ ¾µ Ö× ℄ ÓÖ ÊÙ× ½ ØÓ ¼ Ý ½ ÐØÓÒÖÐ ´ÊÓÒ¸ ÊÓÒÐØÓÒ¸ ÊÙ×µ ÖÒØÖ ´ÊÓÒÐØÓÒ¸ Ö¸ ÊÓÛ¸ ÓÐÙÑÒµ Ö×ÊÙ×¹½℄ Ö ÒÓÖ Please note that first the variable Ö× has to be initialized in order to avoid a runtime error. In the example Ö× is initialized with the empty tuple (℄). Instead of Ò×ÖØ the operator ××Ò with tuple concatenation Ö× Ö×¸Ö℄ could be used, because the element is appended at the back of the tuple. More examples can be found in the program ××ÒºÚ. 3.5.3 Basic Tuple Operations A basic tuple operation may be selecting one or more values, combining tuples (concatenation) or reading the number of elements. Ø¸Ø℄ Ø Ø℄ Ø℄ concatenation of tuples number of elements selection of an element selectionof(apartof)atuple Table 3.7: Basic operations on tuples The concatenation accepts one or more variables or constants as input. They are all listed between the brackets, separated by commas. The result again is a tuple. Ø ½¸Ø ¾ ℄ is the concatenation of tuple Ø ½ and Ø ¾ .Example: ¸³ÌÜØ³℄¸º℄℄ ¸³ÌÜØ³¸º℄ So even the following holds: Ø℄℄ Ø℄ Ø. Ø returns the number of elements of a tuple. The indices of elements range from zero to the number of elements minus one (i.e., Ø¹½). Therefore, the selection index has to be within this range. 2 ÌÙÔÐ Î½¸Î¾¸Î¿¸Î℄ ÓÖ ¼ ØÓ ÌÙÔÐ¹½ Ý ½ ÛÖØ×ØÖÒ ´ÐÀÒÐ¸ÌÙÔÐ℄·³Ò³µ ÒÓÖ 2 Please note that the index of objects (e.g., ×ÐØ ÓØ) ranges from 1 to the number of elements. <strong>HDevelop</strong> / 2000-11-16
3.5. EXPRESSIONS FOR INPUT CONTROL PARAMETERS 67 There are no direct operations on parameter position for the handling of iconic variables. This means that single iconic objects cannot be directly selected using [] and their number cannot be directly determined using []. For this purpose, however, HALCON operators are offered which carry out the equivalent tasks. In table 3.8 you can see tuple operations that work on control data and their counterparts that work on iconic data. In the table the symbol Ø represents a control tuple, and the symbols Ô and Õ represent iconic tuples. Further examples can be found in the program ØÙÔÐºÚ. control iconic ℄ ÑÔØÝÓ ´µ Ø ÓÙÒØÓ ´Ô¸ ÒÙÑµ Ø½¸Ø¾℄ ÓÒØÓ ´Ô½¸ Ô¾¸ Õµ Ø℄ ×ÐØÓ´Ô¸ Õ¸ ·½¸ ½µ Ø℄ ÓÔÝÓ´Ô¸ Õ¸ ·½¸ ¹·½µ Table 3.8: Equivalent tuple operations for control and iconic data 3.5.4 Tuple Creation The simplest way to create a tuple, as mentioned in section 3.2, is the use of constants together with the ××Ò operator: ××Ò´℄¸ÑÔØÝØÙÔÐµ ××Ò´½½¸ÓÒÒØÖµ ××Ò´½½¸¼º½℄¸ØÛÓÒÙÑÖ×µ This code is displayed as ÑÔØÝØÙÔÐ ℄ ÓÒÒØÖ ½½ ØÛÓÒÙÑÖ× ½½¸¼º½℄ This is useful for constant tuples with a fixed (small) length. More general tuples can be created by successive application of the concatenation or the Ò×ÖØ function together with variables, expressions or constants. If we want to generate a tuple of length 100, where each element has the value 4711, it might be done like this: ××Ò´℄¸ØÙÔÐµ ÓÖ ½ ØÓ ½¼¼ Ý ½ ××Ò´ØÙÔÐ¸½½℄¸ØÙÔÐµ ÒÓÖ which is transformed to ØÙÔÐ ℄ ÓÖ ½ ØÓ ½¼¼ Ý ½ ØÙÔÐ ØÙÔÐ¸½½℄ ÒÓÖ HALCON 6.0
