Protheus :: Advpl :: Resolvendo a Limitação da ClassMethArr() com __ClsArr()

Regazzo estava manipulando a Classe dbTree e perguntou-me como fazer para “recolher” todos os “Nodes”, respondi: “Não Sei”. Deixe-me Pesquisar.

Usando ClassMethArr() para obter os Métodos da Classe dbTree percebi, pela descrição, que nenhum dos métodos listados iria resolver o seu problema.

Então, usei __ClsArr() para obter a Lista das Classes passiveis de uso em ADVPL e deparei-me com a TTREE. Presumi que TTREE era a Classe Base e, que dbTree, provavelmente, era derivada dela.

O problema com ClassMethArr() é que ela só lista os Métodos Específicos da Classe cujo objeto é passado como parâmetro. Os Métodos Herdados não são Listados.

Para isso temos que descobrir qual a Classe Base para, a partir daí, tentar descobrir o Método que irá atender à nossa necessidade. Neste caso, “recolher” todos os “Nodes” do Tree. O Método, em questão, é o PTCOLLAPSE().

Os Métodos da Classe TTree estão Listados abaixo:

TTree:Methods -> ARRAY (17) [...] TTree:Methods[1] -> ARRAY (2) [...] TTree:Methods[1][1] -> C (11) [BEGINUPDATE] TTree:Methods[1][2] -> ARRAY (0) [...] TTree:Methods[2] -> ARRAY (2) [...] TTree:Methods[2][1] -> C (9) [ENDUPDATE] TTree:Methods[2][2] -> ARRAY (0) [...] TTree:Methods[3] -> ARRAY (2) [...] TTree:Methods[3][1] -> C (3) [NEW] TTree:Methods[3][2] -> ARRAY (0) [...] TTree:Methods[4] -> ARRAY (2) [...] TTree:Methods[4][1] -> C (15) [PTADDARRAYNODES] TTree:Methods[4][2] -> ARRAY (0) [...] TTree:Methods[5] -> ARRAY (2) [...] TTree:Methods[5][1] -> C (10) [PTADDNODES] TTree:Methods[5][2] -> ARRAY (0) [...] TTree:Methods[6] -> ARRAY (2) [...] TTree:Methods[6][1] -> C (11) [PTCHANGEBMP] TTree:Methods[6][2] -> ARRAY (0) [...] TTree:Methods[7] -> ARRAY (2) [...] TTree:Methods[7][1] -> C (14) [PTCHANGEPROMPT] TTree:Methods[7][2] -> ARRAY (0) [...] TTree:Methods[8] -> ARRAY (2) [...] TTree:Methods[8][1] -> C (10) [PTCOLLAPSE] TTree:Methods[8][2] -> ARRAY (0) [...] TTree:Methods[9] -> ARRAY (2) [...] TTree:Methods[9][1] -> C (19) [PTDELETECURRENTNODE] TTree:Methods[9][2] -> ARRAY (0) [...] TTree:Methods[10] -> ARRAY (2) [...] TTree:Methods[10][1] -> C (10) [PTGETNIVEL] TTree:Methods[10][2] -> ARRAY (0) [...] TTree:Methods[11] -> ARRAY (2) [...] TTree:Methods[11][1] -> C (14) [PTGETNODECOUNT] TTree:Methods[11][2] -> ARRAY (0) [...] TTree:Methods[12] -> ARRAY (2) [...] TTree:Methods[12][1] -> C (11) [PTGETPROMPT] TTree:Methods[12][2] -> ARRAY (0) [...] TTree:Methods[13] -> ARRAY (2) [...] TTree:Methods[13][1] -> C (12) [PTGOTOTONODE] TTree:Methods[13][2] -> ARRAY (0) [...] TTree:Methods[14] -> ARRAY (2) [...] TTree:Methods[14][1] -> C (7) [PTRESET] TTree:Methods[14][2] -> ARRAY (0) [...] TTree:Methods[15] -> ARRAY (2) [...] TTree:Methods[15][1] -> C (11) [PTSENDNODES] TTree:Methods[15][2] -> ARRAY (0) [...] TTree:Methods[16] -> ARRAY (2) [...] TTree:Methods[16][1] -> C (10) [PTSENDTREE] TTree:Methods[16][2] -> ARRAY (0) [...] TTree:Methods[17] -> ARRAY (2) [...] TTree:Methods[17][1] -> C (9) [SETSCROLL] TTree:Methods[17][2] -> ARRAY (0) [...]
