Examples of findFunction()

com.caucho.quercus.env.QuercusClass.findFunction()
Finds the matching function.
org.apache.poi.ss.formula.udf.IndexedUDFFinder.findFunction()
org.apache.poi.xssf.model.IndexedUDFFinder.findFunction()
org.erlide.engine.model.erlang.IErlModule.findFunction()
org.teiid.query.function.FunctionLibrary.findFunction()
Find a function descriptor given a name and the types of the arguments. This method matches based on case-insensitive function name and an exact match of the number and types of parameter arguments. @param name Name of the function to resolve @param types Array of classes representing the types @return Descriptor if found, null if not found
