C++ (Cpp) CScriptArray::Resize Examples

Example #1

File: scriptstdstring_utils.cpp Project: AnotherFoxGuy/ror-server

BEGIN_AS_NAMESPACE

// This function takes an input string and splits it into parts by looking
// for a specified delimiter. Example:
//
// string str = "A|B||D";
// array<string>@ array = str.split("|");
//
// The resulting array has the following elements:
//
// {"A", "B", "", "D"}
//
// AngelScript signature:
// array<string>@ string::split(const string &in delim) const
static CScriptArray *StringSplit(const string &delim, const string &str)
{
	// Obtain a pointer to the engine
	asIScriptContext *ctx = asGetActiveContext();
	asIScriptEngine *engine = ctx->GetEngine();

	// TODO: This should only be done once
	// TODO: This assumes that CScriptArray was already registered
	asIObjectType *arrayType = engine->GetObjectTypeByDecl("array<string>");

	// Create the array object
	CScriptArray *array = CScriptArray::Create(arrayType);

	// Find the existence of the delimiter in the input string
	int pos = 0, prev = 0, count = 0;
	while( (pos = (int)str.find(delim, prev)) != (int)string::npos )

	// Add the remaining part
	array->Resize(array->GetSize()+1);
