3.5.2 Evaluate Data Format
After the data is converted into a common data format based on the symbology, the
application determines the data format and processes according to data content.
if (data matches employee-badge format)
{
loginForm.employeeField.text = decode.data;
loginForm.pinField.text = "";
gui.showForm(loginForm);
return null;
}
else if data matches part-number format
{
stockForm.partField.text = decode.data;
gui.showForm(stockForm);
return null;
}
else if (data matches shelf-number format)
{
stockForm.shelfField.text = decode.data;
gui.showForm(stockForm);
return null;
}
The previous statements from the example demonstrate the processing of data within the
decode handler. Based on the data format, the application program extracts data from the
decode and displays appropriate forms.
These examples execute a return null statement to consume the decode for the specified
data formats.
