Method Details

createStartFunction

@Nonnull
FunctionName createStartFunction(Iterator<FunctionName> writeLaterClinit)
                          throws IOException

Create a start function for the static class constructors

Parameters:

writeLaterClinit - iterator of all needed static constructors

Returns:

the synthetic function name

Throws:

IOException - if any I/O error occur

scan

private StaticCodeBuilder.ScanState scan(FunctionName name,
 LinkedHashMap<String, FunctionName> constructors)

Scan for for references to other classes

Parameters:

name - the name of the static constructor (class initializer)

constructors - all static constructors which have references or was not scanned

Returns:

the reference state

patch

private void patch(StaticCodeBuilder.ScanState scan,
 LinkedHashMap<String, StaticCodeBuilder.ScanState> scans)

Patch static constructor (class initializer)

Parameters:

scan - the current scan

scans - a list with all static constructors which was not called
