Method Details

insertionIndex

public static int insertionIndex(int[] pcToSourceMap,
 int length,
 int pc)

This methods searches for an existing entry inside the pcToSourceMap table with a pc equals to @pc. If there is an existing entry it returns -1 (no insertion required). Otherwise it returns the index where the entry for the pc has to be inserted. This is based on the fact that the pcToSourceMap table is sorted according to the pc.

Parameters:

pcToSourceMap - the given pcToSourceMap array

length - the given length

pc - the given pc

Returns:

int

generateSyntheticBodyForConstructorAccess

public void generateSyntheticBodyForConstructorAccess(SyntheticMethodBinding accessBinding)

Parameters:

generateSyntheticBodyForEnumValueOf

public void generateSyntheticBodyForEnumValueOf(SyntheticMethodBinding methodBinding)

generateSyntheticBodyForDeserializeLambda

public void generateSyntheticBodyForDeserializeLambda(SyntheticMethodBinding methodBinding,
 SyntheticMethodBinding[] syntheticMethodBindings)

This is intended to match what javac generates. First there is a switch statement on the hashcode of the lambda method name - based on that an id is computed (0..N). An unrecognized hash gets the id -1. Then a second switch is on the id and each case here checks all the properties of the serialized lambda. If they all checkout OK an invokedynamic call to a bootstrap method targeting the altMetafactory. If any of the tests fail an IllegalArgumentException is thrown. This exception is not typically seen by the 'user', instead they seem to see a NPE when the lambda does not deserialize properly.

loadInt

Based on the supplied value add the most efficient load instruction to the code stream for that value. Note: Does not handle negative values.

pushPatternAccessTrapScope

public void pushPatternAccessTrapScope(BlockScope scope)

Stack the scope responsible for any pattern access exceptions not trapped by subscopes. Not all scopes bear responsibility: only method scopes (including clinit, init, lambdas) and try block scopes need to trap component pattern accessor exceptions and install handlers that throw a MatchException.

Parameters:

scope - some scope where the buck should stop for all pattern access exceptions underneath

patternAccessorsMayThrow

public boolean patternAccessorsMayThrow(BlockScope scope)

Should the reference context associated with the scope handle pattern access exceptions ?

Parameters:

scope -

Returns:

true if pattern accesses do occur underneath, false otherwise
