Constructor Detail

RetBlock

public RetBlock(Instruction bytecodeInstr,
                LocalInfo local)

Method Detail

fillInGenSet

public void fillInGenSet(Set in,
                         Set gen)

Fill all in variables into the given VariableSet.

Overrides:

fillInGenSet in class StructuredBlock

Parameters:

in - The VariableSet, the in variables should be stored to.

mapStackToLocal

public VariableStack mapStackToLocal(VariableStack stack)

This does take the instr into account and modifies stack accordingly. It then calls super.mapStackToLocal.

Overrides:

mapStackToLocal in class StructuredBlock

Parameters:

stack - the stack before the instruction is called

Returns:

stack the stack afterwards.

getDeclarables

public Set getDeclarables()

Overrides:

getDeclarables in class StructuredBlock

dumpInstruction

public void dumpInstruction(TabbedPrintWriter writer)
                     throws IOException

Description copied from class: StructuredBlock

Print the instruction expressing this structured block.

Specified by:

dumpInstruction in class StructuredBlock

Parameters:

writer - The tabbed print writer, where we print to.

Throws:

IOException
