Method Details

insertStatement

public static Statement insertStatement(Statement s1,
 Statement s2)

Insert a bit of code at the front of a statement. Side-effect s2, if it is a CompoundStatement.

setLabel

public void setLabel(Environment env,
 Expression e)

Set the label of a statement

checkMethod

public Vset checkMethod(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp)

Check a statement

checkDeclaration

Vset checkDeclaration(Environment env,
 Context ctx,
 Vset vset,
 int mod,
 Type t,
 Hashtable<Object,Object> exp)

checkLabel

protected void checkLabel(Environment env,
 Context ctx)

Make sure the labels on this statement do not duplicate the labels on any enclosing statement. Provided as a convenience for subclasses.

check

Vset check(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp)

checkBlockStatement

Vset checkBlockStatement(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp)

This is called in contexts where declarations are valid.

reach

Vset reach(Environment env,
 Vset vset)

inline

public Statement inline(Environment env,
 Context ctx)

Inline

eliminate

public Statement eliminate(Environment env,
 Statement s)

Eliminate this statement, which is only possible if it has no label.

code

public void code(Environment env,
 Context ctx,
 Assembler asm)

Code

codeFinally

void codeFinally(Environment env,
 Context ctx,

 Context stopctx,
 Type save)

Generate the code to call all finally's for a break, continue, or return statement. We must call "jsr" on all the cleanup code between the current context "ctx", and the destination context "stopctx". If 'save' isn't null, there is also a value on the top of the stack

hasLabel

public boolean hasLabel(Identifier lbl)

firstConstructor

public Expression firstConstructor()

Check if the first thing is a constructor invocation

copyInline

public Statement copyInline(Context ctx,
 boolean valNeeded)

Create a copy of the statement for method inlining

costInline

public int costInline(int thresh,
 Environment env,
 Context ctx)

printIndent

void printIndent(PrintStream out,
 int indent)

Print

print

public void print(PrintStream out,
