Method Detail

get

public static ValuesFilter get(char kind)

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12).

Overrides:

numArgs in class Procedure

matches

public static boolean matches(java.lang.Object result,
                              long count)

apply

public void apply(CallContext ctx)
           throws java.lang.Throwable

Description copied from class: Procedure

Call this Procedure using the explicit-CallContext-convention. The input arguments are (by default) in stack.args; the result is written to ctx.consumer.

Overrides:

apply in class Procedure

Throws:

java.lang.Throwable

inline

public Expression inline(ApplyExp exp,
                         InlineCalls walker,
                         boolean argsInlined)

Description copied from interface: CanInline

Inline an application of this Procedure and return result. Unless argsInlined is true, then this method is responsible for walking exp.getArgs(); you can handle this using exp.getArgs(walker, argsInlined). (The exp.getFunction() has been walked, regardless.)

Specified by:

inline in interface CanInline

argsInlined - true if the arguments have been inlined. Can return original expression.

compile

public void compile(ApplyExp exp,
                    Compilation comp,
                    Target target)

Specified by:

compile in interface Inlineable

getReturnType

public Type getReturnType(Expression[] args)

Specified by:

getReturnType in interface Inlineable
