Method Detail

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.

Overrides:

numArgs in class Procedure

subList

public static void subList(java.lang.Object seq,
           double start,
           double end,
           Consumer out)

apply

public void apply(CallContext ctx)

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
