public Instruction DIV()

DUP

public Instruction DUP()

identicalTo

public boolean identicalTo(Type other)

LOAD

public Instruction LOAD(int slot)

MUL

public Instruction MUL()

translateBox

public void translateBox(ClassGenerator classGen, MethodGenerator methodGen)

Translates an object of this type to its boxed representation.

translateFrom

public void translateFrom(ClassGenerator classGen, MethodGenerator methodGen, Class clazz)

Translates an external (primitive) Java type into a real. Expects a java object on the stack and pushes a real (i.e., a double).

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, Type type)

Translates a real into an object of internal type type. The translation to int is undefined since reals are never converted to ints.

See Also: Type

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, StringType type)

Expects a real on the stack and pushes its string value by calling Double.toString(double d).

See Also: Type

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, BooleanType type)

Expects a real on the stack and pushes a 0 if that number is 0.0 and a 1 otherwise.

See Also: Type

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, IntType type)

Expects a real on the stack and pushes a truncated integer value

See Also: Type

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, ReferenceType type)

Expects a double on the stack and pushes a boxed double. Boxed double are represented by an instance of java.lang.Double.

See Also: Type

translateTo

public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, Class clazz)

Translates a real into the Java type denoted by clazz. Expects a real on the stack and pushes a number of the appropriate type after coercion.

translateToDesynthesized

public FlowList translateToDesynthesized(ClassGenerator classGen, MethodGenerator methodGen, BooleanType type)

Translates a real into a non-synthesized boolean. It does not push a 0 or a 1 but instead returns branchhandle list to be appended to the false list. A NaN must be converted to "false".

See Also: Type

translateUnBox

public void translateUnBox(ClassGenerator classGen, MethodGenerator methodGen)

Translates an object of this type to its unboxed representation.
