public void setType(JvmType.Clazz t)

constantPool

public java.util.ArrayList<Constant.Info> constantPool()

This method builds a constant pool for this class file.

Returns:

descriptor

public static java.lang.String descriptor(JvmType t,
                                          boolean generic)

This method returns a JVM descriptor string for the type in question. The format of the string is defined in "The JavaTM Virtual Machine Specification, 2nd ed", Section 4.3. Example descriptor strings include:

Type	Descriptor
int
I
boolean
Z
float[]
F[
java.lang.Integer
Ljava/lang/Integer;
int(Double,Float)
(DF)I

The descriptor string is used, amongst other things, to uniquely identify a class in the ClassTable.

See the JVM Specification for more information.

Parameters:

t - The type to generate the descriptor for

generic - True indicates generic information should be included.

Returns:

slotSize

public static int slotSize(JvmType type)

Determine the slot size for the corresponding Java type.

Parameters:

type - The type to determine the slot size for.

Returns:

the slot size in slots.
