Method Detail
- getSignature
```
public java.lang.String getSignature()
```
- getType
```
public byte getType()
```
- getSize
```
public int getSize()
```
  Returns:
  
  stack size of this type (2 for long and double, 0 for void, 1 otherwise)
- toString
```
public java.lang.String toString()
```
  Overrides:
  
  toString in class java.lang.Object
  
  Returns:
  
  Type string, e.g. 'int[]'
- getType
```
public static final Type getType(java.lang.String signature)
```
- getTypeInternal
```
public static final Type.TypeHolder getTypeInternal(java.lang.String signature)
                                             throws java.lang.StringIndexOutOfBoundsException
```
  Convert signature to a Type object.
  
  Parameters:
  
  signature - signature string such as Ljava/lang/String;
  
  Returns:
  
  type object
  
  Throws:
  
  java.lang.StringIndexOutOfBoundsException
- getReturnType
```
public static Type getReturnType(java.lang.String signature)
```
  Convert return value of a method (signature) to a Type object.
  
  Parameters:
  
  signature - signature string such as (Ljava/lang/String;)V
  
  Returns:
  
  return type
- getArgumentTypes
```
public static Type[] getArgumentTypes(java.lang.String signature)
```
  Convert arguments of a method (signature) to an array of Type objects.
  
  Parameters:
  
  signature - signature string such as (Ljava/lang/String;)V
  
  Returns:
  
  array of argument types
- getArgumentSizes
```
public static int getArgumentSizes(java.lang.String signature)
```
  Work out the type of each argument in the signature and return the cumulative sizes of all the types (size means number of stack slots it consumes, eg double=2, int=1). Unlike the call above, this does minimal unpacking
- getTypeSize
```
public static int getTypeSize(java.lang.String signature)
```
  Return the size of the type expressed in the signature. The signature should contain only one type.
- getType
```
public static Type getType(java.lang.Class cl)
```
  Convert runtime java.lang.Class to BCEL Type object.
  
  Parameters:
  
  cl - Java class
  
  Returns:
  
  corresponding Type object
- getSignature
```
public static java.lang.String getSignature(java.lang.reflect.Method meth)
```
- getSignature
```
public static java.lang.String getSignature(java.lang.reflect.Constructor<?> cons)
```
