方法详细信息

getType

public static Type getType(String typeDescriptor)

Returns the Java type corresponding to the given type descriptor.

参数：

typeDescriptor - a type descriptor.

返回：

the Java type corresponding to the given type descriptor.

getArgumentsAndReturnSizes

public static int getArgumentsAndReturnSizes(String desc)

Computes the size of the arguments and of the return value of a method.

参数：

desc - the descriptor of a method.

返回：

the size of the arguments of the method (plus one for the implicit this argument), argSize, and the size of its return value, retSize, packed into a single int i = (argSize << 2) | retSize (argSize is therefore equal to i >> 2, and retSize to i & 0x03).

getSort

public int getSort()

Returns the sort of this Java type.

返回：

VOID, BOOLEAN, CHAR, BYTE, SHORT, INT, FLOAT, LONG, DOUBLE, ARRAY or OBJECT.

getInternalName

public String getInternalName()

Returns the internal name of the class corresponding to this object or array type. The internal name of a class is its fully qualified name (as returned by Class.getName(), where '.' are replaced by '/'. This method should only be used for an object or array type.

返回：

the internal name of the class corresponding to this object type.
