Method Detail

getType

public static Type getType(String typeDescriptor)

Returns the Java type corresponding to the given type descriptor.

Parameters:: typeDescriptor - a type descriptor.
Returns:: 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.

Parameters:: desc - the descriptor of a method.
Returns:: 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.

Returns:: 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.

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

getDescriptor

public String getDescriptor()

Returns the descriptor corresponding to this Java type.

Returns:: the descriptor corresponding to this Java type.
