Constructor Detail

Type

private Type(int sort,
             java.lang.String valueBuffer,
             int valueBegin,
             int valueEnd)

Method Detail

getArgumentTypes

static Type[] getArgumentTypes(java.lang.String methodDescriptor)

Returns the Type values corresponding to the argument types of the given method descriptor.

Parameters:

methodDescriptor - a method descriptor.

Returns:

the Type values corresponding to the argument types of the given method descriptor.

getTypeInternal

static Type getTypeInternal(java.lang.String descriptorBuffer,
                            int descriptorBegin,
                            int descriptorEnd)

Returns the Type corresponding to the given field or method descriptor.

Parameters:

descriptorBuffer - a buffer containing the field or method descriptor.

descriptorBegin - the beginning index, inclusive, of the field or method descriptor in descriptorBuffer.

descriptorEnd - the end index, exclusive, of the field or method descriptor in descriptorBuffer.

Returns:

the Type corresponding to the given type descriptor.

getDescriptor

public java.lang.String getDescriptor()

Returns the descriptor corresponding to this type.

Returns:

the descriptor corresponding to this type.

getArgumentsAndReturnSizes

public static int getArgumentsAndReturnSizes(java.lang.String methodDescriptor)

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

Parameters:

methodDescriptor - a method descriptor.

Returns:

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

getClassName

public java.lang.String getClassName()

getDimensions

public int getDimensions()
