Method Details
-
read
protected Attribute read(ClassReader classReader, int offset, int length, char[] charBuffer, int codeOffset, Label[] labels) Description copied from class:Attribute
Reads aAttribute.type
attribute. This method must return a newAttribute
object, of typeAttribute.type
, corresponding to the 'length' bytes starting at 'offset', in the given ClassReader.- Overrides:
read
in classAttribute
- Parameters:
classReader
- the class that contains the attribute to be read.offset
- index of the first byte of the attribute's content inClassReader
. The 6 attribute header bytes (attribute_name_index and attribute_length) are not taken into account here.length
- the length of the attribute's content (excluding the 6 attribute header bytes).charBuffer
- the buffer to be used to call the ClassReader methods requiring a 'charBuffer' parameter.codeOffset
- index of the first byte of content of the enclosing Code attribute inClassReader
, or -1 if the attribute to be read is not a Code attribute. The 6 attribute header bytes (attribute_name_index and attribute_length) are not taken into account here.labels
- the labels of the method's code, or null if the attribute to be read is not a Code attribute.- Returns:
- a new
Attribute
object corresponding to the specified bytes.
-
write
protected ByteVector write(ClassWriter classWriter, byte[] code, int codeLength, int maxStack, int maxLocals) Description copied from class:Attribute
Returns the byte array form of the content of this attribute. The 6 header bytes (attribute_name_index and attribute_length) must not be added in the returned ByteVector.- Overrides:
write
in classAttribute
- Parameters:
classWriter
- the class to which this attribute must be added. This parameter can be used to add the items that corresponds to this attribute to the constant pool of this class.code
- the bytecode of the method corresponding to this Code attribute, or null if this attribute is not a Code attribute. Corresponds to the 'code' field of the Code attribute.codeLength
- the length of the bytecode of the method corresponding to this code attribute, or 0 if this attribute is not a Code attribute. Corresponds to the 'code_length' field of the Code attribute.maxStack
- the maximum stack size of the method corresponding to this Code attribute, or -1 if this attribute is not a Code attribute.maxLocals
- the maximum number of local variables of the method corresponding to this code attribute, or -1 if this attribute is not a Code attribute.- Returns:
- the byte array form of this attribute.
