protected Attribute read(final ClassReader classReader, final int offset, final int length, final char[] charBuffer, final int codeOffset, final Label[] labels)

Overrides org.objectweb.asm.Attribute.read.

Doc from org.objectweb.asm.Attribute.read.

Reads a type attribute. This method must return a new Attribute object, of type type, corresponding to the 'length' bytes starting at 'offset', in the given ClassReader.

Parameters
classReader:ClassReader

the class that contains the attribute to be read.

offset:int

index of the first byte of the attribute's content in ClassReader. The 6 attribute header bytes (attribute_name_index and attribute_length) are not taken into account here.

length:int

the length of the attribute's content (excluding the 6 attribute header bytes).

charBuffer:char[]

the buffer to be used to call the ClassReader methods requiring a 'charBuffer' parameter.

codeOffset:int

index of the first byte of content of the enclosing Code attribute in ClassReader, 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:Label[]

the labels of the method's code, or null if the attribute to be read is not a Code attribute.

Returns:Attribute

a new Attribute object corresponding to the specified bytes.

protected ByteVector write(final ClassWriter classWriter, final byte[] code, final int codeLength, final int maxStack, final int maxLocals)

Overrides org.objectweb.asm.Attribute.write.

Doc from org.objectweb.asm.Attribute.write.

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.

Parameters
classWriter: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:byte[]

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:int

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:int

the maximum stack size of the method corresponding to this Code attribute, or -1 if this attribute is not a Code attribute.

maxLocals:int

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:ByteVector

the byte array form of this attribute.
