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. Labels defined in the attribute must be created and added to this array, if not already present, by calling theAttribute.readLabel(org.eclipse.persistence.internal.libraries.asm.ClassReader, int, org.eclipse.persistence.internal.libraries.asm.Label[])
method (do not createLabel
instances directly).- 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.This method is only invoked once to compute the binary form of this attribute. Subsequent changes to the attribute after it was written for the first time will not be considered.
- 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.
