Class ClassReader.AttrIterator

  • Enclosing class:
    ClassReader
    public static final class ClassReader.AttrIterator
extends java.lang.Object
    AttrIterator provides access to attributes in the class file.

    AttrIterators can be reused for many different iterations, like this: 

       AttrIterator iter = new AttrIterator();
    int fieldCount = reader.getFieldCount();
    for (int i = 0; i < fieldCount; i++) {
      reader.initFieldAttributeIterator(i, iter);
      for (; iter.isValid(); iter.advance()) {
        if (iter.getName().equals("ConstantValue")) {
          ConstantValueReader cv = new ConstantValueReader(iter);
          ...
        }
      }
    }

    • Constructor Detail

      • AttrIterator

        public AttrIterator()
        Create a blank iterator. The iterator is not valid until it is initialized by some other class.

    • Method Detail

      • getRawOffset

        public int getRawOffset()
        The attribute iterator must be valid.
        Returns:
        the offset of the raw attribute data (including attribute header) in the class file data

      • getRawSize

        public int getRawSize()
        The attribute iterator must be valid.
        Returns:
        the size of the raw attribute data (including attribute header) in the class file data

      • getDataOffset

        public int getDataOffset()
        The attribute iterator must be valid.
        Returns:
        the offset of the attribute data (excluding attribute header) in the class file data

      • getDataSize

        public int getDataSize()
        The attribute iterator must be valid.
        Returns:
        the size of the attribute data (excluding attribute header) in the class file data

      • getRemainingAttributesCount

        public int getRemainingAttributesCount()
        Returns:
        the number of attributes left in the list, including this attribute (if valid)

      • getNameIndex

        public int getNameIndex()
        The attribute iterator must be valid.
        Returns:
        the constant pool index of the name of the attribute

      • isValid

        public boolean isValid()
        Returns:
        whether this iterator is valid

      • advance

        public void advance()
        The attribute iterator must be valid.

        The iterator is advanced to the next attribute (which might not exist, so the iterator might become invalid).
