ClassReader.AttrIterator (WALA Shrike 1.5.1 API)

java.lang.Object
- com.ibm.wala.shrikeCT.ClassReader.AttrIterator

Enclosing class:: ClassReader

public static final class ClassReader.AttrIterator
extends 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
  - getClassReader
```
public ClassReader getClassReader()
```
  - 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
  - getName
```
public String getName()
               throws InvalidClassFileException
```
    The attribute iterator must be valid.
    
    Returns:
    
    the name of the attribute
    
    Throws:
    
    InvalidClassFileException
  - 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).
