public abstract class Attribute extends ClassFileEntry
Abstract superclass for class file attributes

  • Field Details

    • attributeName

      protected final CPUTF8 attributeName

    • attributeNameIndex

      private int attributeNameIndex

  • Constructor Details

    • Attribute

      public Attribute(CPUTF8 attributeName)

  • Method Details

    • doWrite

      protected void doWrite(DataOutputStream dos) throws IOException
      Specified by:
      doWrite in class ClassFileEntry
      Throws:
      IOException

    • equals

      public boolean equals(Object obj)
      Specified by:
      equals in class ClassFileEntry

    • getAttributeName

      protected CPUTF8 getAttributeName()

    • getLength

      protected abstract int getLength()

    • getLengthIncludingHeader

      protected int getLengthIncludingHeader()
      Answer the length of the receiver including its header (the u2 for the attribute name and the u4 for the attribute length). This is relevant when attributes are nested within other attributes - the outer attribute needs to take the inner attribute headers into account when calculating its length.
      Returns:
      int adjusted length

    • getNestedClassFileEntries

      protected ClassFileEntry[] getNestedClassFileEntries()
      Overrides:
      getNestedClassFileEntries in class ClassFileEntry

    • hasBCIRenumbering

      public boolean hasBCIRenumbering()
      Answer true if the receiver needs to have BCI renumbering applied to it; otherwise answer false.
      Returns:
      boolean BCI renumbering required

    • hashCode

      public int hashCode()
      Specified by:
      hashCode in class ClassFileEntry

    • isSourceFileAttribute

      public boolean isSourceFileAttribute()
      Answer true if the receiver is a source file attribute (which gets special handling when the class is built); otherwise answer false.
      Returns:
      boolean source file attribute

    • resolve

      protected void resolve(ClassConstantPool pool)
      Description copied from class: ClassFileEntry
      Allows the constant pool entries to resolve their nested entries.
      Overrides:
      resolve in class ClassFileEntry
      Parameters:
      pool - TODO

    • writeBody

      protected abstract void writeBody(DataOutputStream dos) throws IOException
      Throws:
      IOException
