    • EncodedValueReader

      public EncodedValueReader(ByteInput in, int knownType)
      Creates a new encoded value reader whose only value is the specified known type. This is useful for encoded values without a type prefix, such as class_def_item's encoded_array or annotation_item's encoded_annotation.

  • Method Details

    • peek

      public int peek()
      Returns the type of the next value to read.

    • readArray

      public int readArray()
      Begins reading the elements of an array, returning the array's size. The caller must follow up by calling a read method for each element in the array. For example, this reads a byte array: 
         
   int arraySize = readArray();
   for (int i = 0, i < arraySize; i++) {
     readByte();
   }

    • readAnnotation

      public int readAnnotation()
      Begins reading the fields of an annotation, returning the number of fields. The caller must follow up by making alternating calls to readAnnotationName() and another read method. For example, this reads an annotation whose fields are all bytes: 
         
   int fieldCount = readAnnotation();
   int annotationType = getAnnotationType();
   for (int i = 0; i < fieldCount; i++) {
       readAnnotationName();
       readByte();
   }

    • getAnnotationType

      public int getAnnotationType()
      Returns the type of the annotation just returned by readAnnotation(). This method's value is undefined unless the most recent call was to readAnnotation().

    • readAnnotationName

      public int readAnnotationName()

    • readByte

      public byte readByte()

    • readShort

    • readInt

      public int readInt()

    • readLong

      public long readLong()

    • readFloat

      public float readFloat()

    • readDouble

      public double readDouble()

    • readMethodType

      public int readMethodType()

    • readMethodHandle

      public int readMethodHandle()

    • readString

      public int readString()

    • readType

      public int readType()

    • readField

      public int readField()

    • readEnum

    • readNull

      public void readNull()

    • readBoolean

      public boolean readBoolean()

    • skipValue

      public void skipValue()
      Skips a single value, including its nested values if it is an array or annotation.
