public EncodedValueReader(EncodedValue in)

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.

public EncodedValueReader(EncodedValue in,
                          int knownType)

Method Detail

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

public short readShort()

readChar

public char readChar()

readInt

public int readInt()

readLong

public long readLong()

readFloat

public float readFloat()

readDouble

public double readDouble()

readString

public int readString()

readType

public int readType()

readField

public int readField()

readEnum

public int readEnum()

readMethod

public int readMethod()

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.
