- Method Detail
  - getByteValue
```
public byte getByteValue()
```
    Description copied from class: Field
    
    Get field as a byte value.
    
    Overrides:
    
    getByteValue in class Field
    
    Returns:
    
    byte value
  - setByteValue
```
public void setByteValue(byte value)
```
    Description copied from class: Field
    
    Set field's byte value.
    
    Overrides:
    
    setByteValue in class Field
    
    Parameters:
    
    value - byte value
  - getValueAsString
```
public java.lang.String getValueAsString()
```
    Description copied from class: Field
    
    Get field value as a formatted string
    
    Specified by:
    
    getValueAsString in class Field
    
    Returns:
    
    field value string
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Description copied from class: Field
    
    Determine if the specified Object is another Field which has the same type and value as this Field. When comparing a PrimitiveField, with a null state, a value of zero (0) is used.
    
    Specified by:
    
    equals in class Field
    
    Parameters:
    
    obj - another object
    
    Returns:
    
    true if this field equals obj
  - compareTo
```
public int compareTo(Field o)
```
    Description copied from class: Field
    
    Compares this Field with another Field for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified Field.
    NOTE: Field objects do not fully comply with the Comparable interface. Only the same Field implementations may be compared. In addition, the null state is not considered when comparing PrimitiveFields which have a zero (0) value.
    
    Specified by:
    
    compareTo in interface java.lang.Comparable<Field>
    
    Specified by:
    
    compareTo in class Field
    
    Parameters:
    
    o - another Field which is the same type as this Field
    
    Returns:
    
    field comparison result (see Comparable.compareTo(Object)).
  - copyField
```
public ByteField copyField()
```
    Description copied from class: Field
    
    Create new instance of this field with the same value.
    
    Specified by:
    
    copyField in class Field
    
    Returns:
    
    new field instance with same value
  - newField
```
public ByteField newField()
```
    Description copied from class: Field
    
    Create new instance of this field type.
    
    Specified by:
    
    newField in class Field
    
    Returns:
    
    new field instance with undefined initial value
  - getLongValue
```
public long getLongValue()
```
    Description copied from class: Field
    
    Get field as a long value. All fixed-length field objects must implement this method
    
    Overrides:
    
    getLongValue in class Field
    
    Returns:
    
    long value
  - setLongValue
```
public void setLongValue(long value)
```
    Description copied from class: Field
    
    Set field's long value. All fixed-length field objects must implement this method
    
    Overrides:
    
    setLongValue in class Field
    
    Parameters:
    
    value - long value
  - getBinaryData
```
public byte[] getBinaryData()
```
    Description copied from class: Field
    
    Get data as a byte array.
    
    Specified by:
    
    getBinaryData in class Field
    
    Returns:
    
    byte[]
  - setBinaryData
```
public void setBinaryData(byte[] bytes)
```
    Description copied from class: Field
    
    Set data from binary byte array. All variable-length fields must implement this method.
    
    Specified by:
    
    setBinaryData in class Field
    
    Parameters:
    
    bytes - field data
  - hashCode
```

  - isNull
```
public final boolean isNull()
```
    Description copied from class: Field
