```
    Sets integer values into this tag. This method should be used for tags of type TYPE_UNSIGNED_SHORT. This method will fail if:
    The component type of this tag is not TYPE_UNSIGNED_SHORT, TYPE_UNSIGNED_LONG, or TYPE_LONG.
    The value overflows.
    The value.length does NOT match the component count in the definition for this tag.

```
    Sets integer value into this tag. This method should be used for tags of type TYPE_UNSIGNED_SHORT, or TYPE_LONG. This method will fail if:
    The component type of this tag is not TYPE_UNSIGNED_SHORT, TYPE_UNSIGNED_LONG, or TYPE_LONG.
    The value overflows.
    The component count in the definition of this tag is not 1.
  - setValue
```
 boolean setValue(Array<long> value)
```

  - setValue
```

```
    Sets a string value into this tag. This method should be used for tags of type TYPE_ASCII. The string is converted to an ASCII string. Characters that cannot be converted are replaced with '?'. The length of the string must be equal to either (component count -1) or (component count). The final byte will be set to the string null terminator '\0', overwriting the last character in the string if the value.length is equal to the component count. This method will fail if:
    The data type is not TYPE_ASCII or TYPE_UNDEFINED.
    The length of the string is not equal to (component count -1) or (component count) in the definition for this tag.

    The value overflows.
    The value.length does NOT match the component count in the definition for this tag.
  - setValue
```
 boolean setValue(Rational value)
```
    Sets a Rational value into this tag. This method should be used for tags of type TYPE_UNSIGNED_RATIONAL, or TYPE_RATIONAL. This method will fail if:

    The component type of this tag is not TYPE_UNSIGNED_BYTE or TYPE_UNDEFINED .
    The length does NOT match the component count in the definition for this tag.
  - setValue
```
 boolean setValue(Array<byte> value)
```
    Equivalent to setValue(value, 0, value.length).
  - setValue
```
