protected AbstractCharSequenceAssert(A actual,
                          Class<?> selfType)
```
- Method Detail
  - isNullOrEmpty
```
public void isNullOrEmpty()
```
    Verifies that the actual CharSequence is empty, i.e., it has a length of 0, or is null.
    If you do not want to accept a null value, use isEmpty() instead.
    Both of these assertions will succeed:
```
 String emptyString = ""
 assertThat(emptyString).isNullOrEmpty();
 
 String nullString = null;
 assertThat(nullString).isNullOrEmpty();
 
```
    Specified by:
    
    isNullOrEmpty in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Throws:
    
    AssertionError - if the actual CharSequence has a non-zero length.
  - isEmpty
```
public void isEmpty()
```
    Verifies that the actual CharSequence is empty, i.e., it has a length of 0 and is not null.
    If you want to accept a null value as well as a 0 length, use isNullOrEmpty() instead.
    This assertion will succeed:
```
 String emptyString = ""
 assertThat(emptyString).isEmpty();
 
```
    Whereas this assertion will fail:
```
 String nullString = null;
 assertThat(nullString).isEmpty();
 
```
    Specified by:
    
    isEmpty in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Throws:
    
    AssertionError - if the actual CharSequence has a non-zero length or is null.
  - isNotEmpty
```
public S isNotEmpty()
```
    Verifies that the actual CharSequence is not empty, i.e., is not null and has a length of 1 or more.
    This assertion will succeed:
```
 String bookName = "A Game of Thrones"
 assertThat(bookName).isNotEmpty();
 
```
    Whereas this assertion will fail:
```
 String emptyString = ""
 assertThat(emptyString).isNotEmpty();
 
```
    Specified by:
    
    isNotEmpty in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Returns:
    this assertion object.
    
    Throws:
    
    AssertionError - if the actual CharSequence is empty (has a length of 0).
  - hasSize
```
public S hasSize(int expected)
```
    Verifies that the actual CharSequence has the expected length using the length() method.
    This assertion will succeed:
```
 String bookName = "A Game of Thrones"
 assertThat(bookName).hasSize(17);
 
```
    Whereas this assertion will fail:
```
 String bookName = "A Clash of Kings"
 assertThat(bookName).hasSize(4);
 
```
    Specified by:
    
    hasSize in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Parameters:
    expected - the expected length of the actual CharSequence.
    
    Returns:
    this assertion object.
    
    Throws:
    
    AssertionError - if the actual length is not equal to the expected length.
  - hasLineCount
```
public S hasLineCount(int expectedLineCount)
```
    Verifies that the actual CharSequence has the expected line count.
    A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed (see LineNumberReader).
    This assertion will succeed:
```
 String multiLine = "First line\n" +
                    "Last line";
 assertThat(multiLine).hasLineCount(2);
 
```
    Whereas this assertion will fail:
```
 String bookName = "A Clash of Kings";
 assertThat(bookName).hasLineCount(3);
 
```
    Parameters:
    expectedLineCount - the expected line count of the actual CharSequence.
    
    Returns:
    this assertion object.
    
    Throws:
    
    AssertionError - if the actual line count is not equal to the expected one.
  - hasSameSizeAs
```
public S hasSameSizeAs(CharSequence other)
```
    Verifies that the actual CharSequence has a length that's the same as the length of the given CharSequence.
    Examples :

@Deprecated
public final S usingElementComparator(Comparator<? super Character> customComparator)
```
    Deprecated. Custom element Comparator is not supported for CharSequence comparison.
    
    Do not use this method.
    
    Specified by:
    
    usingElementComparator in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Parameters:
    customComparator - the comparator to use for incoming assertion checks.
    
    Returns:
    this assertion object.
    
    Throws:
    
    UnsupportedOperationException - if this method is called.
  - usingDefaultElementComparator
```
@Deprecated
public final S usingDefaultElementComparator()
```
    Deprecated. Custom element Comparator is not supported for CharSequence comparison.
    
    Do not use this method.
    
    Specified by:
    
    usingDefaultElementComparator in interface EnumerableAssert<S extends AbstractCharSequenceAssert<S,A>,Character>
    
    Returns:

    Throws:
    
    UnsupportedOperationException - if this method is called.
  - usingComparator
```
public S usingComparator(Comparator<? super A> customComparator)
```
    Description copied from class: AbstractAssert
    Use given custom comparator instead of relying on actual type A equals method for incoming assertion checks.
    Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.
    Examples :
```
 // frodo and sam are instances of Character with Hobbit race (obviously :).
 // raceComparator implements Comparator<Character> 
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); 
 
```
    Specified by:
    
    usingComparator in interface Assert<S extends AbstractCharSequenceAssert<S,A>,A extends CharSequence>
    
    Overrides:
    
    usingComparator in class AbstractAssert<S extends AbstractCharSequenceAssert<S,A>,A extends CharSequence>
    
    Parameters:
    customComparator - the comparator to use for incoming assertion checks.
    
    Returns:
    this assertion object.
  - usingDefaultComparator
```
public S usingDefaultComparator()
```
    Description copied from class: AbstractAssert
    
    Revert to standard comparison for incoming assertion checks.
    This method should be used to disable a custom comparison strategy set by calling Assert.usingComparator(Comparator).
    
    Specified by:
    
    usingDefaultComparator in interface Assert<S extends AbstractCharSequenceAssert<S,A>,A extends CharSequence>
    
    Overrides:
    
    usingDefaultComparator in class AbstractAssert<S extends AbstractCharSequenceAssert<S,A>,A extends CharSequence>
    
    Returns:
    this assertion object.
  - inHexadecimal
```
public S inHexadecimal()
```
    Description copied from class: AbstractAssert
    Use hexadecimal object representation instead of standard representation in error messages.
    It can be useful when comparing UNICODE characters - many unicode chars have duplicate characters assigned, it is thus impossible to find differences from the standard error message:
    With standard message:
```
 assertThat("µµµ").contains("μμμ");

 java.lang.AssertionError:
 Expecting:
   <"µµµ">
 to contain:
   <"μμμ">

    Use unicode character representation instead of standard representation in error messages.
    It can be useful when comparing UNICODE characters - many unicode chars have duplicate characters assigned, it is thus impossible to find differences from the standard error message:
    With standard message:
```
