| Constructor Summary | |
| public | CharRange(char ch)
| | public | CharRange(char ch, boolean negated)
| | public | CharRange(char start, char end)
| | public | CharRange(char start, char end, boolean negated)
Constructs a CharRange over a set of characters,
optionally negating the range.
A negated range includes everything except that defined by the
start and end characters.
If start and end are in the wrong order, they are reversed. |
| CharRange | | public CharRange(char ch)(Code) | | Constructs a CharRange over a single character.
Parameters:
ch - only character in this range |
| CharRange | | public CharRange(char ch, boolean negated)(Code) | | Constructs a CharRange over a single character,
optionally negating the range.
A negated range includes everything except the specified char.
Parameters:
ch - only character in this range
Parameters:
negated - true to express everything except the range |
| CharRange | | public CharRange(char start, char end)(Code) | | Constructs a CharRange over a set of characters.
Parameters:
start - first character, inclusive, in this range
Parameters:
end - last character, inclusive, in this range |
| CharRange | | public CharRange(char start, char end, boolean negated)(Code) | | Constructs a CharRange over a set of characters,
optionally negating the range.
A negated range includes everything except that defined by the
start and end characters.
If start and end are in the wrong order, they are reversed.
Thus a-e is the same as e-a.
Parameters:
start - first character, inclusive, in this range
Parameters:
end - last character, inclusive, in this range
Parameters:
negated - true to express everything except the range |
| contains | | public boolean contains(char ch)(Code) | | Is the character specified contained in this range.
Parameters:
ch - the character to check true if this range contains the input character |
| contains | | public boolean contains(CharRange range)(Code) | | Are all the characters of the passed in range contained in
this range.
Parameters:
range - the range to check against true if this range entirely contains the input range
throws:
IllegalArgumentException - if null input |
| equals | | public boolean equals(Object obj)(Code) | | Compares two CharRange objects, returning true if they represent
exactly the same range of characters defined in the same way.
Parameters:
obj - the object to compare to true if equal |
| getEnd | | public char getEnd()(Code) | | Gets the end character for this character range.
the end char (inclusive) |
| getStart | | public char getStart()(Code) | | Gets the start character for this character range.
the start char (inclusive) |
| hashCode | | public int hashCode()(Code) | | Gets a hashCode compatible with the equals method.
a suitable hashCode |
| isNegated | | public boolean isNegated()(Code) | | Is this CharRange negated.
A negated range includes everything except that defined by the
start and end characters.
true is negated |
| toString | | public String toString()(Code) | | Gets a string representation of the character range.
string representation of this range |
