Method Detail

getMinimumLength

int getMinimumLength()

Overrides:

getMinimumLength in class REToken

---

getMaximumLength

int getMaximumLength()

Overrides:

getMaximumLength in class REToken

---

matchThis

REMatch matchThis(CharIndexed input,
                  REMatch mymatch)

Description copied from class: REToken

Returns true if the match succeeded, false if it failed. The matching is done against this REToken only. Chained tokens are not checked. This method is used to define the default match method. Simple subclasses of REToken, for example, such that matches only one character, should implement this method. Then the default match method will work. But complicated subclasses of REToken, which needs a special match method, do not have to implement this method.

Overrides:

matchThis in class REToken

---

matchOneChar

private boolean matchOneChar(char ch)

---

returnsFixedLengthMatches

boolean returnsFixedLengthMatches()

Overrides:

returnsFixedLengthMatches in class REToken

---

findFixedLengthMatches

int findFixedLengthMatches(CharIndexed input,
                           REMatch mymatch,
                           int max)

Overrides:

findFixedLengthMatches in class REToken

---

dump

void dump(java.lang.StringBuffer os)

Specified by:

dump in class REToken

---

getHandler

private RETokenNamedProperty.Handler getHandler(java.lang.String name)
                                         throws REException

---

clone

public java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

setUncle

void setUncle(REToken anUncle)

---

match

boolean match(CharIndexed input,
              REMatch mymatch)

Returns true if the match succeeded, false if it failed.

---

next

protected boolean next(CharIndexed input,
                       REMatch mymatch)

Returns true if the rest of the tokens match, false if they fail.

---

getNext

REToken getNext()

Returns the next REToken chained to this REToken.

---

findMatch

REMatch findMatch(CharIndexed input,
                  REMatch mymatch)

Finds a match at the position specified by the given REMatch. If necessary, adds a BacktrackStack.Backtrack object to backtrackStack of the REmatch found this time so that another possible match may be found when backtrack is called. By default, nothing is added to the backtrackStack.

---

backtrack

REMatch backtrack(CharIndexed input,
                  REMatch mymatch,
                  java.lang.Object param)

Backtrack to another possibility. Ordinary REToken cannot do anything if this method is called.

---

chain

boolean chain(REToken token)

---

dumpAll

void dumpAll(java.lang.StringBuffer os)

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

toLowerCase

public static char toLowerCase(char ch,
                               boolean unicodeAware)

Converts the character argument to lowercase.

---

toUpperCase

public static char toUpperCase(char ch,
                               boolean unicodeAware)

Converts the character argument to uppercase.
