Constructor Detail

WordExpression

public WordExpression(java.lang.String postfix,
                      boolean swallowPostFix,
                      boolean allowDigit,
                      boolean noLineFeed)

---

WordExpression

public WordExpression(java.lang.String postfix,
                      boolean swallowPostFix,
                      boolean allowDigit)

Allow line-feed's, i.e. expression may span more than one line.

---

WordExpression

public WordExpression(java.lang.String postfix,
                      boolean swallowPostFix)

Constructor with allowsDigit=false (i.e. only alphabetic character are swallowed if postfix = null), and which allows linefeeds.

---

WordExpression

public WordExpression()

Parse an expression containing letters only, and stops when a non-letter char is found. Allows line-feed's, which can be removed later on using Context.removeLineFeeds (static method).

Method Detail

interpret

public boolean interpret(Context context)
                  throws ParserException

Description copied from class: AbstractRegularExpression

Parses this expression, possibly using Context to fetch the String to interpret if this Expression is a leaf expression.

Specified by:

interpret in class AbstractRegularExpression

---

getValue

public java.lang.String getValue()

Return the (last) parsed content of this expression

---

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()).
