Constructor Detail

StringLiteral

public StringLiteral(java.lang.String s)

Constructs a string literal with the specified string value.

Method Detail

clone

public StringLiteral clone()

Returns a clone of the string literal.

Overrides:

clone in class Literal

Returns:

a deep copy of this expression.

defaultPrint

public static void defaultPrint(StringLiteral l,
                java.io.PrintWriter o)

Prints a literal to a stream.

Parameters:

l - The literal to print.

o - The writer on which to print the literal.

toString

public java.lang.String toString()

Returns a string representation of the string literal.

Overrides:

toString in class Expression

equals

public boolean equals(java.lang.Object o)

Compares the string literal with the specified object for equality.

Overrides:

equals in class Expression

Parameters:

o - the object to be compared with.

Returns:

true if o!=null, this.getClass()==o.getClass(), and this.children.equals(o.children) || this.children==o.children==null

getValue

public java.lang.String getValue()

Returns the value of the string literal.

setClassPrintMethod

public static void setClassPrintMethod(java.lang.reflect.Method m)

Overrides the class print method, so that all subsequently created objects will use the supplied method.

Parameters:

m - The new print method.

setValue

public void setValue(java.lang.String value)

Sets the value of the literal with the specified string value.

stripQuotes

public void stripQuotes()

Removes outer quotes from the string; this class automatically prints quotes around the string so it does not need to store them. Thus, if you create a StringLiteral with a String that already has quotes around it, you will have double quotes, and may need to call this method. The method has no effect if there are no quotes.
