Field Detail

value

public String value

(¬ø) The text representing the constant.

Constructor Detail

Constant

public Constant(TokenValue token)

Parser's constructor.

Parameters:

token - The parser's token for the constant.

Constant

public Constant(String value)

Initializing constructor. The line and byte offset, having not been specified, are both set to -1.

Parameters:

value - The text representation of the constant.

Constant

public Constant(int line,
                int byteOffset,
                String value)

Full constructor.

Parameters:

line - The line on which the source code represented by this node is found.

byteOffset - The byte offset from the beginning of the source file at which the source code represented by this node is found.

value - The text representation of the constant.

Method Detail

noQuotes

public String noQuotes()

Returns the contents of value removing unescaped double quotes.

Returns:

The contents of value with unescaped double quotes removed.

hashCode

public int hashCode()

Returns a hash code value for java hash structures.

Overrides:

hashCode in class Object

Returns:

A hash code for this object.

equals

public boolean equals(Object o)

Two constants are equal when their noQuotes() methods return the same thing.

Overrides:

equals in class Object

Returns:

true iff this object is the same as the argument.

noQuotes()

iterator

public ASTNodeIterator iterator()

Returns an iterator used to successively access the children of this node.

Specified by:

iterator in class ASTNode

Returns:

An iterator used to successively access the children of this node.

clone

public Object clone()

Creates a new object with the same primitive data, and recursively creates new member data objects as well.

Overrides:

clone in class ASTNode

Returns:

The clone node.

runPass

public void runPass(Pass pass)

Ensures that the correct run() method is called for this type of node.

Specified by:

runPass in class ASTNode

Parameters:

pass - The pass whose run() method should be called.

write

public void write(StringBuffer buffer)

Writes a string representation of this ASTNode to the specified buffer. The representation written is parsable by the LBJava compiler, but not very readable.

Specified by:

write in class ASTNode

Parameters:

buffer - The buffer to write to.
