Constructor Detail

SpaceNode

public SpaceNode(FixedGlue theWidth)

Creates a new object.

Parameters:

theWidth - the size of the space

Method Detail

toString

public void toString(java.lang.StringBuffer sb,
                     java.lang.String prefix,
                     int breadth,
                     int depth)

This method puts the printable representation into the string buffer. This is meant to produce a exhaustive form as it is used in tracing output to the log file.

Specified by:

toString in interface Node

Overrides:

toString in class GlueNode

Parameters:

sb - the output string buffer

prefix - the prefix string inserted at the beginning of each line

breadth - the breadth of the nodes to display

depth - the depth of the nodes to display

See Also:

Node.toString( java.lang.StringBuffer, java.lang.String, int, int)

toText

public void toText(java.lang.StringBuffer sb,
                   java.lang.String prefix)

This method puts the printable representation into the string buffer. This is meant to produce a short form only as it is used in error messages to the user.

Specified by:

toText in interface Node

Overrides:

toText in class GlueNode

Parameters:

sb - the output string buffer

prefix - the prefix string inserted at the beginning of each line

See Also:

Node.toText( java.lang.StringBuffer, java.lang.String)

visit

public java.lang.Object visit(NodeVisitor visitor,
                              java.lang.Object value)
                       throws GeneralException

This method provides an entry point for the visitor pattern.

Specified by:

visit in interface Node

Overrides:

visit in class GlueNode

Parameters:

visitor - the visitor to apply

value - the argument for the visitor

Returns:

the result of the method invocation of the visitor

Throws:

GeneralException - in case of an error
