Class ToStringBuilder

java.lang.Object

com.whitestein.lsps.lang.exec.ToStringBuilder

public final class ToStringBuilder
extends Object

Helper class which builds string representation for the language objects. This implementation can handle also recursive object graphs. Objects are compared using Object.equals(Object) and Object.hashCode(). Infinite object graphs (graphs which always create new objects on traversal) will cause infinite cycle.

Returns a string representation for given object.

Parameters:

object -

expandRecords -

Returns:

a string representation for given object

Throws:

IllegalArgumentException - if object has no language type

toString

public static String toString(Object object,
                              boolean expandRecords,
                              Namespace namespace)

Returns a string representation for given object. If the given namespace is not null, then toString() method defined in record types is used to print records.

Parameters:

object -

expandRecords -

namespace -

Returns:

a string representation for given object

Throws:

IllegalArgumentException - if object has no language type

toString

                              Namespace namespace,
                              String nullString)

Returns a string representation for given object.

Parameters:

object -

namespace -

nullString - string representation of null

Returns:

a string representation for given object

append
