Class MetaDef.Element

java.lang.Object
  org.eigenbase.xom.ElementDef
      org.eigenbase.xom.MetaDef.Element

All Implemented Interfaces:

Serializable, Cloneable, MetaDef.Definition, MetaDef.FullDefinition, NodeDef

Enclosing class:

MetaDef

public static class MetaDef.Element
extends ElementDef
implements MetaDef.FullDefinition

An Element Definition defines a basic entity of the meta model. Elements are containers for two types of data: attributes and content. Attributes are simple name/value pairs which may take on the full range of Java types. Content consists of other Elements and Strings, either appearing alone or as arrays.

Method Summary

void	display(PrintWriter _out, int _indent) Outputs this node to any PrintWriter, in a formatted fashion with automatic indenting.
boolean	displayDiff(ElementDef _other, PrintWriter _out, int _indent) The displayDiff function compares this element definition against another, compiling a message containing all diffs.
void	displayXML(XMLOutput _out, int _indent) Outputs this element definition in XML to any XMLOutput.
String	getName() Returns the name of this node's tag.

Field Detail

_contentModel_values

public static final String[] _contentModel_values

Allowable values for contentModel.

contentModel

public String contentModel

keepDef

public Boolean keepDef

type

public String type

_class

public String _class

dtdName

public String dtdName

_abstract

public Boolean _abstract

_def

public DOMWrapper _def

doc

public String doc

Doc tags allow documentation to be added to any definition. The documentation will automatically appear in all physical forms of this model, including dtds, java classes, and the xsl transformation.

attributes

public MetaDef.Attribute[] attributes

This array defines all attributes to appear within this class or element.

content

public MetaDef.Content[] content

This array defines all content (objects and arrays) to appear within this class or element. The interpretation of this array depends on the element's defined content model.

any

public MetaDef.Any any

cdata

public MetaDef.CData cdata

code

public String code

This element allows arbitrary Java Code to be attached to any class or element. Code sections are not verified until the final .java class is compiled and should be used sparingly.

MetaDef.Element

public MetaDef.Element(DOMWrapper _def)
                throws XOMException

Throws:

XOMException

Method Detail

getName

public String getName()

Description copied from interface: NodeDef

Returns the name of this node's tag.

Specified by:

getName in interface NodeDef

Overrides:

getName in class ElementDef

display

public void display(PrintWriter _out,
                    int _indent)

Description copied from interface: NodeDef

Outputs this node to any PrintWriter, in a formatted fashion with automatic indenting.

Specified by:

display in interface NodeDef

Parameters:

_out - the PrintWriter to which to write this NodeDef.

_indent - the indentation level for the printout.

displayXML

public void displayXML(XMLOutput _out,
                       int _indent)

Description copied from interface: NodeDef

Outputs this element definition in XML to any XMLOutput.

Specified by:

displayXML in interface NodeDef

Overrides:

displayXML in class ElementDef

Parameters:

_out - the XMLOutput class to display the XML

displayDiff

public boolean displayDiff(ElementDef _other,
                           PrintWriter _out,
                           int _indent)

Description copied from class: ElementDef

The displayDiff function compares this element definition against another, compiling a message containing all diffs. It is used internally by the equals(), diff(), and verifyEquals() functions.

Overrides:

displayDiff in class ElementDef

Parameters:

_other - the ElementDef to which to compare this element.

_out - a PrintWriter to which to display any discovered differences, or null if just doing an equality check (and no diff report is needed).

_indent - the current indentation level (used for nice display of diffs).

Returns:

true if this and other match exactly, false if not.
