org.eclipse.ant.internal.ui.dtd.schema
Class SchemaFactory  

java.lang.Object
  org.eclipse.ant.internal.ui.dtd.schema.SchemaFactory

All Implemented Interfaces:

org.xml.sax.ext.DeclHandler

---

public class SchemaFactory

extends java.lang.Object

implements org.xml.sax.ext.DeclHandler

SchemaFactory is a SAX DeclHandler that converts DTD ELEMENT and ATTLIST declarations to schema form on the fly. The only two methods available to external users of SchemaFactory are its constructor and getSchema(). The latter returns the schema built by this process and should not be called until the XML parser to which this handler is attached has finished parsing.

Method Detail

getSchema

---

attributeDecl

public void attributeDecl(java.lang.String eName,
                          java.lang.String aName,
                          java.lang.String type,
                          java.lang.String valueDefault,
                          java.lang.String value)

Description copied from interface: org.xml.sax.ext.DeclHandler

Report an attribute type declaration.

Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", a parenthesized token group with the separator "|" and all whitespace removed, or the word "NOTATION" followed by a space followed by a parenthesized token group with all whitespace removed.

The value will be the value as reported to applications, appropriately normalized and with entity and character references expanded.

Specified by:

attributeDecl in interface org.xml.sax.ext.DeclHandler

---

stripSurroundingParentheses

private java.lang.String stripSurroundingParentheses(java.lang.String aString)

Strips the surrounding parentheses from aString.

i.e.: (true|false) -> true|false

---

getElement

private Element getElement(java.lang.String eName)

---

parseValues

private java.lang.String[] parseValues(java.lang.String type,
                                       char separator)

---

elementDecl

public void elementDecl(java.lang.String name,
                        java.lang.String model)
                 throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.DeclHandler

Report an element type declaration.

The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all parameter entities are fully resolved and all whitespace is removed,and will include the enclosing parentheses. Other normalization (such as removing redundant parentheses or simplifying occurrence indicators) is at the discretion of the parser.

Specified by:

elementDecl in interface org.xml.sax.ext.DeclHandler

---

parseModel

private org.eclipse.ant.internal.ui.dtd.IModel parseModel(java.lang.String model)
                                                   throws org.xml.sax.SAXException

Convert model string to IModel. The fElement variable is an implicit argument to this method, and it sets fBuf, fPos and fLen for use by other parser methods.

---

scanExpr

private org.eclipse.ant.internal.ui.dtd.IModel scanExpr()
                                                 throws org.xml.sax.SAXException

Scan a parenthesized expression starting from the left parenthesis or leftmost operator.

---

scanExpr

private org.eclipse.ant.internal.ui.dtd.IModel scanExpr(org.eclipse.ant.internal.ui.dtd.IModel term)
                                                 throws org.xml.sax.SAXException

Scan a parenthesized expression with the first term in hand.

---

scanElement

private org.eclipse.ant.internal.ui.dtd.IModel scanElement()
                                                    throws org.xml.sax.SAXException

Scan an element name or a parenthesized sub-expression.

---

checkLen

private void checkLen()
               throws org.xml.sax.SAXException

---

externalEntityDecl

public void externalEntityDecl(java.lang.String name,
                               java.lang.String publicId,
                               java.lang.String systemId)

Description copied from interface: org.xml.sax.ext.DeclHandler

Report a parsed external entity declaration.

Only the effective (first) declaration for each entity will be reported.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

Specified by:

externalEntityDecl in interface org.xml.sax.ext.DeclHandler

---

internalEntityDecl

public void internalEntityDecl(java.lang.String name,
                               java.lang.String value)

Description copied from interface: org.xml.sax.ext.DeclHandler

Report an internal entity declaration.

Only the effective (first) declaration for each entity will be reported. All parameter entities in the value will be expanded, but general entities will not.

Specified by:

internalEntityDecl in interface org.xml.sax.ext.DeclHandler

---

setErrorException

public void setErrorException(java.lang.Exception e)
