isAbstract

public boolean isAbstract()

Description copied from interface: ComplexType

Returns true when the complexType should be considered abstract, as defined by the XML schema of which this complex type definition is a part.

Specified by:

isAbstract in interface ComplexType

See Also:

ComplexType.isAbstract()

getChild

public ElementGrouping getChild()

Description copied from interface: ComplexType

Returns the child element representing the structure of nested child nodes (if any are allowed).

Specified by:

getChild in interface ComplexType

See Also:

ComplexType.getChild()

getChildElements

public Element[] getChildElements()

Specified by:

getChildElements in interface ComplexType

See Also:

ComplexType.getChildElements()

getValue

public Object getValue(Element element,
                       ElementValue[] value,
                       Attributes attrs,
                       Map hints)
                throws SAXException

Description copied from interface: Type

This method is intended to receive the child elements in the form of ElementValues (@see ElementValue). Recall that this is a pairing containing a reference to the type and the actual value (do not call .getValue on the types). This should return the real value (interpreted value) for this element based on it's children. Remember, this is a XML is a tree structure, so if you don't include some children, they are gone forever (so be careful when ignoring data).

If the element had #CData (Nested Child Text), this will appear in the first slot, with a null Element.

A SAXNotSupportedException should be thrown when the child's [inherited, default implementation of getValue(ElementValue[],Attributes)] method should be used.

Specified by:

getValue in interface Type

Returns:

Object

Throws:

SAXException

See Also:

Type.getValue(org.geotools.xml.schema.Element, org.geotools.xml.schema.ElementValue[], org.xml.sax.Attributes, java.util.Map)

getName

public String getName()

Description copied from interface: Type

This returns the XML Schema declaration name of this type (both complex and simple types have names ...)

Specified by:

getName in interface Type

See Also:

Type.getName()

getInstanceType

public Class getInstanceType()

Description copied from interface: Type

This will return the intended Java Class for this element type. For generic complex types this will be an object array. SimpleTypes will match as they are parsed, and custom extensions will also return the appropriate class value.

Specified by:

getInstanceType in interface Type

See Also:

Type.getInstanceType()

canEncode

public boolean canEncode(Element element,
                         Object value,
                         Map hints)

Subclass must override this method to allow encoding.

Specified by:

canEncode in interface Type

Parameters:

element - The element which may be used to represent the Object. This is included to allow for child definitions to include addition information where appropriate.

value - An Object which may or may not be encodeable by this type. The value may also be null.

Returns:

false, subclass override to allow encoding

See Also:

Type.canEncode(org.geotools.xml.schema.Element, java.lang.Object, java.util.Map)

encode

public void encode(Element element,
                   Object value,
                   PrintHandler output,
                   Map hints)
            throws IOException,
                   OperationNotSupportedException

Subclass should implement this, this implementation provides a good OperationsNotSupportedException.

Specified by:

encode in interface Type

Parameters:

element - The original element declaration to which we should encode.

value - The Object to encode.

output - This is where the output should be written to.

hints - For providing additional context information to specific schemas.

Throws:

IOException - When there is an error with the Writer.

OperationNotSupportedException - When this type cannot be encoded ... and wasn't checked first.

See Also:

Type.encode(org.geotools.xml.schema.Element, java.lang.Object, org.geotools.xml.PrintHandler, java.util.Map)

getParent

public Type getParent()

Description copied from interface: ComplexType

This is used to represent the heirarchy represented within an xml schema document(s). This is particularily useful, as the parent will have the first attempt to create a real (non Object[]) value of the element. For more information see getValue.

Specified by:

getParent in interface ComplexType

See Also:

ComplexType.getParent()

getAnyAttributeNameSpace

public String getAnyAttributeNameSpace()

Description copied from interface: ComplexType

This methos represents the potential 'anyAttribute' declaration's namespace attribute which may occur within a complex type definition.

Specified by:

getAnyAttributeNameSpace in interface ComplexType

See Also:

ComplexType.getAnyAttributeNameSpace()

getAttributes

public Attribute[] getAttributes()

Description copied from interface: ComplexType

The set of attributes required by this complex type declaration. As per the xml schema definition, there is not an implied order to the attributes. For performance reasons an implementor may wich to order the attributes from most common to least commonly used attributes.

Specified by:

getAttributes in interface ComplexType

See Also:

ComplexType.getAttributes()

getBlock

public int getBlock()

Description copied from interface: ComplexType

Specifies a mask which denotes which substitution mechanisms may be used for this complex type definition.

Specified by:

getBlock in interface ComplexType

See Also:

ComplexType.getBlock()

getFinal

public int getFinal()

Description copied from interface: ComplexType

Specifies a mask which denotes which substitution mechanisms prohibited for use by child definitions of this complex type.

Specified by:

getFinal in interface ComplexType

See Also:

ComplexType.getFinal()

getId

Specified by:

getId in interface ComplexType

See Also:

ComplexType.getId()

isMixed

public boolean isMixed()

Returns true if this complexType allows mixed content (Child elements and a String value).

Specified by:

isMixed in interface ComplexType

See Also:

ComplexType.isMixed()

isDerived

public boolean isDerived()

Description copied from interface: ComplexType

This method is used to publish whether this complexType is at the root of an inheritance tree, or a leaf within an inheritance tree. This method should return true when the complexType is not a root of an inheritance tree.

Specified by:

isDerived in interface ComplexType

See Also:

ComplexType.isDerived()

cache

public boolean cache(Element element,
                     Map hints)

Description copied from interface: ComplexType

This method is a directive to the parser whether to keep the data around in memory for post processing. Generally this should return True, except when streaming.

Specified by:

cache in interface ComplexType

True, except when streaming the element.
