Constant Field Values

CONTEXT_REDEFINE

public static final short CONTEXT_REDEFINE

Constant Field Values

CONTEXT_IMPORT

public static final short CONTEXT_IMPORT

Indicate that the current schema document is ed by another schema document.

See Also:

Constant Field Values

CONTEXT_PREPARSE

public static final short CONTEXT_PREPARSE

Indicate that the current schema document is being preparsed.

See Also:

Constant Field Values

CONTEXT_INSTANCE

public static final short CONTEXT_INSTANCE

Indicate that the parse of the current schema document is triggered by xsi:schemaLocation/noNamespaceSchemaLocation attribute(s) in the instance document. This value is only used if we don't defer the loading of schema documents.

See Also:

Constant Field Values

CONTEXT_ELEMENT

public static final short CONTEXT_ELEMENT

Indicate that the parse of the current schema document is triggered by the occurrence of an element whose namespace is the target namespace of this schema document. This value is only used if we do defer the loading of schema documents until a component from that namespace is referenced from the instance.

See Also:

Constant Field Values

CONTEXT_ATTRIBUTE

public static final short CONTEXT_ATTRIBUTE

Indicate that the parse of the current schema document is triggered by the occurrence of an attribute whose namespace is the target namespace of this schema document. This value is only used if we do defer the loading of schema documents until a component from that namespace is referenced from the instance.

See Also:

Constant Field Values

CONTEXT_XSITYPE

public static final short CONTEXT_XSITYPE

Indicate that the parse of the current schema document is triggered by the occurrence of an "xsi:type" attribute, whose value (a QName) has the target namespace of this schema document as its namespace. This value is only used if we do defer the loading of schema documents until a component from that namespace is referenced from the instance.

Constructor Detail

XSDDescription

public XSDDescription()

Method Detail

getGrammarType

public String getGrammarType()

the type of the grammar (e.g., DTD or XSD);

Specified by:

getGrammarType in interface XMLGrammarDescription

Returns:

the type of this grammar

See Also:

Grammar

getContextType

public short getContextType()

Get the context. The returned value is one of the pre-defined CONTEXT_xxx constants.

Specified by:

getContextType in interface XMLSchemaDescription

Returns:

the value indicating the context

getTargetNamespace

public String getTargetNamespace()

If the context is "include" or "redefine", then return the target namespace of the enclosing schema document; otherwise, the expected target namespace of this document.

Specified by:

getTargetNamespace in interface XMLSchemaDescription

Returns:

the expected/enclosing target namespace

getLocationHints

public String[] getLocationHints()

For import and references from the instance document, it's possible to have multiple hints for one namespace. So this method returns an array, which contains all location hints.

Specified by:

getLocationHints in interface XMLSchemaDescription

Returns:

an array of all location hints associated to the expected target namespace

getTriggeringComponent

public QName getTriggeringComponent()

If a call is triggered by an element/attribute/xsi:type in the instance, this call returns the name of such triggering component: the name of the element/attribute, or the value of the xsi:type.

Specified by:

getTriggeringComponent in interface XMLSchemaDescription

Returns:

the name of the triggering component

getEnclosingElementName

public QName getEnclosingElementName()

If a call is triggered by an attribute or xsi:type, then this mehtod returns the enclosing element of such element.

Specified by:

getEnclosingElementName in interface XMLSchemaDescription

Returns:

the name of the enclosing element

getAttributes

public XMLAttributes getAttributes()

If a call is triggered by an element/attribute/xsi:type in the instance, this call returns all attribute of such element (or enclosing element).

Specified by:

getAttributes in interface XMLSchemaDescription

Returns:

all attributes of the tiggering/enclosing element

fromInstance

public boolean fromInstance()

equals

public boolean equals(Object descObj)

Compares this grammar with the given grammar. Currently, we compare the target namespaces.

Returns:

True if they are equal, else false

Returns the hash code of this grammar

Overrides:

hashCode in class XMLResourceIdentifierImpl

Returns:

The hash code
