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.

Method Detail

getGrammarType

public java.lang.String getGrammarType()

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

Specified by:

getGrammarType in interface org.apache.xerces.xni.grammars.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 org.apache.xerces.xni.grammars.XMLSchemaDescription

Returns:

the value indicating the context

getTargetNamespace

public java.lang.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 org.apache.xerces.xni.grammars.XMLSchemaDescription

Returns:

the expected/enclosing target namespace

getLocationHints

public java.lang.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 org.apache.xerces.xni.grammars.XMLSchemaDescription

Returns:

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

getTriggeringComponent

public org.apache.xerces.xni.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 org.apache.xerces.xni.grammars.XMLSchemaDescription

Returns:

the name of the triggering component

getEnclosingElementName

public org.apache.xerces.xni.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 org.apache.xerces.xni.grammars.XMLSchemaDescription

Returns:

the name of the enclosing element

getAttributes

public org.apache.xerces.xni.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).
