Field Summary
`static 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.
`static 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.
`static short` | `CONTEXT_IMPORT` Indicate that the current schema document is <import>ed by another schema document.
`static short` | `CONTEXT_INCLUDE` Indicate that the current schema document is <include>d by another schema document.
`static short` | `CONTEXT_INSTANCE` Indicate that the parse of the current schema document is triggered by xsi:schemaLocation/noNamespaceSchemaLocation attribute(s) in the instance document.
`static short` | `CONTEXT_PREPARSE` Indicate that the current schema document is being preparsed.
`static short` | `CONTEXT_REDEFINE` Indicate that the current schema document is <redefine>d by another schema document.
`static 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.

Method Summary
`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).
`short` | `getContextType()` Get the context.
`QName` | `getEnclosingElementName()` If a call is triggered by an attribute or xsi:type, then this mehtod returns the enclosing element of such element.
`java.lang.String[]` | `getLocationHints()` For import and references from the instance document, it's possible to have multiple hints for one namespace.
`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.
`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.

Field Detail

### CONTEXT_INCLUDE

    public static final short CONTEXT_INCLUDE

  Indicate that the current schema document is <include>d by another schema document.

### CONTEXT_REDEFINE

    public static final short CONTEXT_REDEFINE

  Indicate that the current schema document is <redefine>d by another schema document.

### CONTEXT_IMPORT

    public static final short CONTEXT_IMPORT

  Indicate that the current schema document is <import>ed by another schema document.

### CONTEXT_PREPARSE

    public static final short CONTEXT_PREPARSE

  Indicate that the current schema document is being preparsed.

### 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.

### 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.

### 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.

### 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

### getContextType

    public short getContextType()

  Get the context. The returned value is one of the pre-defined CONTEXT_xxx constants.
  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.
  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.
  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.
  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.
  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).
  Returns:
    all attributes of the tiggering/enclosing element
