Method Detail

getConfig

public org.w3c.dom.DOMConfiguration getConfig()
The configuration of a document. It maintains a table of recognized parameters. Using the configuration, it is possible to change the behavior of the load methods. The configuration may support the setting of and the retrieval of the following non-boolean parameters defined on the DOMConfiguration interface: error-handler (DOMErrorHandler) and resource-resolver (LSResourceResolver).
The following list of boolean parameters is defined:
"validate"
true
[required] (default) Validate an XML Schema during loading. If validation errors are found, the error handler is notified.
false
[optional] Do not report errors during the loading of an XML Schema document.
Specified by:
getConfig in interface org.apache.xerces.xs.XSLoader

loadURIList

public org.apache.xerces.xs.XSModel loadURIList(org.apache.xerces.xs.StringList uriList)
Parses the content of XML Schema documents specified as the list of URI references. If the URI contains a fragment identifier, the behavior is not defined by this specification.
Specified by:
loadURIList in interface org.apache.xerces.xs.XSLoader
Parameters:
uriList - The list of URI locations.
Returns:
An XSModel representing the schema documents.

loadInputList

public org.apache.xerces.xs.XSModel loadInputList(org.apache.xerces.xs.LSInputList is)
Parses the content of XML Schema documents specified as a list of LSInputs.
Specified by:
loadInputList in interface org.apache.xerces.xs.XSLoader
Parameters:
is - The list of LSInputs from which the XML Schema documents are to be read.
Returns:
An XSModel representing the schema documents.

loadURI

public org.apache.xerces.xs.XSModel loadURI(java.lang.String uri)
Parse an XML Schema document from a location identified by a URI reference. If the URI contains a fragment identifier, the behavior is not defined by this specification.
Specified by:
loadURI in interface org.apache.xerces.xs.XSLoader
Parameters:
uri - The location of the XML Schema document to be read.
Returns:
An XSModel representing this schema.

load

public org.apache.xerces.xs.XSModel load(org.w3c.dom.ls.LSInput is)
Parse an XML Schema document from a resource identified by a LSInput .
Specified by:
load in interface org.apache.xerces.xs.XSLoader
Parameters:
is - The LSInput from which the source document is to be read.
Returns:
An XSModel representing this schema.

setParameter

public void setParameter(java.lang.String name,
                         java.lang.Object value)
                  throws org.w3c.dom.DOMException
Description copied from interface: org.w3c.dom.DOMConfiguration
Set the value of a parameter.
Specified by:
setParameter in interface org.w3c.dom.DOMConfiguration
Following copied from interface: org.w3c.dom.DOMConfiguration
Parameters:
name - The name of the parameter to set.
value - The new value or null if the user wishes to unset the parameter. While the type of the value parameter is defined as DOMUserData, the object type must match the type defined by the definition of the parameter. For example, if the parameter is "error-handler", the value must be of type DOMErrorHandler.
Throws:
org.w3c.dom.DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.
NOT_SUPPORTED_ERR: Raised when the parameter name is recognized but the requested value cannot be set.
TYPE_MISMATCH_ERR: Raised if the value type for this parameter name is incompatible with the expected value type.

getParameter

public java.lang.Object getParameter(java.lang.String name)
                              throws org.w3c.dom.DOMException
Description copied from interface: org.w3c.dom.DOMConfiguration
Return the value of a parameter if known.
Specified by:
getParameter in interface org.w3c.dom.DOMConfiguration
Following copied from interface: org.w3c.dom.DOMConfiguration
Parameters:
name - The name of the parameter.
Returns:
The current object associated with the specified parameter or null if no object has been associated or if the parameter is not supported.
Throws:
org.w3c.dom.DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.

canSetParameter

public boolean canSetParameter(java.lang.String name,
                               java.lang.Object value)
Description copied from interface: org.w3c.dom.DOMConfiguration
Check if setting a parameter to a specific value is supported.
Specified by:
canSetParameter in interface org.w3c.dom.DOMConfiguration
Following copied from interface: org.w3c.dom.DOMConfiguration
Parameters:
name - The name of the parameter to check.
value - An object. if null, the returned value is true.
Returns:
true if the parameter could be successfully set to the specified value, or false if the parameter is not recognized or the requested value is not supported. This does not change the current value of the parameter itself.

getParameterNames

public org.w3c.dom.DOMStringList getParameterNames()
Description copied from interface: org.w3c.dom.DOMConfiguration
The list of the parameters supported by this DOMConfiguration object and for which at least one value can be set by the application. Note that this list can also contain parameter names defined outside this specification.
Specified by:
getParameterNames in interface org.w3c.dom.DOMConfiguration
