java.lang.String[]	getNamespaces() Returns the namespaces for this FunctionResolver.
boolean	hasFunction(java.lang.String namespace, java.lang.String name) Returns true if this FunctionResolver has a function with the given name.
XSLTFunction	resolveFunction(java.lang.String namespace, java.lang.String name) Returns the FunctionCall associated with the given name

Method Detail

getNamespaces

public java.lang.String[] getNamespaces()

Returns the namespaces for this FunctionResolver. These are the namespaces which will be used by extension functions (within the XSLT document) that are to be resolved by this FunctionResolver,within the XSLT document.
For Example:

  <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform/" 
                     xmlns:foo="http://my.example.com">
     ...
     <xsl:template match="...">
         ...
         <xsl:value-of select="foo:my-function()">
         ...
     </xsl:template>
     ...
  </xsl:stylesheet>
 

Returns:

an array of namespaces supported by this FunctionResolver

hasFunction

public boolean hasFunction(java.lang.String namespace,
                           java.lang.String name)

Returns true if this FunctionResolver has a function with the given name.

Parameters:

namespace - of the function

name - the name of the function

resolveFunction

public XSLTFunction resolveFunction(java.lang.String namespace,
                                    java.lang.String name)

Returns the FunctionCall associated with the given name

Parameters:

namespace - the namespace of the function

name - the name of the function

Returns:

the FunctionCall or null if no function could be found.
