                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

setGrailsApplication

registerTagLibraries

protected void registerTagLibraries()

registerTemplateNamespace

protected void registerTemplateNamespace()

registerTagLib

public void registerTagLib(org.codehaus.groovy.grails.commons.GrailsTagLibClass taglib)

Registers a tag library for lookup. Each of the tags in the library is mapped by namespace:name to the taglib bean. If the taglib has already been registered, this method will override the existing information and update the tags to use the new version.

Parameters:

taglib - The taglib descriptor class.

putTagLib

protected void putTagLib(java.util.Map<java.lang.String,java.lang.Object> tags,
                         java.lang.String name,
                         org.codehaus.groovy.grails.commons.GrailsTagLibClass taglib)

lookupTagLibrary

public groovy.lang.GroovyObject lookupTagLibrary(java.lang.String namespace,
                                                 java.lang.String tagName)

Looks up a tag library for the given namespace and tag name.

Parameters:

namespace - The tag library namespace

tagName - The tag name

Returns:

The tag library or null if it wasn't found

doesTagReturnObject

public boolean doesTagReturnObject(java.lang.String namespace,
                                   java.lang.String tagName)

lookupNamespaceDispatcher

public org.codehaus.groovy.grails.web.taglib.NamespacedTagDispatcher lookupNamespaceDispatcher(java.lang.String namespace)

Looks up a namespace dispatcher for the given namespace

Parameters:

namespace - The namespace

Returns:

The NamespacedTagDispatcher

hasNamespace

public boolean hasNamespace(java.lang.String namespace)

Returns whether the given namespace is in use

Parameters:

namespace - The namespace

Returns:

True if it is in use

getAvailableNamespaces

public java.util.Set<java.lang.String> getAvailableNamespaces()

Returns:

The namespaces available
