Method Detail

getDownScaler

Returns the image downscaler to use when writing an image resource to the given root path.

If null is returned, image downscaling must not be used for the resource with the given path.

Returns:

the downscaler to use, or null if no downscaling is required for the resource

Returns the static type id of this (default) resource type.

Returns:

the static type id of this (default) resource type

getStaticTypeName

public static java.lang.String getStaticTypeName()

Returns the static type name of this (default) resource type.

Returns:

the static type name of this (default) resource type

Overrides:

importResource in class A_CmsResourceType

Parameters:

cms - the initialized CmsObject

securityManager - the initialized OpenCms security manager

resourcename - the target name (with full path) for the resource after import

resource - the resource to be imported

content - the content of the resource

properties - the properties of the resource

Returns:

the imported resource

Throws:

CmsException - if something goes wrong

                       throws CmsConfigurationException

Description copied from interface: I_CmsResourceType

Special version of the configuration initialization used with resource types to set resource type, id and class name, required for the XML configuration.

Please note: Many resource types defined in the core have in fact a fixed resource type and a fixed id. Configurable name and id is used only for certain types.

The provided named class must implement this interface (I_CmsResourceType). Usually the provided class name should be the class name of the resource type instance, but this may be different in special cases or configuration errors. For example, if a module is imported that contains it's own resource type class files, the included class file are usually not be available until the server is restarted. If the named class given in the XML configuration (or module manifest.xml) is not available, or not implementing I_CmsResourceType, then CmsResourceTypeUnknown is used for the resource type instance.

Specified by:

initConfiguration in interface I_CmsResourceType

Overrides:

initConfiguration in class A_CmsResourceType

Parameters:

name - the resource type name

id - the resource type id

className - the class name of the resource type (read from the XML configuration)

Throws:

CmsConfigurationException - if the configuration is invalid

A_CmsResourceType.initConfiguration(java.lang.String, java.lang.String, String)
