Class ProcessIfTagHandler
java.lang.Object
org.xml.sax.helpers.DefaultHandler
org.jasig.portal.car.ProcessIfTagHandler
- All Implemented Interfaces:
- org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler
- public class ProcessIfTagHandler
- extends org.xml.sax.helpers.DefaultHandler
Handles a "processIf" tag looking for the following attributes and
blocking SAX events from reaching nested tags if the specified
requirements are not met.
fname = the functional name whose version is to be checked
version = value is one of lessThan, greaterThan, lessThanOrEqual,
greaterThanOrEqual, equalTo, or notEqualTo.
major = the revision level major part
minor = the revision level minor part
micro = the revision level micro part
setMajor = optional, the new revision level major part
setMinor = optional, the new revision level minor part
setMicro = optional, the new revision level micro part
The contents of the processIf tag are only processed if the version
of the specified fname matches the requirements as specified in the
version, major, minor, and micro attributes. If the setMajor,
setMinor, and setMicro attributes are specified then and additional
test is performed to determine if processing will occur. This test
involves attempting to set the version of the fname to that
specified. If unable to then processing will be skipped for this
block. This is done to allow the same CAR to be deployed on all
servers in a multi-server deployment but only have on of the
servers perform the processing of the block and affect the
database.
There is no limit on the number of processIf blocks that can occur
in a deployment descriptor. All other nested tags are supported
within the processIf tag. The processIf tag can not be nested
inside of itself.
