Method Detail

index

void index(java.util.Set<java.io.File> files,
         java.io.OutputStream out,
         java.util.Map<java.lang.String,java.lang.String> config)
           throws java.lang.Exception

Index a set of input files and write the Repository XML representation to the stream

Parameters:

files - a set of input files

out - the stream to write the XML representation to

config - a set of optional parameters (use the interface constants as keys)

Throws:

java.lang.Exception - in case of an error

indexFragment

void indexFragment(java.util.Set<java.io.File> files,
                 java.io.Writer out,
                 java.util.Map<java.lang.String,java.lang.String> config)
                   throws java.lang.Exception

Index a set of input files and write a Repository XML fragment to the given writer.

Note that the result will be one or more XML resource elements without a top-level surrounding repository element. The resulting XML is therefore not well-formed.

This method may be useful for repository managers that wish to (re-)index individual resources and assemble the XML fragments into a complete repository document later.

Parameters:

files - a set of input files

out - the writer to write the Repository XML representation to

config - a set of optional parameter (use the interface constants as keys)

Throws:

java.lang.Exception - in case of an error
