<internal : Typedef>


Adds a data type definition to the current project. Two attributes are needed, the name that identifies this data type uniquely, and the full name of the class (including the packages) that implements this type.

You can also define a group of data types at once using the file or resource attributes. These attributes point to files in the format of Java property files. Each line defines a single data type in the format:


Typedef should be used to add your own types to the system. Data types are things likepaths or filesets that can be defined at the project level and referenced via their ID attribute.

Custom data types usually need custom tasks to put them to good use.

<classpath> ...

This object represents a path as used by CLASSPATH or PATH environment variable.

    <pathelement location="/path/to/file.jar" />
    <pathelement path="/path/to/file2.jar:/path/to/class2;/path/to/class3" />
    <pathelement location="/path/to/file3.jar" />
    <pathelement location="/path/to/file4.jar" />

The object implemention sometask must provide a method called createSomepath which returns an instance of Path. Nested path definitions are handled by the Path object and must be labeled pathelement.

The path element takes a parameter path which will be parsed and split into single elements. It will usually be used to define a path from an environment variable.

Attribute Description Type Required
refid Makes this instance in effect a reference to another Path instance.

You must not set another attribute or nest elements inside this element if you make it a reference.
