Constructor & Destructor Documentation

PLearn::InstanceSnippetTest::InstanceSnippetTest ( )

Default constructor.

Definition at line 58 of file InstanceSnippetTest.cc.

{
    // ...

    // ### You may (or not) want to call build_() to finish building the object
    // ### (doing so assumes the parent classes' build_() have been called too
    // ### in the parent classes' constructors, something that you must ensure)
}

void PLearn::InstanceSnippetTest::build ( ) [virtual]

Post-constructor.

The normal implementation should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object.

Reimplemented from PLearn::PTest.

Definition at line 71 of file InstanceSnippetTest.cc.

void PLearn::InstanceSnippetTest::build_ ( ) [private]

This does the actual building.

Reimplemented from PLearn::PTest.

Definition at line 120 of file InstanceSnippetTest.cc.

{
    // ### This method should do the real building of the object,
    // ### according to set 'options', in *any* situation.
    // ### Typical situations include:
    // ###  - Initial building of an object from a few user-specified options
    // ###  - Building of a "reloaded" object: i.e. from the complete set of
    // ###    all serialised options.
    // ###  - Updating or "re-building" of an object after a few "tuning"
    // ###    options have been modified.
    // ### You should assume that the parent class' build_() has already been
    // ### called.

void PLearn::InstanceSnippetTest::declareOptions ( OptionList ol) [static, protected]

Declares the class options.

Reimplemented from PLearn::PTest.

Definition at line 97 of file InstanceSnippetTest.cc.

{
    // ### Declare all of this object's options here.
    // ### For the "flags" of each option, you should typically specify
    // ### one of OptionBase::buildoption, OptionBase::learntoption or
    // ### OptionBase::tuningoption. If you don't provide one of these three,
    // ### this option will be ignored when loading values from a script.
    // ### You can also combine flags, for example with OptionBase::nosave:
    // ### (OptionBase::buildoption | OptionBase::nosave)

    // ### ex:
    // declareOption(ol, "myoption", &InstanceSnippetTest::myoption,
    //               OptionBase::buildoption,
    //               "Help text describing this option");
    // ...

    // Now call the parent class' declareOptions
    inherited::declareOptions(ol);

Transforms a shallow copy into a deep copy.

void PLearn::InstanceSnippetTest::perform ( ) [virtual]

The method performing the test.

A typical test consists in some output (to pout and / or perr), and updates of this object's options.
