Constructor Detail

LinkageChecker

public LinkageChecker(ICompilerProject project,
              ITargetSettings targetSettings)

Constructor.

Parameters:

project - The project.

targetSettings - The target settings.

Method Detail

isExternal

public boolean isExternal(ICompilationUnit cu)
                   throws InterruptedException

Test if a compilation is should be included in the target or not.

Parameters:

cu - The compilation unit to test.

Returns:

true if the compilation should be excluded from the target, false otherwise.

Throws:

InterruptedException

initExterns

public void initExterns()
                 throws InterruptedException

Initialize the externs set. Combine the symbols explicitly externed by the user together with the symbols in each of the libraries on the external library path. We use the symbols from external libraries instead of just checking if the compilation unit comes from an external library to fix the case where we would include a symbol like "mx_internal" because it was in both an external library and a "normal" library. With "mx_internal" in the externs table the compilation unit will be excluded no matter which library it is found in. This in being done to match the behavior of the old compiler.

Throws:

InterruptedException - if implementation throws one
