Return the filter resultant of compiling process

Specified by:

getFilter in interface ICompiler

Returns:

Filter

Throws:

CQLException

See Also:

• ICompiler.compileFilter()

getExpression

public final Expression getExpression()
                               throws CQLException

public List<Filter> getFilterList()
                           throws CQLException

Returns the list of Filters built as the result of calling {@link #FilterListCompilationUnit()()}

Specified by:

getFilterList in interface ICompiler

Returns:

List

Throws:
