Member Function Documentation

Clone()

virtual CQFilter* CQFHasField::Clone ( )

inlinevirtual

clone this filter

Reimplemented from CQFSort.

Reimplemented in CQFHasFieldSet, CQFHasFieldInfix, CQFHasFieldSuffix, CQFHasFieldPrefix, CQFHasFieldRegex, and CQFHasFieldValue.

References CQFilter::Compile(), and CQFilter::toString().

Here is the call graph for this function:

Negate()

void CQFHasField::Negate ( void  )

virtual

negate the filter condition

Compile()

bool CQFHasField::Compile ( CQueryCompiler *  compiler, CQueryOptions *  options  )

virtual

compile the filter. requires reference to underlying CConcIndexator. CQFHasField implementation just ensures that m_arg0, m_arg1 are non-empty, throwing a CExpc otherwise

Reimplemented from CQFSort.

virtual

generic stringification; uses valueString()

Reimplemented from CQFSort.
