Detailed Description

A filter that selects function parameters that are considered optional.

If the underlying function prototype is considered to take variable arguments, the first n parameters (as determined by PrototypePieces.firstVarArgSlot) are considered non-optional. If additional data-types are provided beyond the initial n, these are considered optional. This filter returns true for these optional parameters

Member Function Documentation

clone()

virtual QualifierFilter * ghidra::VarargsFilter::clone ( void  ) const

inlinevirtual

Make a copy of this qualifier.

Returns

the newly allocated copy

Implements ghidra::QualifierFilter.

decode()

void ghidra::VarargsFilter::decode ( Decoder &  decoder )

virtual

Configure details of the criteria being filtered from the given stream.

Parameters

decoder

is the given stream decoder

Reimplemented from ghidra::QualifierFilter.

References ghidra::Decoder::closeElement(), and ghidra::Decoder::openElement().

filter()

bool ghidra::VarargsFilter::filter ( const PrototypePieces &  proto, int4  pos  ) const

virtual

Test whether the given function prototype meets this filter's criteria.

Parameters

proto	is the high-level description of the function prototype to test
pos	is the position of a specific output (pos=-1) or input (pos >=0) in context

Returns

true if the prototype meets the criteria, false otherwise

Implements ghidra::QualifierFilter.
