◆ GetNumObjects()

size_t lldb_private::ObjectContainerMachOFileset::GetNumObjects ( ) const

inlineoverridevirtual

Get the number of objects within this object file (archives).

Returns: Zero for object files that are not archives, or the number of objects contained in the archive.

Reimplemented from lldb_private::ObjectContainer.

Definition at line 65 of file ObjectContainerMachOFileset.h.

References m_entries.

◆ GetObjectFile()

ObjectFileSP ObjectContainerMachOFileset::GetObjectFile ( const lldb_private::FileSpec * file )

overridevirtual

Selects an architecture in an object file.

Object files that contain a single architecture should verify that the specified arch matches the architecture in the object file and return true or false accordingly.

Object files that contain more than one architecture should attempt to select that architecture, and if successful, clear out any previous state from any previously selected architecture and prepare to return information for the new architecture.

Returns: Returns a pointer to the object file of the requested arch and optional name. Returns nullptr of no such object file exists in the container.

◆ ParseHeader() [1/2]

bool ObjectContainerMachOFileset::ParseHeader ( )

overridevirtual

Attempts to parse the object header.

This function is used as a test to see if a given plug-in instance can parse the header data already contained in ObjectContainer::m_data. If an object file parser does not recognize that magic bytes in a header, false should be returned and the next plug-in can attempt to parse an object file.

Returns: Returns true if the header was parsed successfully, false otherwise.
