◆ GetArchitectureAtIndex()

bool ObjectContainerUniversalMachO::GetArchitectureAtIndex	(	uint32_t	idx,
		lldb_private::ArchSpec &	arch
	)		const

overridevirtual

Gets the architecture given an index.

Copies the architecture specification for index idx.

Parameters

[in]	idx	The architecture index to extract.
[out]	arch	A architecture object that will be filled in if idx is a architecture valid index.

Returns: Returns true if idx is valid and arch has been filled in, false otherwise.

◆ GetNumArchitectures()

size_t ObjectContainerUniversalMachO::GetNumArchitectures ( ) const

overridevirtual

Get the number of architectures in this object file.

The default implementation returns 1 as for object files that contain a single architecture. ObjectContainer instances that contain more than one architecture should override this function and return an appropriate value.

Returns: The number of architectures contained in this object file.

Reimplemented from lldb_private::ObjectContainer.

References m_header.

◆ GetObjectFile()

ObjectFileSP ObjectContainerUniversalMachO::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 in 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 ObjectContainerUniversalMachO::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.
