Detailed Description

The writer for a MINIDUMP_EXCEPTION_STREAM stream in a minidump file.

Member Function Documentation

◆ Children()

std::vector< internal::MinidumpWritable * > crashpad::MinidumpExceptionWriter::Children ( )

overrideprotectedvirtual

Returns the object’s children.

Note: Valid in kStateFrozen or any subsequent state.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ Freeze()

bool crashpad::MinidumpExceptionWriter::Freeze ( )

overrideprotectedvirtual

Transitions the object from kStateMutable to kStateFrozen.

The default implementation marks the object as frozen and recursively calls Freeze() on all of its children. Subclasses may override this method to perform processing that should only be done once callers have finished populating an object with data. Typically, a subclass implementation would call RegisterRVA() or RegisterLocationDescriptor() on other objects as appropriate, because at the time Freeze() runs, the in-memory locations of RVAs and location descriptors are known and will not change for the remaining duration of an object’s lifetime.

Returns: true on success. false on failure, with an appropriate message logged.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ InitializeFromSnapshot()

void crashpad::MinidumpExceptionWriter::InitializeFromSnapshot	(	const ExceptionSnapshot *	exception_snapshot,
		const MinidumpThreadIDMap &	thread_id_map
	)

Initializes the MINIDUMP_EXCEPTION_STREAM based on exception_snapshot.

Parameters

[in]	exception_snapshot	The exception snapshot to use as source data.
[in]	thread_id_map	A MinidumpThreadIDMap to be consulted to determine the 32-bit minidump thread ID to use for the thread identified by exception_snapshot.

Note: Valid in kStateMutable. No mutator methods may be called before this method, and it is not normally necessary to call any mutator methods after this method.

◆ SetContext()

void crashpad::MinidumpExceptionWriter::SetContext ( std::unique_ptr< MinidumpContextWriter > context )

Arranges for MINIDUMP_EXCEPTION_STREAM::ThreadContext to point to the CPU context to be written by context.

A context is required in all MINIDUMP_EXCEPTION_STREAM objects.

This object takes ownership of context and becomes its parent in the overall tree of internal::MinidumpWritable objects.

Note: Valid in kStateMutable.

◆ SetExceptionInformation()

void crashpad::MinidumpExceptionWriter::SetExceptionInformation ( const std::vector< uint64_t > & exception_information )

Sets MINIDUMP_EXCEPTION::ExceptionInformation and MINIDUMP_EXCEPTION::NumberParameters.

MINIDUMP_EXCEPTION::NumberParameters is set to the number of elements in exception_information. The elements of MINIDUMP_EXCEPTION::ExceptionInformation are set to the elements of exception_information. Unused elements in MINIDUMP_EXCEPTION::ExceptionInformation are set to 0.

exception_information must have no more than EXCEPTION_MAXIMUM_PARAMETERS elements.

Note: Valid in kStateMutable.

◆ SizeOfObject()

size_t crashpad::MinidumpExceptionWriter::SizeOfObject ( )

overrideprotectedvirtual

Returns the amount of space that this object will consume when written to a minidump file, in bytes, not including any leading or trailing padding necessary to maintain proper alignment.

Note: Valid in kStateFrozen or any subsequent state.

Implements crashpad::internal::MinidumpWritable.

◆ StreamType()

MinidumpStreamType crashpad::MinidumpExceptionWriter::StreamType ( ) const

overrideprotectedvirtual

Returns an object’s stream type.

Note: Valid in any state.

Implements crashpad::internal::MinidumpStreamWriter.

◆ WriteObject()

bool crashpad::MinidumpExceptionWriter::WriteObject ( FileWriterInterface * file_writer )

overrideprotectedvirtual

Writes the object’s content.

Parameters

[in] file_writer The file writer to receive the object’s content.

Returns: true on success. false on error, indicating that the content could not be written to the minidump file.

Note: Valid in kStateWritable. The object will transition to kStateWritten after this method returns.

Implements crashpad::internal::MinidumpWritable.
