Detailed Description

The writer for a MinidumpCrashpadInfo stream in a minidump file.

Member Function Documentation

◆ Children()

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

Returns the object’s children.

Note
Valid in kStateFrozen or any subsequent state.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ Freeze()

bool crashpad::MinidumpCrashpadInfoWriter::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::MinidumpCrashpadInfoWriter::InitializeFromSnapshot ( const ProcessSnapshot process_snapshot)

Initializes MinidumpCrashpadInfo based on process_snapshot.

This method may add additional structures to the minidump file as children of the MinidumpCrashpadInfo stream. To do so, it may obtain other snapshot information from process_snapshot, such as a list of ModuleSnapshot objects used to initialize MinidumpCrashpadInfo::module_list. Only data that is considered useful will be included. For module information, usefulness is determined by MinidumpModuleCrashpadInfoListWriter::IsUseful().

Parameters
[in]process_snapshotThe process snapshot to use as source data.
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.

◆ IsUseful()

bool crashpad::MinidumpCrashpadInfoWriter::IsUseful ( ) const

Determines whether the object is useful.

A useful object is one that carries data that makes a meaningful contribution to a minidump file. An object carrying children would be considered useful.

Returns
true if the object is useful, false otherwise.

◆ SetModuleList()

void crashpad::MinidumpCrashpadInfoWriter::SetModuleList ( std::unique_ptr< MinidumpModuleCrashpadInfoListWriter module_list)

Arranges for MinidumpCrashpadInfo::module_list to point to the MinidumpModuleCrashpadInfoList object to be written by module_list.

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

Note
Valid in kStateMutable.

◆ SetSimpleAnnotations()

void crashpad::MinidumpCrashpadInfoWriter::SetSimpleAnnotations ( std::unique_ptr< MinidumpSimpleStringDictionaryWriter simple_annotations)

Arranges for MinidumpCrashpadInfo::simple_annotations to point to the MinidumpSimpleStringDictionaryWriter object to be written by simple_annotations.

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

Note
Valid in kStateMutable.

◆ SizeOfObject()

size_t crashpad::MinidumpCrashpadInfoWriter::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::MinidumpCrashpadInfoWriter::StreamType ( ) const
overrideprotectedvirtual

Returns an object’s stream type.

Note
Valid in any state.

Implements crashpad::internal::MinidumpStreamWriter.

◆ WriteObject()

bool crashpad::MinidumpCrashpadInfoWriter::WriteObject ( FileWriterInterface file_writer)
overrideprotectedvirtual

Writes the object’s content.

Parameters
[in]file_writerThe 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.
