Member Function Documentation

◆ data()

const std::vector<uint8_t>& crashpad::MinidumpByteArrayWriter::data ( ) const
inline

Gets the data to be written.

Note
Valid in any state.

◆ Freeze()

bool crashpad::MinidumpByteArrayWriter::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.

◆ set_data() [1/2]

void crashpad::MinidumpByteArrayWriter::set_data ( const std::vector< uint8_t > &  data)
inline

Sets the data to be written.

Note
Valid in kStateMutable.

◆ set_data() [2/2]

void crashpad::MinidumpByteArrayWriter::set_data ( const uint8_t *  data,
size_t  size 
)

Sets the data to be written.

Note
Valid in kStateMutable.

◆ SizeOfObject()

size_t crashpad::MinidumpByteArrayWriter::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.

◆ WriteObject()

bool crashpad::MinidumpByteArrayWriter::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.
