Detailed Description

A test MemorySnapshot that can carry arbitrary data for testing purposes.

Member Function Documentation

MergeWithOtherSnapshot()

const MemorySnapshot * crashpad::test::TestMemorySnapshot::MergeWithOtherSnapshot ( const MemorySnapshot *  other ) const

overridevirtual

Creates a new MemorySnapshot based on merging this one with other.

The ranges described by the two snapshots must either overlap or abut, and must be of the same concrete type.

Returns

A newly allocated MemorySnapshot representing the merged range, or nullptr with an error logged.

Implements crashpad::MemorySnapshot.

Read()

bool crashpad::test::TestMemorySnapshot::Read ( Delegate *  delegate ) const

overridevirtual

Calls Delegate::MemorySnapshotDelegateRead(), providing it with the memory snapshot’s data.

Implementations do not necessarily read the memory snapshot data prior to this method being called. Memory snapshot data may be loaded lazily and may be discarded after being passed to the delegate. This provides clean memory management without burdening a snapshot implementation with the requirement that it track all memory region data simultaneously.

Returns

false on failure, otherwise, the return value of Delegate::MemorySnapshotDelegateRead(), which should be true on success and false on failure.

Implements crashpad::MemorySnapshot.

SetValue()

void crashpad::test::TestMemorySnapshot::SetValue ( char  value )

inline

Sets the value to fill the test memory region with.

Parameters

[in]

value

The value to be written to delegate when Read() is called. This value will be repeated Size() times.
