Member Function Documentation

AddConstituent()

void WatchpointResource::AddConstituent

(

const lldb::WatchpointSP &

constituent

)

The "Constituents" are the watchpoints that share this resource.

The method adds the constituent to this resource's constituent list.

Parameters

[in]

constituent

constituent is the Wachpoint to add.

BumpHitCounts()

void lldb_private::WatchpointResource::BumpHitCounts ( )

protected

Constituents()

WatchpointIterable lldb_private::WatchpointResource::Constituents ( )

inline

Iterate over the watchpoint constituents for this resource.

Returns

An Iterable object which can be used to loop over the watchpoints that are constituents of this resource.

References m_constituents, and m_constituents_mutex.

ConstituentsContains() [1/2]

bool WatchpointResource::ConstituentsContains

(

const lldb::WatchpointSP &

wp_sp

)

Check if the constituents includes a watchpoint.

Parameters

[in]

wp_sp

The WatchpointSP to search for.

Returns

true if this resource's constituents includes the watchpoint.

ConstituentsContains() [2/2]

bool WatchpointResource::ConstituentsContains

(

const lldb_private::Watchpoint *

wp

)

Check if the constituents includes a watchpoint.

Parameters

[in]

wp

The Watchpoint to search for.

Returns

true if this resource's constituents includes the watchpoint.

CopyConstituentsList()

WatchpointResource::WatchpointCollection WatchpointResource::CopyConstituentsList

(

)

This method copies the watchpoint resource's constituents into a new collection.

It does this while the constituents mutex is locked.

Returns

A copy of the Watchpoints which own this resource.

This method returns the Watchpoint at index index using this Resource.

The constituents are listed ordinally from 0 to GetNumberOfConstituents() - 1 so you can use this method to iterate over the constituents.

Parameters

[in]

idx

The index in the list of constituents for which you wish the constituent location.

Returns

The Watchpoint at that index.
