Detailed Description

Represents an Entity constructed from a VariableSP.

This class is used for materialization of variables for which the user does not have a VariableSP available (e.g., when materializing ivars).

Member Function Documentation

GetByteSize()

std::optional< uint64_t > EntityValueObject::GetByteSize ( ExecutionContextScope *  scope ) const

inlineoverridevirtual

Returns size in bytes of the type associated with this variable.

Returns

On success, returns byte size of the type associated with this variable. Returns std::nullopt otherwise.

Implements EntityVariableBase.

Definition at line 863 of file Materializer.cpp.

GetName()

ConstString EntityValueObject::GetName ( ) const

inlineoverridevirtual

Implements EntityVariableBase.

Definition at line 850 of file Materializer.cpp.

GetTypeBitAlign()

std::optional< size_t > EntityValueObject::GetTypeBitAlign ( ExecutionContextScope *  scope ) const

inlineoverridevirtual

Returns alignment of the type associated with this variable in bits.

Returns

On success, returns alignment in bits for the type associated with this variable. Returns std::nullopt otherwise.

Implements EntityVariableBase.

Definition at line 878 of file Materializer.cpp.

LocationExpressionIsValid()

bool EntityValueObject::LocationExpressionIsValid ( ) const

inlineoverridevirtual

Returns 'true' if the location expression associated with this variable is valid.

Implements EntityVariableBase.

Definition at line 870 of file Materializer.cpp.

SetupValueObject()

lldb::ValueObjectSP EntityValueObject::SetupValueObject ( ExecutionContextScope *  scope )

inlineoverridevirtual

Creates and returns ValueObject tied to this variable and prepares Entity for materialization.

Called each time the Materializer (de)materializes a variable. We re-create the ValueObject based on the current ExecutionContextScope since clients such as conditional breakpoints may materialize the same EntityVariable multiple times with different frames.

Each subsequent use of the EntityVariableBase interface will query the newly created ValueObject until this function is called again.

Implements EntityVariableBase.
