| bool | can_create_synthetic | ||
| ) |
Get a child value by index from a value.
Structs, unions, classes, arrays and pointers have child values that can be access by index.
Structs and unions access child members using a zero based index for each child member. For
Classes reserve the first indexes for base classes that have members (empty base classes are omitted), and all members of the current class will then follow the base classes.
Pointers differ depending on what they point to. If the pointer points to a simple type, the child at index zero is the only child value available, unless synthetic_allowed is true, in which case the pointer will be used as an array and can create 'synthetic' child values using positive or negative indexes. If the pointer points to an aggregate type (an array, class, union, struct), then the pointee is transparently skipped and any children are going to be the indexes of the child values within the aggregate type. For example if we have a 'Point' type and we have a SBValue that contains a pointer to a 'Point' type, then the child at index zero will be the 'x' member, and the child at index 1 will be the 'y' member (the child at index zero won't be a 'Point' instance).
If you actually need an SBValue that represents the type pointed to by a SBValue for which GetType().IsPointeeType() returns true, regardless of the pointee type, you can do that with SBValue::Dereference.
Arrays have a preset number of children that can be accessed by index and will returns invalid child values for indexes that are out of bounds unless the synthetic_allowed is true. In this case the array can create 'synthetic' child values for indexes that aren't in the array bounds using positive or negative indexes.
| [in] | idx | The index of the child value to get |
| [in] | use_dynamic | An enumeration that specifies whether to get dynamic values, and also if the target can be run to figure out the dynamic type of the child value. |
| [in] | can_create_synthetic | If true, then allow child values to be created by index for pointers and arrays for indexes that normally wouldn't be allowed. |

| uint32_t SBValue::GetNumChildren | ( | uint32_t | max | ) |
Return the numer of children of this variable, with a hint that the caller is interested in at most max children.
Use this function to avoid expensive child computations in some cases. For example, if you know you will only ever display 100 elements, calling GetNumChildren(100) can avoid enumerating all the other children. If the returned value is smaller than max, then it represents the true number of children, otherwise it indicates that their number is at least max. Do not assume the returned number will always be less than or equal to max, as the implementation may choose to return a larger (but still smaller than the actual number of children) value.

Get the appropriate ValueObjectSP from this SBValue, consulting the use_dynamic and use_synthetic options passed in to SetSP when the SBValue's contents were set.
Since this often requires examining memory, and maybe even running code, it needs to acquire the Target API and Process StopLock. Those are held in an opaque class ValueLocker which is currently local to SBValue.cpp. So you don't have to get these yourself just default construct a ValueLocker, and pass it into this. If we need to make a ValueLocker and use it in some other .cpp file, we'll have to move it to ValueObject.h/cpp or somewhere else convenient. We haven't needed to so far.
| [in] | value_locker | An object that will hold the Target API, and Process RunLocks, and auto-destroy them when it goes out of scope. Currently this is only useful in SBValue.cpp. |

SBValue::GetError() will be in the success state if this value represents a C++ class with a vtable, or an appropriate error describing that the object isn't a C++ class with a vtable or not a C++ class.
SBValue::GetName() will be the demangled symbol name for the virtual function table like "vtable for <classname>".
SBValue::GetValue() will be the address of the first vtable entry if the current SBValue is a class with a vtable, or nothing the current SBValue is not a C++ class or not a C++ class that has a vtable.
SBValue::GetValueAtUnsigned(...) will return the address of the first vtable entry.
SBValue::GetLoadAddress() will return the address of the vtable pointer found in the parent SBValue.
SBValue::GetNumChildren() will return the number of virtual function pointers in the vtable, or zero on error.
SBValue::GetChildAtIndex(...) will return each virtual function pointer as a SBValue object.
The child SBValue objects will have the following values:
SBValue::GetError() will indicate success if the vtable entry was successfully read from memory, or an error if not.
SBValue::GetName() will be the vtable function index in the form "[%u]" where u is the index.
SBValue::GetValue() will be the virtual function pointer value as a string.
SBValue::GetValueAtUnsigned(...) will return the virtual function pointer value.
SBValue::GetLoadAddress() will return the address of the virtual function pointer.
SBValue::GetNumChildren() returns 0

Find out if a SBValue might have children.
This call is much more efficient than GetNumChildren() as it doesn't need to complete the underlying type. This is designed to be used in a UI environment in order to detect if the disclosure triangle should be displayed or not.
This function returns true for class, union, structure, pointers, references, arrays and more. Again, it does so without doing any expensive type completion.

Watch this value if it resides in memory.
Sets a watchpoint on the value.
