Detailed Description

template<typename ValueType, typename SizeType = ValueType>
class crashpad::CheckedRange< ValueType, SizeType >

Ensures that a range, composed of a base and size, does not overflow its data type.

Member Function Documentation

ContainsRange()

template<typename ValueType , typename SizeType = ValueType>

bool crashpad::CheckedRange< ValueType, SizeType >::ContainsRange ( const CheckedRange< ValueType, SizeType > &  that ) const

inline

Returns whether the range contains another range.

Parameters

[in]

that

The (possibly) contained range.

Returns

true if this range, the containing range, contains that, the contained range. false otherwise.

A range contains another range when the contained range’s base is greater than or equal to the containing range’s base, and the contained range’s end is less than or equal to the containing range’s end.

This method must only be called if IsValid() would return true for both CheckedRange objects involved.

ContainsValue()

template<typename ValueType , typename SizeType = ValueType>

bool crashpad::CheckedRange< ValueType, SizeType >::ContainsValue ( ValueType  value ) const

inline

Returns whether the range contains another value.

Parameters

[in]

value

The (possibly) contained value.

Returns

true if the range contains value, false otherwise.

A range contains a value if the value is greater than or equal to its base, and less than its end (base plus size).

This method must only be called if IsValid() would return true.

IsValid()

template<typename ValueType , typename SizeType = ValueType>

bool crashpad::CheckedRange< ValueType, SizeType >::IsValid ( ) const

inline

Returns the validity of the range.

Returns

true if the range is valid, false otherwise.

A range is valid if its size can be converted to the range’s data type without data loss, and if its end (base plus size) can be computed without overflowing its data type.

OverlapsRange()

template<typename ValueType , typename SizeType = ValueType>

bool crashpad::CheckedRange< ValueType, SizeType >::OverlapsRange ( const CheckedRange< ValueType, SizeType > &  that ) const

inline

Returns whether the range overlaps another range.

Parameters

[in]

that

The (possibly) overlapping range.

Returns

true if this range, the first range, overlaps that, the provided range. false otherwise.

Ranges are considered to be closed-open [base, end) for this test. Zero length ranges are never considered to overlap another range.

This method must only be called if IsValid() would return true for both CheckedRange objects involved.
