Detailed Description

template<class ElementType, class TypeOfCriticalSectionToUse>
class juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >

Implements some basic array storage allocation functions.

This class isn't really for public use - it used to be part of the container classes but has since been superseded by ArrayBase. Eventually it will be removed from the API.

Constructor & Destructor Documentation

◆ ArrayAllocationBase()

template<class ElementType , class TypeOfCriticalSectionToUse >

juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::ArrayAllocationBase ( ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse > && other )

noexcept

Member Function Documentation

◆ ensureAllocatedSize()

template<class ElementType , class TypeOfCriticalSectionToUse >

void juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::ensureAllocatedSize ( int minNumElements )

Increases the amount of storage allocated if it is less than a given amount.

This will retain any data currently held in the array, but will add extra space at the end to make sure there it's at least as big as the size passed in. If it's already bigger, no action is taken.

Parameters

minNumElements the minimum number of elements that are needed

Definition at line 89 of file juce_ArrayAllocationBase.h.

◆ operator=()

template<class ElementType , class TypeOfCriticalSectionToUse >

ArrayAllocationBase & juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::operator= ( ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse > && other )

noexcept

Definition at line 53 of file juce_ArrayAllocationBase.h.

◆ setAllocatedSize()

template<class ElementType , class TypeOfCriticalSectionToUse >

void juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::setAllocatedSize ( int numElements )

Changes the amount of storage allocated.

This will retain any data currently held in the array, and either add or remove extra space at the end.

Parameters

numElements the number of elements that are needed

Definition at line 68 of file juce_ArrayAllocationBase.h.

◆ shrinkToNoMoreThan()

template<class ElementType , class TypeOfCriticalSectionToUse >

void juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::shrinkToNoMoreThan ( int maxNumElements )

Minimises the amount of storage allocated so that it's no more than the given number of elements.

Definition at line 100 of file juce_ArrayAllocationBase.h.

◆ swapWith()

template<class ElementType , class TypeOfCriticalSectionToUse >

void juce::ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse >::swapWith ( ArrayAllocationBase< ElementType, TypeOfCriticalSectionToUse > & other )
