Field details

P bool isReadOnlyBase The underlying field of the ReadOnly property
P System.Collections.Generic.IEqualityComparer<T> itemequalityComparer The item equalityComparer of the collection
P int size The number of items in the collection
P int stamp The current stamp value

Property details

int CountAccess: Read-Only

Value:The size of this collection

Speed CountSpeedAccess: Read-Only

Value:A characterization of the speed of the Count property in this collection.

The value is symbolic indicating the type of asymptotic complexity in terms of the size of this collection (worst-case or amortized as relevant).
System.Collections.Generic.IEqualityComparer<T> EqualityComparerAccess: Read-Only

Value:

bool IsEmptyAccess: Read-Only

Value:True if this collection is empty

bool IsReadOnlyAccess: Read-Only

Value:True if this collection is read only

Constructor details

PCollectionBase<T>(System.Collections.Generic.IEqualityComparer<T> itemequalityComparer)
Parameters:
itemequalityComparer:

Method details

NP void checkRange(int start, int count) Utility method for range checking.
Throws
System.ArgumentOutOfRangeException if the start or count is negative or if the range does not fit within collection size.
Parameters:
start:start of range
count:size of range
S int ComputeHashCode(ICollectionValue<T> items, System.Collections.Generic.IEqualityComparer<T> itemequalityComparer) Compute the unsequenced hash code of a collection
Returns:The hash code
Parameters:
items:The collection to compute hash code for
itemequalityComparer:The item equalityComparer
A System.Collections.Generic.IEnumerator<T> GetEnumerator() Create an enumerator for this collection.
Returns:The enumerator
int GetUnsequencedHashCode() Get the unsequenced collection hash code of this collection: from the cached value if present and up to date, else (re)compute.
Returns:The hash code
P void modifycheck(int thestamp) Check if the collection has been modified since a specified time, expressed as a stamp value.
Throws
CollectionModifiedException if this collection has been updated since a target time
Parameters:
thestamp:The stamp identifying the target time
S bool StaticEquals(ICollection<T> collection1, ICollection<T> collection2, System.Collections.Generic.IEqualityComparer<T> itemequalityComparer) Examine if collection1 and collection2 are equal as unsequenced collections using the specified item equalityComparer (assumed compatible with the two collections).
Returns:True if equal
Parameters:
collection1:The first collection
collection2:The second collection
itemequalityComparer:The item equalityComparer to use for comparison
bool UnsequencedEquals(ICollection<T> otherCollection) Check if the contents of otherCollection is equal to the contents of this in the unsequenced sense. Uses the item equality comparer of this collection
Returns:True if equal
Parameters:
otherCollection:The collection to compare to.
P void updatecheck() Check if it is valid to perform update operations, and if so increment stamp.
Throws
ReadOnlyCollectionExceptionIf colection is read-only
