Class "externalVectorWithStorage", external vector class with an external storage for the vector

Description

This is a subclass of "externalVector" that implements the use of arbitrary external backends for storing the elements of the vector.

Objects from the Class

Objects can be created by calls of the form externalVector(type, lengtyh, storageClass).

Slots

storage:

Object of class "externalStorage", the storage backend for the vector elements.

Names:

Object of class "vectorNamesType", names of the elements.

Dim:

Object of class "integerOrNull", dimension of the object.

DimNames:

Object of class "listOrNull", dimnames of the object

Extends

Class "externalVector", directly. Class "vectorNamesType", directly.

Methods

e1 op e2

For any arithmetic or comparison operation op this returns the result of the operation. Either (or both) of e1 and e2 are of class "externalVectorWithSTorage".

Complex(z)

Return the result of an operation in the Complex group generic.

Math(x)

Return the result of an operation in the Math group generic.

Summary(x)

Return the result of an operation in the Summary group generic.

log(x)

Return natural logarithm of x.

log(x, base)

Return logarithm of x with base base.

x[i, j, ..., drop=FALSE]

Extract a subset of x according to the given subscripts.

x[i, j, ...] <- value

Subassign of x by value according to the given subscripts.

as.Rvector(x)

Coerce x to a basic R vector with same names, dimension and dimnames (if any of these are present in x).

asEach(x, type, arrayOnly)

Coerce x so that it now behaves like a basic R vector with the same class as type.

colSums(x, na.rm, dims)

Return the column sums of x.

colMeans(x, na.rm, dims)

Return the column means of x.

rowSums(x, na.rm, dims)

Return the row sums of x.

rowMeans(x, na.rm, dims)

Return the row means of x.

dim(x)

Return the dimension of x.

dim(x) <- value

Set the dimension of x to value.

dimnames(x)

Return the dimnames of x.

getExternalStorage(x)

Return the storage slot of x.

getNativeStorageMethods

Return getNativeStorageMethods(x@storage).

is.finite(x)

Return an external vector of logicals with same length as x indicating if an element of x is finite.

is.infinite(x)

Return an external vector of logicals with same length as x indicating if an element of x is infinite.

is.na(x)

Return an external vector of logicals with same length as x indicating if an element of x is NA.

is.nan(x)

Return an external vector of logicals with same length as x indicating if an element of x is NaN.

length(x)

Return the length of x.

length(x) <- value

Set the length of x to value.

names(x)

Return the names of x.

names(x) <- value

Set the names of x to value.

lapply(X, FUN, ...)

Lapply for "externalVectorWithStorage" class.

setDimNames(x, value)

Set the dimnames of x to value without any error checking or coercion. Return the modified x.

setNames(x, value)

Set the names of x to value without any error checking or coercion. Return the modified x.

rebind(x, length.x = length(x), type = defaultElement(x), names.x = names(x), dim.x = dim(x), dimnames.x = dimnames(x), ..., arrayOnly = FALSE)

Create an "externalVectorWithStorage" object with the same external storage backend class as x but with (possibly) new length, type, names, dim or dimnames. If arrayOnly is FALSE, the names, dim and dimnames for the new object are not set.

initialize(.Object, ...)

Initialize a new object from class "externalVectorWithSTorage".
