c.flexseq: Concatenate Sequences

In Immutables: Fast and Functional Data Structures

Concatenate Sequences

Description

Concatenate Sequences

Usage

## S3 method for class 'flexseq'
c(..., recursive = FALSE)

Arguments

...	flexseq objects.
recursive	Unused; must be FALSE.

Details

c() is supported for flexseq and returns a new concatenated flexseq.

For priority_queue, ordered_sequence, and interval_index, c() is not supported because concatenation can violate structure-specific invariants. Cast first with as_flexseq() when sequence-style concatenation is intended, noting that this drops ordering and priority metadata.

Value

A concatenated flexseq.

Examples

x <- flexseq("a", "b")
y <- flexseq("c", "d")
c(x, y)

q1 <- priority_queue("a", priorities = 2)
q2 <- priority_queue("b", priorities = 1)
try(c(q1, q2))
c(as_flexseq(q1), as_flexseq(q2))

o1 <- ordered_sequence("a", keys = 1)
o2 <- ordered_sequence("b", keys = 2)
try(c(o1, o2))
