public final Class IntArrayBuilder

extends Forward
Class Inheritance
Imports
java.util.Arrays, .Spliterator, java.util.stream.IntStream
An elastic buffer of integer values, somewhat like the java.lang.StringBuilder, but for arrays of integers. The client appends data and may finally take the built array, often without copying the data.

protected void appendUnchecked(int v)

Implements abstract org.python.core.stringlib.AbstractIntArrayBuilder.Forward.appendUnchecked.

Doc from org.python.core.stringlib.AbstractIntArrayBuilder.Forward.appendUnchecked.

Append one element without ensuring that there is space. This method is for use when it is known that there is space for the element, for example, inside a loop before which when ensure(int) has been called.

Parameters
v:int

to append

public int[] take()

Implements abstract org.python.core.stringlib.AbstractIntArrayBuilder.take.

Doc from org.python.core.stringlib.AbstractIntArrayBuilder.take.

Provide the contents as an array and reset the builder to empty. (This is a "destructive read".) The return type is Object in order that sub-classes may define the specific type (for example, int[] or byte[]).

Returns:int[]

the contents as a Python str

Doc from org.python.core.stringlib.AbstractIntArrayBuilder.value.

An array of the elements in the buffer (not modified by methods on this object hereafter).

Returns:int[]
