public final Class IntArrayReverseBuilder

extends Reverse
Class Inheritance
Imports
java.util.Arrays
An elastic buffer of integer values, somewhat like the java.lang.StringBuilder, but for arrays of integers. The client prepends data, so the array builds right to left, and may finally take the built array, often without copying the data.

Method Detail

protected void ensure(int n)

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

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

Ensure there is room for another n elements. In general, this will mean allocating new storage (of a carefully-chosen size ≥ n+length()) and copying the existing contents to it.

Parameters
n:int

to make additional space for

Returns:int

the number of elements currently.

Returns:int

The maximum int stored.

protected void prependUnchecked(int v)

Implements abstract org.python.core.stringlib.AbstractIntArrayBuilder.Reverse.prependUnchecked.

Doc from org.python.core.stringlib.AbstractIntArrayBuilder.Reverse.prependUnchecked.

Prepend 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 prepend

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[]

the elements in the buffer
