Example usage for com.google.common.collect Lists newArrayListWithExpectedSize

Introduction

In this page you can find the example usage for com.google.common.collect Lists newArrayListWithExpectedSize.

Prototype

@GwtCompatible(serializable = true)
public static <E> ArrayList<E> newArrayListWithExpectedSize(int estimatedSize) 

Source Link

Document

Creates an ArrayList instance to hold estimatedSize elements, plus an unspecified amount of padding; you almost certainly mean to call #newArrayListWithCapacity (see that method for further advice on usage).

Usage

From source file:com.google.gxp.compiler.dot.DotWriter.java

public void recordNode(String nodeId, Map<String, String> properties) {
    List<String> names = Lists.newArrayListWithExpectedSize(properties.size());
    List<String> values = Lists.newArrayListWithExpectedSize(properties.size());
    for (Map.Entry<String, String> entry : properties.entrySet()) {
        names.add(dotEscape(entry.getKey()));
        values.add(dotEscape(entry.getValue()));
    }//from   w  ww. j  av a 2  s.  c o  m
    out.appendLine(String.format("node%s [label=\"{%s} | {%s}\",shape=Mrecord];", nodeId,
            Joiner.on(" | ").join(names), Joiner.on(" | ").join(values)));
