Merges two HashMaps.

Groups:

HashMap

Syntax

Syntax:

hashMap1 merge hashMap2

Parameters:

hashMap1: HashMap - this HashMap will be modified

hashMap2: HashMap - all key-value pairs from this HashMap are added to hashMap1. If a key from hashMap2 already exists in hashMap1, it doesn't overwrite the value in hashMap1.

Return Value:

Nothing

Alternative Syntax

Syntax:

hashMap1 merge [hashMap2, overwriteExisting]

Parameters:

hashMap1: HashMap - this HashMap will be modified

hashMap2: HashMap - all key-value pairs from this HashMap are added to hashMap1

overwriteExisting: Boolean - (Optional, default: false) if true, keys from hashMap1 that also exist in hashMap2 are overwritten. When set to true, merging is faster

Return Value:

Nothing

Examples

Example 1:

_hashMap merge _otherHashMap;

Example 2:

private _hashmap1 = ["cow", "cat", "chicken"] createHashMapFromArray [100, 200, 200]; private _hashmap2 = ["cow", "cat", "chicken", "camel"] createHashMapFromArray [150, 300, 400, 800]; _hashmap1 merge _hashmap2; // _hashmap is [["cow",100],["cat",200],["chicken",200],["camel",800]]

Example 3:

private _hashmap1 = ["cow", "cat", "chicken"] createHashMapFromArray [100, 200, 200]; private _hashmap2 = ["cow", "cat", "chicken", "camel"] createHashMapFromArray [150, 300, 400, 800]; _hashmap1 merge [_hashmap2, true]; // _hashmap is [["cow",150],["cat",300],["chicken",400],["camel",800]]

Example 4:

private _hashmap1 = ["cow", "cat", "chicken"] createHashMapFromArray [100, 200, 200]; private _hashmap2 = ["cow", "cat", "chicken", "camel"] createHashMapFromArray [150, 300, 400, 800]; _hashmap1 merge [_hashmap2, false]; // _hashmap is [["cow",100],["cat",200],["chicken",200],["camel",800]] as Syntax 1
