Types

type Array

type Array struct {
	// contains filtered or unexported fields
}

Array is a golang array with rich features. It contains a concurrent-safe/unsafe switch, which should be set when its initialization and cannot be changed then.

func New

func New(safe ...bool) *Array

New creates and returns an empty array. The parameter `safe` is used to specify whether using array in concurrent-safety, which is false in default.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
)

func main() {
	// A normal array.
	a := garray.New()

	// Adding items.
	for i := 0; i < 10; i++ {
		a.Append(i)
	}

	// Print the array length.
	fmt.Println(a.Len())

	// Print the array items.
	fmt.Println(a.Slice())

	// Retrieve item by index.
	fmt.Println(a.Get(6))

	// Check item existence.
	fmt.Println(a.Contains(6))
	fmt.Println(a.Contains(100))

	// Insert item before specified index.
	a.InsertAfter(9, 11)
	// Insert item after specified index.
	a.InsertBefore(10, 10)

	fmt.Println(a.Slice())

	// Modify item by index.
	a.Set(0, 100)
	fmt.Println(a.Slice())

	fmt.Println(a.At(0))

	// Search item and return its index.
	fmt.Println(a.Search(5))

	// Remove item by index.
	a.Remove(0)
	fmt.Println(a.Slice())

	// Empty the array, removes all items of it.
	fmt.Println(a.Slice())
	a.Clear()
	fmt.Println(a.Slice())

}
Output:

10
[0 1 2 3 4 5 6 7 8 9]
6 true
true
false
[0 1 2 3 4 5 6 7 8 9 10 11]
[100 1 2 3 4 5 6 7 8 9 10 11]
100

If offset is non-negative, the sequence will start at that offset in the array. If offset is negative, the sequence will start that far from the end of the array.

If length is given and is positive, then the sequence will have up to that many elements in it. If the array is shorter than the length, then only the available array elements will be present.

If length is given and is positive, then the sequence will have up to that many elements in it. If the array is shorter than the length, then only the available array elements will be present. If length is given and is negative then the sequence will stop that many elements from the end of the array. If it is omitted, then the sequence will have everything from offset up until the end of the array.

func main() {
	s := garray.NewStrArrayFrom(g.SliceStr{"a", "b", "c"})
	fmt.Println(s.String())

}
Output:

["a","b","c"]

func (*StrArray) SubSlice

func (a *StrArray) SubSlice(offset int, length ...int) []string

SubSlice returns a slice of elements from the array as specified by the `offset` and `size` parameters. If in concurrent safe usage, it returns a copy of the slice; else a pointer.

If offset is non-negative, the sequence will start at that offset in the array. If offset is negative, the sequence will start that far from the end of the array.

If length is given and is positive, then the sequence will have up to that many elements in it. If the array is shorter than the length, then only the available array elements will be present. If length is given and is negative then the sequence will stop that many elements from the end of the array. If it is omitted, then the sequence will have everything from offset up until the end of the array.

Any possibility crossing the left border of array, it will fail.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/frame/g"
)

func main() {
	s := garray.NewStrArray()
	s.SetArray(g.SliceStr{"a", "b", "c", "d", "e", "f", "g", "h"})
	r := s.SubSlice(3, 4)
	fmt.Println(r)

}
Output:

[d e f g]

func (*StrArray) Sum

func (a *StrArray) Sum() (sum int)

Sum returns the sum of values in an array.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/frame/g"
)

func main() {
	s := garray.NewStrArray()
	s.SetArray(g.SliceStr{"3", "5", "10"})
	a := s.Sum()
	fmt.Println(a)

}
Output:

18

func (*StrArray) Unique

func (a *StrArray) Unique() *StrArray

Unique uniques the array, clear repeated items. Example: [1,1,2,3,2] -> [1,2,3]

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/frame/g"
)

func main() {
	s := garray.NewStrArray()
	s.SetArray(g.SliceStr{"a", "b", "c", "c", "c", "d", "d"})
	fmt.Println(s.Unique())

}
Output:

["a","b","c","d"]

func (*StrArray) UnmarshalJSON

func (a *StrArray) UnmarshalJSON(b []byte) error

UnmarshalJSON implements the interface UnmarshalJSON for json.Unmarshal.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/internal/json"
)

func main() {
	b := []byte(`{"Id":1,"Name":"john","Lessons":["Math","English","Sport"]}`)
	type Student struct {
		Id      int
		Name    string
		Lessons *garray.StrArray
	}
	s := Student{}
	json.Unmarshal(b, &s)
	fmt.Println(s)

}
Output:

{1 john ["Math","English","Sport"]}

func (*StrArray) UnmarshalValue

func (a *StrArray) UnmarshalValue(value interface{}) error

UnmarshalValue is an interface implement which sets any type of value for array.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/util/gconv"
)

func main() {
	type Student struct {
		Name    string
		Lessons *garray.StrArray
	}
	var s *Student
	gconv.Struct(g.Map{
		"name":    "john",
		"lessons": []byte(`["Math","English","Sport"]`),
	}, &s)
	fmt.Println(s)

	var s1 *Student
	gconv.Struct(g.Map{
		"name":    "john",
		"lessons": g.SliceStr{"Math", "English", "Sport"},
	}, &s1)
	fmt.Println(s1)

}
Output:

&{john ["Math","English","Sport"]}
&{john ["Math","English","Sport"]}

func (*StrArray) Walk

func (a *StrArray) Walk(f func(value string) string) *StrArray

Walk applies a user supplied function `f` to every item of array.

Example
package main

import (
	"fmt"

	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/frame/g"
)

func main() {
	var array garray.StrArray
	tables := g.SliceStr{"user", "user_detail"}
	prefix := "gf_"
	array.Append(tables...)
	// Add prefix for given table names.
	array.Walk(func(value string) string {
		return prefix + value
	})
	fmt.Println(array.Slice())

}
Output:

[gf_user gf_user_detail]
