BooleanConverter

Description

The BooleanConverter class allows you to convert different values into boolean values using the following rules:

• Numbers: <>0 are true, =0 are false

• Strings: “true”, “yes”, “T”, “Y”, “1” are true; “false”, “no”, “F”, “N” are false

• DateTime: <>0 total milliseconds are true, =0 are false

Static methods

toBoolean

Converts a value into a boolean or returns false when conversion is not possible.

public static toBoolean(value: any): boolean

• value: any - value to convert.
• returns: boolean - boolean value or false when the conversion is not supported.

toBooleanWithDefault

Converts a value into a boolean or returns a given default value when the conversion is not possible

public static toBooleanWithDefault(value: any, defaultValue: boolean = false): boolean

• value: any - value to convert.
• defaultValue: boolean - default value
• returns: boolean - boolean value or given default when the conversion is not supported.

toNullableBoolean

Converts a value into boolean or returns null when the conversion is not possible.

public static toNullableBoolean(value: any): boolean

• value: any - value to convert.
• returns: boolean - boolean value or null when the convertion is not supported.

Examples

let value1 = BooleanConverter.toNullableBoolean(True)     // Returns True
let value2 = BooleanConverter.toNullableBoolean("yes")    // Returns True
let value3 = BooleanConverter.toNullableBoolean(123)      // Returns null
let value4 = BooleanConverter.toNullableBoolean({})       // Returns null

let value5 = BooleanConverter.toBooleanWithDefault(True,"verdadero")     // Returns True
let value6 = BooleanConverter.toBooleanWithDefault(123,"verdadero")      // Returns verdadero

let value7 = BooleanConverter.toBoolean("yes")     // Returns True
