IntegerConverter

Description

The IntegerConverter class allows you to convert arbitrary values into integers using the following extended conversion rules:

• Strings are converted to floats, then to integers
• DateTime: total number of milliseconds since unix epoch
• Boolean: 1 for True and 0 for False

Static methods

toInteger

Converts a value into an integer or returns 0 when the conversion is not possible.
See LongConverter.toLong,
LongConverter.toLongWithDefault

public static toInteger(value: any): number

• value: any - value to convert.
• returns: number - integer value or 0 when the conversion is not supported.

toIntegerWithDefault

Converts a value into an integer or returns a given default value when the conversion is not possible. See LongConverter.toLongWithDefault,
LongConverter.toNullableLong

public static toIntegerWithDefault(value: any, defaultValue: number): number

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

toNullableInteger

Converts a value into an integer or returns null when the conversion is not possible. See LongConverter.toNullableLong

public static toNullableInteger(value: any): number

• value: any - value to convert.
• returns: number - integer value or null when the conversion is not supported.

Examples

let value1 = IntegerConverter.toNullableInteger("ABC"); // Result: null
let value2 = IntegerConverter.toNullableInteger("123.456"); // Result: 123
let value3 = IntegerConverter.toNullableInteger(true); // Result: 1
let value4 = IntegerConverter.toNullableInteger(new Date()); // Result: current milliseconds (E.g. 1619869474907)
