public class IP6AddressTextField
extends PatternField

A specialized text field component for IPv6 address input. This class extends the functionality of a PatternField and ensures proper formatting and validation of 8-block hexadecimal IPv6 addresses (e.g., "2001:0db8:85a3:0000:0000:8a2e:0370:7334"). The component enforces a specific pattern and provides auto-padding capabilities for input values to maintain compatibility with the standard 8-block representation of IPv6 addresses.

Constructor Details

IP6AddressTextField

public IP6AddressTextField()

Constructs an instance of IP6AddressTextField, a customized text input component designed specifically for entering and validating IPv6 addresses in the standard 8-block hexadecimal format. This default constructor initializes the text field with a fixed width of 39 characters and uses a pre-configured CustomStringBlockFormatter to enforce the required format. The minimum width of the component is set to "22em" to ensure adequate space for displaying the entire address, maintaining consistency with the 8-block representation.

Method Details

getEmptyValue

public String getEmptyValue()

Specified by:

getEmptyValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<com.vaadin.flow.component.textfield.TextField,String>,String>

Overrides:

getEmptyValue in class com.vaadin.flow.component.textfield.TextField

isInvalid

public boolean isInvalid()

getAddress

public static Inet6Address getAddress(String a)

Retrieves an Inet6Address object for the specified IPv6 address string.

Parameters:

a - the IPv6 address represented as a String. It should follow the standard 8-block hexadecimal format. If the input is null or invalid, the method will return null.

Returns:

an Inet6Address instance corresponding to the specified IPv6 address, or null if the address could not be resolved or an error occurs.

getAddress

public static String getAddress(Inet6Address a)

Retrieves the formatted IPv6 address as a string. If the provided address is null, it returns an empty string.

Parameters:

a - the Inet6Address to be formatted; can be null.

Returns:

the padded and formatted string representation of the IPv6 address, or an empty string if the input is null.
