io.neow3j.devpack.StringLiteralHelper

public class StringLiteralHelper
extends java.lang.Object

Method Detail

addressToScriptHash

public static byte[] addressToScriptHash(java.lang.String address)

Converts the given Neo address to the corresponding script hash as a little-endian byte array.

This method can only be applied to constant string literals.

Example: addressToScriptHash("AFsCjUGzicZmXQtWpwVt6hNeJTBwSipJMS") generates 0102030405060708090a0b0c0d0e0faabbccddee

Parameters:

address - The address to convert to script hash.

Returns:

the script hash.

hexToBytes

public static byte[] hexToBytes(java.lang.String hex)

Converts the given hex string to a byte array.

This method can only be applied to constant string literals.

Example: hexToBytes("0102030405060708090a0b0c0d0e0faabbccddee") generates the corresponding byte array.

Parameters:

hex - The hex string to convert to bytes.

Returns:

the byte array.

stringToInt

public static int stringToInt(java.lang.String text)

Converts the given number string to an integer.

This method can only be applied to constant string literals.

Example: stringToInt("10000") generates the int with the value 10000.

Parameters:

text - The string representation of the integer.

Returns:

the integer.
